In this paper we apply social epistemology to mathematical proofs and their role in mathematical knowledge. The most famous modern collaborative mathematical proof effort is the Classification of Finite Simple Groups. The history and sociology of this proof have been well-documented by Alma Steingart (2012), who highlights a number of surprising and unusual features of this collaborative endeavour that set it apart from smaller-scale pieces of mathematics. These features raise a number of interesting philosophical issues, but have received (...) very little attention. In this paper, we will consider the philosophical tensions that Steingart uncovers, and use them to argue that the best account of the epistemic status of the Classification Theorem will be essentially and ineliminably social. This forms part of the broader argument that in order to understand mathematical proofs, we must appreciate their social aspects. (shrink)

It is a piece of philosophical common sense that belief and knowledge are states. Some epistemologists reject this claim in hope of answering certain difficult questions about the normative evaluation of belief. I shall argue, however, that this move offends not only against philosophical commonsense but also against ordinary common sense, at least as far as this is manifested in the semantic content of the words we use to talk about belief and knowledge. I think it is relatively (...) easily to show with some linguistic tests that ordinary belief and knowledge attributions should be classified aspectually as state descriptions. Hence, the move some epistemologists to deny that belief and knowledge are states threatens to simply change the topic rather than open up answers to difficult questions in epistemology. I do not know fully how to answer the relevant questions about the normative evaluation of belief, but I pursue this critical point here in service of a positive proposal about the general framework in which they should be answered. In brief, the general framework is one which recognizes an important place for what I call state-norms, beside the action-norms which are more familiar from normative theory. And it locates the epistemic norms that apply to beliefs and are relevant for knowledge on the state-norm side of this divide. This turns out to be not only consistent with but indeed to underwrites the philosophical and ordinary common sense that belief and knowledge are states. (shrink)

Many years ago Wilamowitz desiderated a systematic collection of the texts which relate to the different types of poetry composed by the great lyric poets of Greece. He hoped that if we could only crystallize our admittedly scanty information about the characteristics of, say, the Paean or the Dirge, we might be able to reach a slightly better understanding than we have now of the formal structure and artistic design of the poems and fragments which have come down to us (...) under these titles. Indeed, this kind of knowledge is very important. (shrink)

The classification of unvoiced stops in consonant–vowel syllables, segmented from continuous speech, is investigated by features related to speech production. As burst and vocalic transitions contribute to identification of stops in the CV context, features are computed from both regions. Although formants are the truly discriminating articulatory features, their estimation from the speech signal is a challenge especially in unvoiced regions like the release burst of stops. This may be compensated partially by sub-band energy-based features. In this work, formant (...) features from the vocalic region are combined with features from the burst region comprising sub-band energies, as well as features from a formant tracking method developed for unvoiced regions. The overall combination of features at the classifier level obtains an accuracy of 84.4%, which is significantly better than that obtained with solely sub-band features on unvoiced stops in CV syllables of TIMIT.

What Russell regarded to be the ‘chief outcome’ of his 1914 Lowell Lectures at Harvard can only be fully appreciated, I argue, if one embeds the outcome back into the ‘classificatory problem’ that many at the time were heavily engaged in. The problem focused on the place and relationships between the newly formed or recently professionalized disciplines such as psychology, Erkenntnistheorie, physics, logic and philosophy. The prime metaphor used in discussions about the classificatory problem by British philosophers was a spatial (...) one, with such motifs as ‘standpoints’, ‘place’ and ‘perspectives’ in the space of knowledge. In fact, Russell’s construction of a perspectival space of six-dimensions was meant precisely to be a timely solution to the widely discussed classificatory problem. (shrink)

