In this paper, we explore the effect of musical expertise on whistled word perception by naive listeners. In whistled words of nontonal languages, vowels are transposed to relatively stable pitches, while consonants are translated into pitch movements or interruptions. Previous behavioral studies have demonstrated that naive listeners can categorize isolated consonants, vowels, and words well over chance. Here, we take an interest in the effect of musical experience on words while focusing on specific phonemes within the context of the word. (...) We consider the role of phoneme position and type and compare the way in which these whistled consonants and vowels contribute to word recognition. Musical experience shows a significant and increasing advantage according to the musical level achieved, which, when further specified according to vowels and consonants, shows stronger advantages for vowels over consonants for all participants with musical experience, and advantages for high‐level musicians over nonmusicians for both consonants and vowels. By specifying high‐level musician skill according to one's musical instrument expertise (piano, violin, flute, or singing), and comparing these instrument groups to expert users of whistled speech, we observe instrument‐specific profiles in the answer patterns. The differentiation of such profiles underlines a resounding advantage for expert whistlers, as well as the role of instrument specificity when considering skills transferred from music to speech. These profiles also highlight differences in phoneme correspondence rates due to the context of the word, especially impacting “acute” consonants (/s/ and /t/), and highlighting the robustness of /i/ and /o/.

Religious beliefs are defined as thinking, feeling and behaving in accordance with the beliefs and teachings of a religious system. In other words, religious beliefs are indicative of the role of religion in the individual and social life of people, as well as adherence to values and beliefs in daily life, performing religious practices and rituals and participating in activities of religious organisations. Religious beliefs are a set of dos and don'ts, and values are considered one of the most important (...) psychological supports that can provide meaning in all moments of life and save a person from meaninglessness by providing explanatory support in specific situations. In addition, work conscience is defined as a feeling of inner commitment to comply with agreed-upon requirements for work. In other words, work conscience means heartfelt satisfaction and practical commitment to the tasks that a person is supposed to perform properly, in a way that there will be no negligence in performing the duty even if no supervisor oversees the activity. Given the significant role of nurses in hospitals, especially during the coronavirus disease 2019 (COVID-19) pandemic, the religious beliefs of healthcare employees have become more important. Therefore, the present study aimed to evaluate the effect of religious beliefs on the work conscience of 1800 Muslim nurses in Iraq during the COVID-19 pandemic in 2021. Standard questionnaires were applied to assess the respondents' religious beliefs and work conscience. In addition, data analyses (Cronbach's alpha, Pearson's correlation, etc.) were performed in Statistical Package for the Social Sciences (SPSS). According to the results, religious beliefs have a positive effect on nurses' work conscience (p = 0.822). CONTRIBUTION: The findings of this study showed that the employees of an organisation, especially nurses and healthcare staff, can rely on their religious beliefs and benefit from their advantages in order to strengthen their work conscience during a hard time such as the COVID-19 pandemic.

AimHealthcare workers have directly provided care for COVID-19 patients, and have faced many additional sources leading to poor mental health. The study aimed to investigate the mental health problems and related factors among healthcare staff in Vietnam.MethodsA descriptive cross-sectional mixed methods study, combining quantitative and qualitative research methods, was performed among 400 healthcare workers working at the National Hospital for Tropical Diseases and Ninh Binh General Hospital from the first day of treatment for COVID-19 patients to May 01, 2020.ResultsThe results (...) showed that 8.0% of participants had stress, 17.5% of participants had anxiety, and 14.8% of participants had depression. Approximately 50% of participants reported that they had at least one of these symptoms. The findings illustrated that stress, anxiety, and depression were associated with the position in a hospital, health status during the COVID-19 pandemic, family members/relatives infected with COVID-19, physical and mental support from friends, family, and community, department, years of working, and the average work hours per day of healthcare workers exposed to COVID-19.ConclusionDuring the COVID-19 pandemic, healthcare workers who worked in the hospital providing treatment and care for COVID-19 patients dealt with mental health problems such as stress, anxiety, and depression. It is necessary to promote mental health among healthcare workers, to contribute to the fight against the COVID-19 outbreak in Vietnam. (shrink)