In this study, the classification of Zaydī fuqahā’ that emerged in the mutaaḫḫirūn period of Zaydī fiqh and related terms are examined. The book named Bulūgh al-arab wa-kunūz al-dhahab fī-maʿrifat al-madhhab, which has great importance among the studies aiming to present the Zaydī fiqh accumulation as a uniform doctrinal structure was taken as a basis in the processing of the subject. After an introduction in which Zaydī fiqh studies are evaluated in their relationship with the subject, the issue is (...) handled under three main headings. In the first title, the author and his work are introduced, and in the second and third titles, the methods and terms used in the classification of the Zaydī fukahâ are examined. The author of the work is ʿAlī b. ʿAbd Allāh al-Shaharī (d. 1190/1776) who lived during the period of the Qāsimī dynasty (al-dawla al-Qāsimiyya) in Yemen. The most important feature of the work, which was prepared using many sources that were attributed importance among the Zaydī literature, is that it was the most comprehensive of all that had written on madhhab doctrine until then. The first part of the work explains that the right madhhab to be followed is Zaydiyya. In the second part, the classes of the Zaydī fuqahā’, which is the subject of our study, are explained. The fuqahā’ classes are primarily divided into two parts: al-salaf al-ṣāliḥīn and al-ḫalaf al-ṣāliḥīn. The first dates back to the beginning of the 3rd/10th century. This class is divided into two parts, as al-sābiqūn and al-mutaaḫḫirūn. The sābiqūn starts with ʿAlī b. Abī Ṭālib, his two sons al-Ḥasan and Ḥusayn and ends with the sons of twelve imams who are their descendants. Zayd b. ʿAlī (d. 122/740) is one of the twelve imams. The most important of the faqīhs in the part of mutaaḫḫirūn, which started with al-Qāsim b. Ibrāhīm al-Rassī (d. 246/860), are the six imams called ahl-al-nuṣūṣ or aʾimma al-nuṣūṣ. The reason why they are named as such is that their words were taken as a basis in determining the views of the sect on the field of uṣūl and furūʿ l-fiqh. al-Qāsim al-Rassī is at a point where all the knowledge of the Prophet's family and the principles agreed upon by sābiqūn, reach him through many channels. al-Hādī Yaḥyā b. al-Ḥusayn (d. 298/911), grandson of al-Qāsim, is the most important imam in terms of his position in the madhhab. The ḫalaf al-ṣāliḥīn is also divided into two parts as ahl l-taḥṣīl and ahl l-naẓar. The first part also referred to as muḥaṣṣilūn or aʾimma al-taḥṣīl, has no subcategories. The second part is divided into two sub-sections as ahl l-taqrīr and mudhākirūn. The muḥaṣṣilūn class starts with those who catch up with the last class of ahl al-nuṣūṣ and ends with ʿAbd Allāh b. Ḥamza (d. 614/1217), one of the three important imams. Two other important imams of muḥaṣṣilūn are Aḥmad b. al-Huṣayn (d. 411/1020) and his brother Yahyā b. al-Husayn (d. 424/1032). It is the fiqh activity of the jurists of this class, called taḥṣīl l-madhhab, that brought Zaydī fiqh, which was fiqh of imams (madhāhib l-aʾimma) in its first period, into a single madhhab and to its classical form in the last period. Mudhākirūn jurists lived at the same time as the ahl-t-taqrīr. This period is about 700 years from the beginning of the 6th/12th century, which is the last century of the muḥaṣṣilūn class, to the end of the 12th/18th century, when Shaharī lived. The roles of the ahl al-taqrīr in the madhhab mostly consist of reviewing the works of the ahl-l tahṣīl, approving the correct ones, and correcting the wrong ones. That's why they are so named. The author of Kitāb l-Azhār, Aḥmad b. Yaḥyā l-Murtaḍā (d. 840/1437), is one of the prominent jurists among the ahl l-taqrīr. The majority of Zaydi fuqahā’ belong to the muẕākirūn class. These are the lowest class of the ahl-al-naẓar. As an important result reached in the study, it is possible to express the following: There is a difference between some of the knowledge and opinions in modern Zaydī studies, which include the same subject as Shaharī's work, in terms of the classification of Zaydī fuqahā’ and the terms used. Therefore, the findings and conclusions based on this work should be confirmed by new studies on other Zaydī classics, and existing opinions on Zaydī jurisprudence should be reviewed. (shrink)

„Errors are the greatest obstacles to the progress of science; to correct such errors is of more practical value than to achieve new knowledge,“ asserted Eugen Bleuler. Basic error of several prevailing classification schemes of pathological conditions, as for example ICD-10, lies in confusing and mixing symptoms with diseases, what makes them unscientific. Considering the need to bring order into the chaos and light into terminological obscureness, I introduce the Causal classification of diseases originating from the notion (...) of bodily wholeness and causality of its loss.

The morality of tendering practices is an issue of economic and social significance, especially when large government contracts are involved. Criticisms are mostly concentrated around collusive tendering: illegal agreements between tenderers that result in seemingly competitive bids, price fixing or market distribution schemes that circumvent the spirit of free competition and defraud clients. Although collusion has been identified as an endemic malaise of tendering, its behavioural and moral dimensions have not been systematically studied before. The paper addresses this knowledge (...) gap and describes part of an exploratory empirical investigation of the decision-making patterns utilised by estimators in Australia'slargest construction organisations.