This article contributes to the limited literatures on small- and medium-size enterprises and corporate social responsibility. Using an institutional theoretical framework, we analyzed fieldwork interviews with twenty SMEs and perspectives of 165 SME managers and workers in textiles, garment, and footwear industries, the most important wage-earning sector in Vietnam. Having understood in the context of a developing “market economy with socialist orientation”, we find that socially responsible practices and expectations developed long before the arrival of CSR as a western concept (...) and an MNC agenda. While identifying and contributing ideas concerning forms of “informal” CSR practices—influenced by social and cultural expectations—to the CSR/sme literature, we are conscious of the mixed effects of these practices and the ongoing nuanced negotiations between workers and managers in these SMEs. In our research, we found that it takes both domestic and international stakeholders to improve labor conditions in Vietnam under the banner of CSR. (shrink)

Nowadays, the power systems are getting more and more complicated because of the delays introduced by the communication networks. The existence of the delays usually leads to the degradation and/or instability of power system performance. On account of this point, the traditional load frequency control approach for power system sketches a destabilizing impact and an unacceptable system performance. Therefore, this paper proposes a new LFC based on adaptive integral second-order sliding mode control approach for the large-scale power system with communication (...) delays. First, a new linear matrix inequality is derived to ensure the stability of whole power systems using Lyapunov stability theory. Second, an AISOSMC law is designed to ensure the finite time reachability of the system states. To the best of our knowledge, this is the first time the AISOSMC is designed for LFC of the LSPSwCD. In addition, the report of testing results presents that the suggested LFC based on AISOSMC can not only decrease effectively the frequency variation but also make successfully less in mount of power oscillation/fluctuation in tie-line exchange.

O confucionismo existe, na vida espiritual do povo vietnamita, desde muito tempo. A parte positiva do Confucionismo pode-se dizer que é o fato de ele contribuir para o fortalecimento das relações familiares, entre os parentes, bem como nas relações sociais de um modo geral; outra parte positiva consiste em motivar as pessoas a desenvolverem o gosto pela leitura e aprendizagem. Estima-se que a ética confucionista precisa ser provocada, a fim de contribuir para a construção da sociedade nos dias atuais. Na (...) contramão dessa positividade, pode-se afirmar que o confucionismo, de maneira geral, não valoriza, na medida necessária, o papel das mulheres na sociedade; na realidade, ele as classifica como pessoas insignificantes. É digno de se observar, entretanto, que, no contexto social específico do Vietnã, as mulheres encontram um lugar próprio na sociedade. Nossa pesquisa visa mostrar exatamente essa diferente concepção do papel da mulher na socidade vietnamita. (shrink)

This paper endeavors to understand the research landscape of finance research in Vietnam during the period 2008 to 2020 and predict the key defining future research directions. Using the comprehensive database of Vietnam’s international publications in social sciences and humanities, we extract a dataset of 314 papers on finance topics in Vietnam from 2008 to 2020. Then, we apply a systematic approach to analyze four important themes: Structural issues, Banking system, Firm issues, and Financial psychology and behavior. Overall, there have (...) been three noticeable trends within finance research in Vietnam: (1) assessment of financial policies or financial regulation, (2) deciphering the correlates of firms’ financial performances, and (3) opportunities and challenges in adopting innovations and ideas from foreign financial market systems. Our analysis identifies several fertile areas for future research, including financial market analysis in the post-COVID-19 eras, fintech, and green finance. (shrink)

Despite increasing scholarly interest in tertiary student perceptions of plagiarism, very little is known about those held by postgraduate students, although differences between undergraduate and PG students relate to both their characteristics and the demands of their studies. Furthermore, there is a dearth of research within the context of international education, where managing plagiarism is seen as a major challenge. This paper reports on a recent online survey with 207 Vietnamese and local PG students at a New Zealand university regarding (...) their perceptions of plagiarism. The findings showed significant differences both between and within the two groups. Perception variations arose from a range of influences and prior experiences, not just the culture in which the students were initially educated. Differences related to participants’ age, gender, academic levels, disciplines, and teaching experience. This study’s findings contribute knowledge about under-researched PG students and problematize prevalent stereotypes of international students regarding plagiarism. They generate implications for higher education institutions to accommodate international and domestic PG student needs in ways that respect their diversities in detail as individuals, not as members of a homogeneous group. Further qualitative research to explore PG student perceptions in greater depth is recommended. (shrink)

Objectives: The official implementation of clinical pharmacy in Vietnam has arrived relatively late, resulting in various stressors. This study aims to evaluate job stress level and suggest viable solutions.Methods: A cross-sectional study was conducted on clinical pharmacists in 128 hospitals in Ho Chi Minh City. Job stress questions were derived from the Healthcare Profession Stress Inventory.Results: A total of 197 CPs participated, giving a response rate of 82.4%. Participants were found to have moderate job stress with an overall mean stress (...) score of 1.5 and stress rate of 52.8%. The sample size was statistically adequate and the HPSI was valid and reliable. Patient care responsibility was the main stressor, especially in public hospitals, followed by job conflicts. Lack of experience, low income, and inability to participate in clinical ward rounds caused significant stress to CPs regarding job recognition and job uncertainty. More practice-oriented training programs in bachelor curricula and clinical practice should be applied to help CPs gain more experience, self-confidence, and diminish job stress.Conclusion: CPs in HCMC have moderate stress. More practice-oriented training programs should be prioritized to lessen stress for CPs. (shrink)

This paper applies a proposed modified stochastic fractal search algorithm (MSFS) for dealing with all constraints of optimal reactive power dispatch (ORPD) and finding optimal solutions for three different cases including power loss optimization, voltage deviation optimization, and L-index optimization. The proposed MSFS method is newly constructed in the paper by modifying three new solution update mechanisms on standard stochastic fractal search algorithm (SSFS). The first modification is to keep only one formula and abandon one formula in the diffusion process (...) while the second modification and the third modification are used in the first update and the second update. In two updates of SSFS, solutions with low quality are updated with high probability while other solutions with high quality do not get chances to be updated. This manner results in the fact that some promising solutions around the high quality solutions can be missed. In order to tackle this restriction, the second modification of MSFS is to newly update the worst solutions in the first update and the best solutions in the second update. In the third modification, all existing formulas of SSFS in the two updates are abandoned and the same new proposed technique is used for updating such solutions in two updates. Compared to SSFS, the three modifications can bring advantages to MSFS such as using smaller number of produced solutions per iteration, spending shorter execution time, finding better optimal solutions, and owning more stable search ability. Furthermore, the proposed method also sees its effectiveness and robustness over SSFS by testing on IEEE 30-bus system and IEEE 118-bus system with three different single objectives for each system. The proposed method can find less minimum, average, and maximum for all the cases in addition to faster search speed. Besides, the proposed method is also compared to other methods such as PSO-based method group, GA-based method group, DE-based method group, and other recent methods. Result comparisons also indicate that the proposed method can be more efficient than almost all these methods with respect to less minimum and smaller values of control parameters. As a result, evaluation of the performance of the proposed method is that it should be used for seeking solutions of ORPD problem. (shrink)

Central limit theorem for the functional of jump Markov process. Nguyễn Văn Hữu, Vương Quân Hoàng và Trần Minh Ngọc. Báo cáo: Hội nghị toàn quốc lần thứ III “Xác suất - Thống kê: Nghiên cứu, ứng dụng và giảng dạy” (tr. 34). Ba Vì, Hà Tây, ngày 12-14 tháng 05 năm 2005.

Some conditions are given to ensure that for a jump homogeneous Markov process $\{X(t),t\ge 0\}$ the law of the integral functional of the process $T^{-1/2} \int^T_0\varphi(X(t))dt$ converges to the normal law $N(0,\sigma^2)$ as $T\to \infty$, where $\varphi$ is a mapping from the state space $E$ into $\bbfR$.

English proficiency is increasingly crucial in Vietnam’s globalized landscape, with standardized tests like IELTS serving as key indicators of language ability. However, effectively translating international test scores to local grading systems remains a challenge. This study aimed to establish a reliable conversion method between IELTS scores and end-of-term grades for high school students in Vung Tau, Vietnam. Utilizing a quantitative, correlational design, we analyzed data from 371 students in grade 10 at Le Quy Don specialized school. Data sources included mock (...) IELTS scores administered by The Forum and official end-of-term grades. Pearson correlation and linear regression analyses were employed to examine the relationship between the variables. A significant positive correlation (r =0.432,p < 0.01) was found between IELTS scores and end-of-term grades. Linear regression analysis yielded a statistically significant model (End-of-term grade = 0.501 × IELTS + 5.843) for predicting grades based on IELTS scores. A conversion table was developed to provide a practical reference for educators. This study provides a valuable tool for bridging the gap between IELTS scores and academic performance in a Vietnamese educational context. The conversion table can inform educational decision-making regarding student placement, targeted support, and curriculum development, ultimately enhancing the understanding of English proficiency expectations for students and educators alike.