Failings of a categorical systemFor decades, standardized classification systems have attempted to define psychiatric disorders in our mental health care system, with the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association (APA), 2013) and International Statistical Classification of Diseases and Related Health Problems 10th revision (ICD-10; World Health Organization, 2010) being internationally best-known. One of the major advantages of the DSM must be that it has seriously diminished the international linguistic confusion regarding psychiatric (...) disorders. Since its introduction, it contributed extensively towards one common international language for defining and conceptualizing psychiatric disorders. Strikingly, within the field of psychological testing a similar step forward seems to have not yet been taken. At present, there exists no international standard for the use of psychological tests that takes the definition of a specific symptom as listed in DSM-5 as its starting point, and reliably and validly measures this symptom. Rather, the majority of tests are measuring constructs consisting of a multitude of symptoms. For example, the Beck’s Depression Inventory (Beck et al., 1996) measures core symptoms of depression summing up to a depression score. Accordingly, we believe it is time for a change. The diagnostics of psychiatric disorders, where disorders are defined as nosological units with a single cause, a single organic substrate, and a single time course, has been problematic for centuries. The field of psychiatry has always been ambivalent about its desire to follow a medical model (Blaney, 2015), but afflicted due to its definitions of pathology. The definition of a psychiatric disorder in DSM-5 offers little room for a clear cut pathogenesis and harsh demarcation of syndromes. This is reflected in the DSM-5, where it states: “A mental disorder is a syndrome characterized by clinically significant disturbance in an individual’s cognition, emotion regulation, or behavior that reflects a dysfunction in the psychological, biological, or developmental processes underlying mental functioning” (APA, 2013, p.20). An unfortunate and recognized consequence of this definition within the current system is that many symptoms overlap within categories of psychiatric disorders and patients end up diagnosed with many co-morbid disorders.Two fundamental problemsRegardless of new attempts to improve the diagnostics of psychiatric disorders, the DSM-5 represents the status quo. Consequently, the distinction between diagnosis and classification remains substantial and more than a discussion on semantics. We identify two fundamental problems within the current framework. Generally, a psychiatric diagnosis is considered to be descriptive (Hengeveld and Schudel, 2003). The clinician will describe a syndrome (its nature, timespan, and severity) within the framework of a disorder, and often include a differential diagnosis, predisposing protective or vulnerability factors, and provoking or maintaining factors. Within the DSM-5 framework, a similar ‘approach to clinical case formulation’ is taken (APA, 2013, p. 19). Evidently, a descriptive diagnosis has a hypothetical character. It consists of the clinician’s hypothesis and is based on his or hers professional considerations according to the abovementioned factors. Once the clinician has formulated a descriptive diagnosis, it is then complementary ‘translated’ into a DSM-5 classification. Herein lies the problem. For the layman, the existence of this distinction between diagnosis and classification is usually unknown. Preceding treatment, the clinician will give the client a classification of the existing psychiatric problems and the client may attribute more meaning to it than appropriate, thereby fostering the risk of reification. Second, the DSM-5 is a categorical system. Thus, individual disorders are regarded as discrete units – ‘you either have it, or you don’t’. DSM-5 states about this: “(…) scientific evidence places many, if not most, disorders on a spectrum with closely related disorders that have shared symptoms, shared genetic and environmental risk factors (…)”. And “(…) we have come to recognize that the boundaries between disorders are more porous than originally perceived.” (APA, 2013, p. 6). This leads to a fundamental problem. Because the overwhelming majority of psychiatric disorders examined thus far using taxometric methods appear to be dimensional in nature (Haslam, 2003; Widiger and Samuel, 2005), consequently all of their categorizations become artificial and debatable. Even though DSM-5 took a modest step towards a more dimensional approach, its core remains categorical. To illustrate, consider the Borderline Personality Disorder (BPD). This classification consists of nine diagnostic criteria of which a minimum of five need to be present for the diagnosis of BPD. A simple numerical combination algorithm leads to a staggering number of 256 distinct presentations of BPD (Albion et al., 2013). Due to this chameleon-like nature, the disorder’s diagnostic validity becomes questionable. Strikingly, this number is relatively small when compared to other conditions, e.g., there are 636,120 ways to have posttraumatic stress disorder (Galatzer-Levy and Bryant, 2013).DSM-5 does propose an alternative model for personality disorders based on personality functioning and traits (APA, 2013, p. 761), as a possible answer to the problem that most patients fit with multiple co-morbid personality disorders or to the category of personality disorder not otherwise specified. In November 2012, the chair committee of APA decided to move this alternative model to section III of DSM-5 and to sustain the categorical system in section II. A potential solutionDSM-5 and its predecessors have brought about an invaluable improvement regarding the formulation of a common international language for psychiatric disorders. However, the individual disorders fit poorly with its starting point of discrete units and strict boundaries. Van Os (2014) has argued for a better balance between the categorical and personalized aspects of psychiatric disorders. We argue for a two-step approach.Particularly due to the ‘weak boundaries’ between disorders, it might be beneficial to limit ourselves by merely categorizing clients into the main categories of the DSM-5 according to their most prominent symptoms (Van Os, 2014), i.e. their main complaint. In other words, clinicians could first ask themselves whether the symptomatology is concerning a neurodevelopmental disorder, or a bipolar and related disorder, or a depressive disorder, and so on. It will drastically reduce the over 400 classifications in DSM-5 down to 20 categories. Van Os (2014) even argues to combine some of the main categories, reducing this number even further to 15 categories. The advantages of reducing the over 400 classifications are fivefold: 1) a syndrome, being an aggregation of symptoms, creates a false relation between symptoms that are that are already heterogeneous themselves; 2) 15 broad categories are functional: it results into a very heterogeneous group of clients within a category and thus prevents stereotypes and invites further personalizing of complaints; and 3) a dimensional measure of a symptom rather than a syndrome will correspond better with the client regardless of it not providing the complete picture. Focusing on the main complaint will indicate where there is an immediate need for care (Van Os, 2014); 4) it will allow clinicians to recognise subthreshold conditions more easily (Magruder and Calderone, 2000); and 5) it might facilitate the development of clear demarcations between normal and abnormal functioning (Kessler, 2002; Widiger and Samuel, 2005). Please, see also Table 1.This also fits well within scientific advances, as thus far strongest evidence has been found for a distinction between internalizing and externalizing disorders, even superseding these 15 main categories (DSM-5; APA, 2013, p.13, but see Weiss et al., 1998). The second step would concern the personalized aspect, which we argue to define on a level of core symptoms of the specific main category, to be agreed upon later. To assess these core symptoms, the field of psychological testing could develop an internationally applicable instrument to reliably and validly measure each (core) symptom on a dimensional scale. Many of these instruments are readily available and have proven its psychometric properties within scientific research. Elements from these instruments could be easily transformed to work within the new system. Within the field of psychology, this approach could aid development of a common international language to define symptoms, analogous to the field of psychiatry. Importantly, current psychological testing mainly implies the use of self-report measures. This leads to an abundance of auto-amnestic information. To increase the reliability and validity of psychological tests to assess DSM-5 symptoms, it may be important to add two additional information resources. This would entail psychological tests where a next of kin answers questions about the symptom of the client, and psychological tests that include the clinicians’ judgment, such as structured clinician-based interviews. Conversely, we also need to acknowledge the well-known limitations of clinical judgment (e.g., Faust, 1986; Garb, 1998). Advantages of a new frameworkThe changes we suggest have big implications and are not easily implemented in the current framework. Clients may prefer the comfort of a single clear label, similar to what they are used to in other areas of medicine. Health insurance providers and policy makers may argue for single labels as well. Therefore, it would require a lot of explanation from our clinicians to promote a change. Our suggestions for broader categories may not disambiguate the current situation better than the existing approach, but it will promote personalisation of health care. Difficulties in diagnostic reliability will remain in disorders that fall on the boundaries of the taxons, e.g., schizoaffective disorder versus bipolar disorder with psychotic characteristics, which may benefit from further study. There are also some politically tinged questions to keep in mind: How will we finance our health care, and how will we ensure a gradual transition from the current financing system, including clients who already have their labels? What about visitations from insurers and health inspection? How can they control for a good standard of quality in health care when considering the increasing heterogeneity? Nevertheless, we argue that the benefits outweigh the disadvantages. We will see a shift from a categorical to a personalized approach, which will lead to less (self) stigmatizing, less estrangement, and it will challenge reification thinking. DSM-V states that “a reformulation of research goals should also keep DSM-5 central to the development of dimensional approaches to diagnosis that will likely supplement or supersede current categorical approaches to diagnosis in coming years” (APA, 2013, p. 13). Our proposition for psychological testing on symptom level could contribute to this development. Furthermore, this new approach will do more justice to the heterogeneity of symptoms within and outside of classification categories, see also Table 1. Moreover, in this new approach we join forces of expert knowledge from the fields of psychiatry and psychological science. Finally, it offers new and potentially better opportunities to map health care needs. This in turn will lead to a better interface for allocation of appropriate treatment. It will present a clearer picture of when preventative care is preferred over treatment and vice versa. Importantly, health care needs will be more closely attuned to the ‘own story’ of the client.We argue for the national and international psychological associations in Europe and the United States of America to support the idea of a collective approach to develop an internationally standardized psychological testing battery to reliably assess all the core symptoms of the main categories in DSM-5.