The novelty-seeking model suggests that curiosity and creativity originate from novelty processes. However, different types of novelty exist, each with distinctive relationships with memory, which potentially influence curiosity and creativity in distinct ways. We thus propose expanding the NSM model to consider these different novelty types and their specific involvement in creativity.

This article develops a discursive explanation of mixed constitution: mixed constitutional ideas and discourse generate mixed constitutional design and practice. On that base, it explores the nature, factors, and functions of the mixed constitution in Vietnam. The emergence of competing constitutional ideas (Confucian, socialist, liberal, universal) animates a constitutional discourse in which different actors adhere to different ideas. Consequently, the 2013 Constitution of Vietnam embodies a mixture of the ideas in its provisions on political institutions, economy, and especially human rights. (...) The enforcement of the constitution induces competing claims to constitutional meanings. The mixed constitution is shaped by path dependency and global diffusion of constitutional ideas. It functions as the base to constrain ideational monopoly and widen the public discourse on constitutional development. (shrink)

Most models of rational action assume that all possible states and actions are pre-defined and that preferences change only when beliefs do. But several decision and game problems lack these features, calling for a dynamic model of preferences: preferences can change when unforeseen possibilities come to light or when there is no specifiable or measurable change in belief. We propose a formally precise dynamic model of preferences that extends an existing static model. Our axioms for updating preferences preserve consistency while (...) minimising change, like Hansson’s :1–28, 1995). But unlike prior models of preference change, ours supports default reasoning with partial preference information, which is essential to handle decision problems where the decision tree isn’t surveyable. We also show that our model avoids problems for other models of preference change discussed in Spohn. (shrink)

Resumo: Após o reinado do Imperador Jiajing, da Dinastia Ming, à medida que o problema dos piratas japoneses se tornava cada vez mais grave, começaram a ser publicados livros dedicados ao estudo do Japão. Entre eles, os mais importantes são Uma Breve Pesquisa do Japão (Ri Ben Kao Lue), Uma Compilação de Mapas Japoneses (Ri Ben Tu Zuan), O Espelho do Japão (Ri Ben Yi Jian), Uma pesquisa do Japão (Ri Ben Kao), Um registro de Costumes Japoneses (Ri Ben Fen (...) Tu) Ji) e A Biografia de Piratas Japoneses em Qiantai (Qian Tai Wo Zhuan). Entre eles, O Espelho do Japão é um especial. Além disso, há também livros especiais para apresentar a situação geral do Japão, como A Coleção de Mapas Militares Costeiros (Chou Hai Tu Bian), Resistência aos Piratas Japoneses na Dinastia Ming (Huang Ming Yu Wo Lu), a Compilação de Defesa Costeira (Hai Fang Zuan Yao) e a Continuação da Categoria de Defesa Costeira nas Regiões Zhedong e Zhexi ( Liang Zhe Hai Fang Lei Kao Xu Bian). Como Zheng Shungong, autor do livro O Espelho do Japão, visitou o Japão duas vezes, muitos conteúdos do livro são baseados em sua própria experiência e conhecimento. Portanto, sua pesquisa sobre o Japão foi além da literatura semelhante da Dinastia Ming, em amplitude, profundidade e precisão. Além disso, o registro e as análises dos piratas japoneses no livro são de grande valor de pesquisa. Antes da publicação dos Anais do Japão (Ri Ben Tu Zhi), de Huang Zunxian, O Espelho do Japão era uma das monografias de mais alto nível sobre o Japão, na China antiga. (shrink)