Preoperative diagnosis of gastric cancer and primary gastric lymphoma is challenging and has important clinical significance. Inspired by the inductive reasoning learning of the human brain, transfer learning can improve diagnosis performance of target task by utilizing the knowledge learned from the other domains (source domain). However, most studies focus on single-source transfer learning and may lead to model performance degradation when a large domain shift exists between the single-source domain and target domain. By simulating the multi-modal information learning (...) and transfer mechanism of human brain, this study designed a multisource transfer learning feature extraction and classification framework, which can enhance the prediction performance of the target model by using multisource medical data (domain). First, this manuscript designs a feature extraction network that takes the maximum mean difference based on the Wasserstein distance as an adaptive measure of probability distribution and extracts the domain-specific invariant representations between source and target domain data. Then, aiming at the random generation of parameters bringing uncertainties to prediction accuracy and generalization ability of extreme learning machine network, the 1-norm regularization is used to implement sparse constraints of the output weight matrix and improve the robustness of the model. Finally, some experiments are carried out on the data of two medical centers. The experimental results show that the area under curves (AUCs) of the method are 0.958 and 0.929 in the two validation cohorts, respectively. The method in this manuscript can provide doctors with a better diagnostic reference, which has certain practical significance. (shrink)

Community technology design has been deeply affected by paradigm shifts and dominant discourses of its seminal disciplines, such as Human Computer Interaction, Cultural and Design theories, and Community Development as reflected in Community Narratives. A particular distinction of community technology design endeavours has been their cultural stance, which directs the agendas, interactions, and outcomes of the collaboration. Applying different cultural lenses to community technology design, shifts not only practices but also directs the levels of awareness, thereby unfolding fundamentally distinct cultural (...) engagement approaches. Previous community technology design research indulged in cross-, inter-, and multicultural approaches to community engagement; it was occupied with meticulously deconstructing and reconstructing perspectives, interactions, roles, and agendas. We argue that when deeply immersed in joint design activities in long-term collaborations, we look beyond individual cultures and enter a transcultural mode of engagement. A transcultural community technology design endeavour supports a continuous creation and re-creation of new meanings, originating from individual entities yet being diffused and continuously reflected within the existing design space. We suggest that within community technology design, a context with abundant cultural diversity, a heightened awareness becomes a necessity. We exemplify different instantiations of the cultural engagement approaches within our long-term collaborations and technology design projects with indigenous communities in Malaysian Borneo and Namibia. A transcultural approach to indigenous knowledge preservation and digitisation efforts with indigenous communities opens up a controversial debate about protecting versus integrating local epistemologies.

During the twentieth century, bibliographic classification theory underwent a structural revolution. The first modern bibliographic classifications were top-down systems that started at the universe of knowledge and subdivided that universe downward to minute subclasses. After the invention of faceted classification by S.R. Ranganathan, the ideal was to build bottom-up classifications that started with the universe of concepts and built upward to larger and larger faceted classes. This ideal has not been achieved, and the two kinds of (...) class='Hi'>classification systems are not mutually exclusive. This paper examines the process by which this structural revolution was accomplished by looking at the spread of facet theory after 1924 when Ranganathan attended the School of Librarianship, London, through selected classification textbooks that were published after that date. To this end, the paper examines the role of W.C.B. Sayers as a teacher and author of three editions of The Manual of Classification for Librarians and Bibliographers. Sayers influenced both Ranganathan and the various members of the Classification Research Group (CRG) who were his students. Further, the paper contrasts the methods of evaluating classification systems that arose between Sayers’s Canons of Classification in 1915–1916 and J. Mills’s A Modern Outline of Library Classification in 1960 in order to demonstrate the speed with which one kind of classificatory structure was overtaken by another. (shrink)

This paper examines the predominant systems used for the classification of print-based cartographic materials (primarily atlases and sheet maps). We present the results of a brief, widely distributed survey on the topic, followed by discussions of the distinctive characteristics of the classification systems used by survey respondents.

Technological change is widely studied in economic discourse, dominated by an “industrial perspective” in which scientific and engineering advances are categorized by, and analyzed in the context of, industrial classifications. The present study compares this perspective with the alternative approach of studying the effects of scientific advances onproducts (goods and services) in the context of the functions those products serve. Using a function-based classification scheme, data on the economic effects of scientific advances are developed from articles appearing in business (...) journals. These data present a different picture of evolutionary economic change, which may shed additional light on its causality. (shrink)

The scheme for classifications of concepts is introduced. It has founded on the triplet model of concepts. In this model a concept is depicted by means of three kinds of knowledge: a concept base, a concept representing part and the linkage between them. The idea of triplet classifications of concepts is connected with a usage of various specifications of these knowledge kinds as classification criteria.

A review is undertaken of the contributions of 38 classical authors, from Pythagoras in the 6th century BCE to Isidore in the 6th century CE, to the classification of the sciences. Such classifications include some that are more theoretical in function, some that are more practical.

The use of automation in cars is increasing. In future vehicles, drivers will no longer be in charge of the main driving task and may be allowed to perform a secondary task. However, they might be requested to regain control of the car if a hazardous situation occurs. Performing a secondary task might increase drivers' mental workload and consequently decrease the takeover performance if the workload level exceeds a certain threshold. Knowledge about the driver's mental state might hence be (...) useful for increasing safety in conditionally automated vehicles. Measuring drivers' workload continuously is essential to support the driver and hence limit the number of accidents in takeover situations. This goal can be achieved using machine learning techniques to evaluate and classify the drivers' workload in real-time. To evaluate the usefulness of physiological data as an indicator for workload in conditionally automated driving, three physiological signals from 90 subjects were collected during 25 min of automated driving in a fixed-base simulator. Half of the participants performed a verbal cognitive task to induce mental workload while the other half only had to monitor the environment of the car. Three classifiers, sensor fusion and levels of data segmentation were compared. Results show that the best model was able to successfully classify the condition of the driver with an accuracy of 95%. In some cases, the model benefited from sensors' fusion. Increasing the segmentation level increased the performance of the model for windows smaller than 4 min, but decreased for windows larger than 4 min. In conclusion, the study showed that a high level of drivers' mental workload can be accurately detected while driving in conditional automation based on 4-min recordings of respiration and skin conductance.

This paper presents an in-depth study and analysis of the emotional classification of EEG neurofeedback interactive electronic music compositions using a multi-brain collaborative brain-computer interface (BCI). Based on previous research, this paper explores the design and performance of sound visualization in an interactive format from the perspective of visual performance design and the psychology of participating users with the help of knowledge from various disciplines such as psychology, acoustics, aesthetics, neurophysiology, and computer science. This paper proposes a specific (...) mapping model for the conversion of sound to visual expression based on people’s perception and aesthetics of sound based on the phenomenon of audiovisual association, which provides a theoretical basis for the subsequent research. Based on the mapping transformation pattern between audio and visual, this paper investigates the realization path of interactive sound visualization, the visual expression form and its formal composition, and the aesthetic style, and forms a design expression method for the visualization of interactive sound, to benefit the practice of interactive sound visualization. In response to the problem of neglecting the real-time and dynamic nature of the brain in traditional brain network research, dynamic brain networks proposed for analyzing the EEG signals induced by long-time music appreciation. During prolonged music appreciation, the connectivity of the brain changes continuously. We used mutual information on different frequency bands of EEG signals to construct dynamic brain networks, observe changes in brain networks over time and use them for emotion recognition. We used the brain network for emotion classification and achieved an emotion recognition rate of 67.3% under four classifications, exceeding the highest recognition rate available. (shrink)

The knowledge in the context of COVID-19 pandemic must be viewed from the perspective of its purpose: the intention to limit the effects and spread of SARS-CoV-2, respectively to cancel them. In order to increase the level of knowledge we identify some of the possible classifications, based on them allowing a first outline of uncertainty. The purpose of the analysis is to contribute to the clearest possible identification of the known and the unknown, thus creating a more stable (...) cognitive field for effective public health decisions. Given that measures to combat the COVID-19 pandemic along with its effects is one of humanity's priorities, it is useful to clear up some of the issues that are likely to have improper meanings. The identification of each situation that includes significant doses of unknown and the public recognition of the uncertainty represents the condition for the possibility of robust public policies. Indicating the place that each current aspect occupies in one of the four cognitive quadrants is an important cognitive work. The position we adopt is characteristic for cognitive skepticism, trying to indicate some of the knowledge`s limits of and the risks of pseudo-knowledge. The article is a theoretical approach, based on some epistemological principles of critical thinking, the starting point being the belief that knowing what you do not know is an essential part of the knowledge.