Background: Clinical tests for detecting central and peripheral shoulder fatigue are limited. The discrimination of these two types of fatigue is necessary to better adapt recovery intervention. The Kinematic Theory of Rapid Human Movements describes the neuromotor impulse response using lognormal functions and has many applications in pathology detection. The ideal motor control is modeled and a change in the neuromuscular system is reflected in parameters extracted according to this theory. Objective: The objective of this study was to assess whether (...) a shoulder neuromuscular fatigue could be detected through parameters describing the theory, if there is the possibility to discriminate central from peripheral fatigue, and which handwriting test gives the most relevant information on fatigue. Methods: Twenty healthy participants performed two sessions of fast stroke handwriting on a tablet, before and after a shoulder fatigue. The fatigue was in internal rotation for one session and in external rotation during the other session. The drawings consisted of simple strokes, triangles, horizontal and vertical oscillations. Parameters of these strokes were extracted according to the Sigma-Lognormal model of the Kinematic Theory. The evolution of each participant was analyzed through a U-Mann-Whitney test for individual comparisons. A Hotelling’s T² test and a U-Mann-Whitney test were also performed on all participants to assess the group evolution after fatigue. Moreover, a correlation among parameters was calculated through Spearman coefficients to assess intrinsic parameters properties of each handwriting test. Results: Central and peripheral parameters were statistically different before and after fatigue with a possibility to discriminate them. Participants had various responses to fatigue. However, when considering the group, parameters related to the motor program execution showed significant increase in the handwriting tests after shoulder fatigue. The test of simple strokes permits to know more specifically where the fatigue comes from, whereas the oscillations tests were the most sensitive to fatigue. Conclusion: The results of this study suggest that the Sigma-Lognormal model of the Kinematic Theory is an innovative approach for fatigue detection with discrimination between the central and peripheral systems. Overall, there is a possibility to implement the setting for clinics and sports personalized follow-up. (shrink)

Psychosis is associated with distorted perceptions and deficient bottom-up learning such as classical fear conditioning. This has been interpreted as reflecting imprecise priors in low-level predictive coding systems. Paradoxically, overly strong beliefs, such as overvalued beliefs and delusions, are also present in psychosis-associated states. In line with this, research has suggested that patients with psychosis and associated phenotypes rely more on high-order priors to interpret perceptual input. In this behavioural and fMRI study we studied two types of fear learning, i.e., (...) instructed fear learning mediated by verbal suggestions about fear contingencies and classical fear conditioning mediated by low level associative learning, in delusion proneness—a trait in healthy individuals linked to psychotic disorders. Subjects were shown four faces out of which two were coupled with an aversive stimulation while two were not in a fear conditioning procedure. Before the conditioning, subjects were informed about the contingencies for two of the faces of each type, while no information was given for the two other faces. We could thereby study the effect of both classical fear conditioning and instructed fear learning. Our main outcome variable was evaluative rating of the faces. Simultaneously, fMRI-measurements were performed to study underlying mechanisms. We postulated that instructed fear learning, measured with evaluative ratings, is stronger in psychosis-related phenotypes, in contrast to classical fear conditioning that has repeatedly been shown to be weaker in these groups. In line with our hypothesis, we observed significantly larger instructed fear learning on a behavioural level in delusion-prone individuals compared to non-delusion-prone subjects. Instructed fear learning was associated with a bilateral activation of lateral orbitofrontal cortex that did not differ significantly between groups. However, delusion-prone subjects showed a stronger functional connectivity between right lateral orbitofrontal cortex and regions processing fear and pain. Our results suggest that psychosis-related states are associated with a strong instructed fear learning in addition to previously reported weak classical fear conditioning. Given the similarity between nocebo paradigms and instructed fear learning, our results also have an impact on understanding why nocebo effects differ between individuals. (shrink)

The article considers how the use of duplicates and the practice of photography interacted in museums of ethnography, contributing to the ambivalent framing of ethnographic objects as items that can be both scientific specimens and works of art. It focuses on the Musée d'ethnographie du Trocadéro in Paris and on the key period of its reorganization between 1928 and 1935, which was central to the institutionalization of French ethnology. By examining the place of duplicates in this museum, as well as (...) the major role attributed to photographs of objects and their materiality, the paper shows that these others of the ethnographic artefacts, often considered separately from their originals, still participated in the same project: the development of the museum and its growing cultural influence. While the duplicates positioned the museum in the various networks of the scientific community, the photographs appealed to the avant-garde, amateurs, African and Oceanian art dealers and the general public.