Millikan's account of how we acquire our most basic concepts might be clarified by a better ontological taxonomy, especially one that distinguishes between natural kinds on the one hand and wholes composed of parts on the other. The two have a different causal basis, which is important because once classification goes beyond the stage of naive induction, it becomes fundamentally etiological.

Plurality of beliefs and theories in different knowledge domains calls for modelling multi-viewpoint ontologies and knowledge organization systems. A generic theoretical approach recently proposed for heterogeneity representation in KOS was linking each ontological statement to a specific validity scope to determine a set of conditions under which the statement is valid. However, the practical applicability of this approach has yet to be empirically assessed. In addition, there is still a need to investigate the types of inconsistencies that might (...) arise in multi-viewpoint ontologies as well as their possible causes. This study proposes a new framework for systematic analysis and classification of inconsistencies in multi-viewpoint ontologies. The framework is based on eight generic logical structures of ontological statements. To test the validity of the proposed framework, two ontologies from different knowledge domains were examined. We found that only three of the eight structures led to inconsistencies in both ontologies, while the other two structures were always present in logically consistent statements. The study has practical implications for building diversified and personalized knowledge systems. (shrink)

Dual innovation, which includes exploratory innovation and exploitative innovation, is crucial for firms to obtain a sustainable competitive advantage. The knowledge base of firms greatly influences or even determines the scope, direction, and path of their dual-innovation activities, which drive their innovation process and produce different innovation performances. This study uses data source patents obtained by 285 focal firms in the Chinese new-energy vehicle industry in the period 2015–2020. Five knowledge-base features are selected by analyzing the correlation and (...) multicollinearity, and four different firm clusters are found by using the k-means clustering algorithm. Based on the classification and regression tree algorithm, we mine the potential decision rules governing the dual-innovation performance of firms. The results show that the exploratory innovation performance of firms in different clusters is mainly affected by two different knowledge-base features. Knowledge-base scale is a key factor affecting the exploitative innovation performance of firms.

This collection of essays addresses, in specific historical ways and from particular disciplinary standpoints, the problem of knowledge and what used to be called the classification of the sciences. What is, or what passes for, knowledge? What are its divisions, and how should they be related? Who possesses this knowledge, (...) and to what uses has it been put? How is it transmitted, and how can its history be understood and written? Ranging across the epistemological barrier formed by the revolution of modern science, these contributions inquire into the changing disciplinary patterns of the tumultuous times between the renaissance and the enlightenment, that saw the fragmentation of old ideals and the creation of European modernity. Contributors: Donald R. Kelley, Ann Blair, Paul Nelles, Constance Blackwell, Ulrich Schneider, Martin Mulsow, J.B. Schneewind, Donald Verene, Peter Miller, Ann Moyers, Michael Seidler, Anthony Pagden, Paula Findlen, Anthony Grafton, Heikki Mikkeli, Nicholas Jardine, Londa Schiebinger. (shrink)

Descartes' image of the tree of knowledge from the preface to the French edition of the Principles of Philosophy is usually taken to represent Descartes' break with the past and with the fragmentation of knowledge of the schools. But if Descartes' tree of knowledge is analyzed in its proper context, another interpretation emerges. A series of contrasts with other classifications of knowledge from the seventeenth and eighteenth centuries raises some puzzles: claims of originality and radical break (...) from the past do not seem warranted. Further contrasts with Descartes' unpublished writings and with school doctrines lead to the ironic conclusion that, in the famous passage, Descartes is attempting to appeal to conventional wisdom and trying to avoid sounding novel.

In modern science, classifications occupy a special place. In many areas of knowledge, they are the canonized type of product of scientific activity. That is why all the information obtained by the researchers tends to formulate in the form of those or other classifications of the investigated objects themselves, their separately considered properties, composition, structure, genesis, placement, etc. However, the quality of already built classifications, as a rule, does not suit the specialists. When creating the same new, there are (...) numerous difficulties, which are impossible to overcome, because there are no theoretical and methodological means. The development of these tools is complicated by the lack of clarity of the very concept of classification, the lack of clear notions of classification as a special phenomenon of knowledge. (shrink)

In post-Revolutionary Mexico, the Indian was conceptualized as a problem that needed to be solved. Indians were believed to be weighing down the nation and thought to constitute an obstacle for fulfilling its promised modern future. Thus, the scientific study of indigenous peoples in Mexico became, in the 1930s, a focus of anthropologists, physicians, and other experts, who sought to learn more about indigenous populations in order to solve this "problem." In this paper I explore how this "problem-solving" was practiced, (...) how and why particular groups of people were used as subjects of inquiry and intervention, how they were selected, and how they enabled the production of knowledge deemed useful to...

In this paper, we present a case study of how well subject metadata (comprising headings from an international classification scheme) has been deployed in a national data catalogue, and how often data seekers use subject metadata when searching for data. Through an analysis of user search behaviour as recorded in search logs, we find evidence that users utilise the subject metadata for data discovery. Since approximately half of the records ingested by the catalogue did not include subject metadata at (...) the time of harvest, we experimented with automatic subject classification approaches in order to enrich these records and to provide additional support for user search and data discovery. Our results show that automatic methods work well for well represented categories of subject metadata, and these categories tend to have features that can distinguish themselves from the other categories. Our findings raise implications for data catalogue providers; they should invest more effort to enhance the quality of data records by providing an adequate description of these records for under-represented subject categories.

C.S. Peirce, the American philosopher and a principal figure in the development of the modern study of semiotics, struggled, mostly during his later years, to work out a systematic method for classifying sciences. By doing this, he hoped to define more clearly the various tasks of these sciences by showing how their individual effects are interrelated and how these effects, considered in their interrelations, establish pragmatic meanings for each individual science. Much of his work was centered on the meaning and (...) function of logic in relation to other areas of human knowledge. By rightly defining the work of logic, Peirce argued, the work of the other sciences could be pursued with more rigorous reasoning. Beverley Kent closely examines the published and unpublished writings of Peirce and carefully attends to the chronological development of his systems of classification; she thereby shows for the first time in the scholarly literature how seeming contradictions in Peirce's evolving classification are really part of an increasingly clear position. Logic, Peirce came to understand, is actually dependent on ethics and aesthetics for its principles. Kent shows how Peirce's working out of the classification of logic in relation to other sciences is a clue to the significant differences between his early and late philosophy and, perhaps even more important, to a reading of his more general claims for a philosophy of "pragmaticism." This work will be of interest to readers of Peirce and American philosophy, to historians of logic and semiotics, and to those more generally interested in the history of systems of knowledge-classification.

Despite continued attention, finding adequate criteria for distinguishing “good” from “bad” scholarly journals remains an elusive goal. In this essay, I propose a solution informed by the work of Imre Lakatos and his methodology of scientific research programmes (MSRP). I begin by reviewing several notable attempts at appraising journal quality – focusing primarily on the impact factor and development of journal blacklists and whitelists. In doing so, I note their limitations and link their overarching goals to those found within the (...) philosophy of science. I argue that Lakatos’s MSRP and specifically his classifications of “progressive” and “degenerative” research programmes can be analogized and repurposed for the evaluation of scholarly journals. I argue that this alternative framework resolves some of the limitations discussed above and offers a more considered evaluation of journal quality – one that helps account for the historical evolution of journal-level publication practices and attendant contributions to the growth (or stunting) of scholarly knowledge. By doing so, the seeming problem of journal demarcation is diminished. In the process I utilize two novel tools (the mistake index and scite index) to further illustrate and operationalize aspects of the MSRP. (shrink)

The author defends the anti-representationalist claim that the formation of the proper names (and as a consequence – scientific terms or notions) cannot happen through certain ostensive pointing at some objects given here and now (like in B. Russell’s theory) or through perceptions which are generalized inductively or by means of Kantian apperception or Anschauung. In order to answer the question about the concepts formation we have to take into account the historical and socio-cultural background of the genesis of proper (...) names which form the foundation and boundary of all classifications including the scientific ones. The author claims that there is an important difference between a personal belief or propositional knowledge and some implicit or background knowledge of the language community in its historical development. The first one could be evaluated on its truth / falseness. The second one however – being the foundation for the first one – cannot be evaluated in this manner. It simply is as it is. (shrink)