Prior to being a body present in time, the Other is a mountainous relief in the landscape of a common world, a perspective shape that the “I” chooses to welcome or not. This relief—if it has often been considered from the point of view of an authority deciding where It should stand—will become, we hope, the possible zone of an encounter. When this relief comes out of the ground and enters the world, when the Other becomes simultaneously something that feels (...) and is felt, its expression opens up to become a zone of contact, a mobile and permeable layer of exchange. In this surrounding zone, the Other strips and exposes itself as evanescence. It is this unattainable geometric point that inscribes an atmospheric change by its presence: tempest, thunder, earthquake, but also heat, humidity, and evaporation. The Other is an organic sounding board reflecting our modes of being together. It is this person— per-sonare—through which the world resonates, who transforms, in the same fashion, the thermal sensations into energizing transfers, into dynamic emotions. A sensorial choice is always inscribed at the threshold of an encounter. (shrink)

Vietnam is a communist country. For a Marxist ideologue, “religion is the opium of the masses.” But many communist countries—over the years—have evolved from a strictly atheistic persuasion to a tolerance for religious practices. Except probably in North Korea, this transformation from an atheistic perspective to religious tolerance has become a phenomenon in communist countries like Russia and China.Vietnam did not have that experience. This paper will show that religious pluralism was tolerated, even accepted, in communist Vietnam. I will show (...) how vibrant this religious amalgamation is in Vietnam and demonstrate, as in the case of market economics thriving in communist countries, that Vietnamese communism and religious pluralism can robustly coexist with each other.

Ultra-high-performance concrete (UHPC) is gaining popularity due to its superior mechanical properties, including high strength, toughness, durability, and excellent seismic performance. However, the risk of explosive spalling in UHPC structures exposed to fire poses a significant challenge, fundamentally hindering comprehensive studies on fire safety and limiting the broader engineering applications of UHPC. In this study, the mixture proportion of UHPC was developed and optimized by comparing the usage of yellow river and standard sands, different types of chemical admixtures, and different (...) curing regimes. Furthermore, a sensitive case study was also conducted to optimize the calcined bauxite content to improve UHPC's fire resistance. For these purposes, 189 UHPC cubes, incorporating variations in particle types, superplasticizer types, and curing regimes, were tested under three thermal levels, such as 200℃,400℃, and 600℃. The microstructural evolution of heated cube specimens was then observed using a scanning electron microscope (SEM) examination. Calcined bauxite was then considered to replace the standard sand to improve the fire resistance of UHPC and enhance the residual compressive strength of cube specimens under thermal conditions. For this purpose, 0%, 20%, 40%, 60%, 80%, and 100% calcined bauxite content was designed as six case studies. Furthermore, the degradation of UHPC strength was also investigated for the corresponding six case studies by conducting the uniaxial compressive experiments. Finally, the microstructural evolution under both thermal conditions and calcined bauxite content was observed and discussed. (shrink)

As the artificial intelligence (AI) ethics field is currently working towards its operationalisation, ethics review as carried out by research ethics committees (RECs) constitutes a powerful, but so far underdeveloped, framework to make AI ethics effective in practice at the research level. This article contributes to the elaboration of research ethics frameworks for research projects developing and/or using AI. It highlights that these frameworks are still in their infancy and in need of a structure and criteria to ensure AI research (...) projects advance in a way that respects norms and principles. This article proposes to draw from the European Union’s AI Act currently in development to shape these frameworks. Although, in the current form of the draft (as of August 2023), the obligations of the AI Act do not apply to scientific research, it is most likely that they will still have a strong impact on AI research considering the need to anticipate market placement or to test new tools in real world conditions. This article investigates what the risk-based approach in the AI Act implies for research ethics and highlights some AI Act obligations of particular value to implement for ethics review processes.

This article addresses the problem of automatically extracting legal indices which express the important contents of legal documents. Legal indices are not limited to single-word keywords and compound-word keywords, they are also clause keywords. We approach index extraction using structural information of Japanese sentences, i.e. chunks and clauses. Based on the assumption that legal indices are composed of important tokens from the documents, extracting legal indices is treated as a problem of collecting chunks and clauses that contain as many important (...) tokens as possible. Each token is assigned a weight which is a statistical score, e.g. TF–IDF and Okapi BM25, to indicate its importance. The importance of a chunk or clause is determined based on the average weight of tokens included in that chunk or clause. Then, highly weighted chunks and clauses are recognized as the indices for legal documents. The experimental results on Japanese National Pension Act data show that our proposed method achieves better performance than TextRank, the most popular unsupervised method in extracting single-word and compound-word keywords. In addition, this approach is also applicable to extract clause keywords with high performance. (shrink)
