We propose an idea called ``ontology reuse'' to develop ontology (or taxonomy) for information search more easily by its development cost reduction. For its feasibility demonstration, we developed a prototype system that converts taxonomy information of web contents to RDF format, collects it into a server and visualizes taxonomy infomation as a 2D map for editing itself and searching information. And our goal is to realize ``ontology circulation'', which means that ontology information flows freely and easily over the Internet and (...) an intranet. (shrink)

Artificial intelligence (AI) has become indispensable in our lives. The development of a quantitative scale for AI ethics is necessary for a better understanding of public attitudes toward AI research ethics and to advance the discussion on using AI within society. For this study, we developed an AI ethics scale based on AI-specific scenarios. We investigated public attitudes toward AI ethics in Japan and the US using online questionnaires. We designed a test set using four dilemma scenarios and questionnaire items (...) based on a theoretical framework for ethics, legal, and social issues (ELSI). We found that _country_ and _age_ are the most informative sociodemographic categories for predicting attitudes for AI ethics. Our proposed scale, which consists of 13 questions, can be reduced to only three, covering ethics, tradition, and policies. This new AI ethics scale will help to quantify how AI research is accepted in society and which area of ELSI people are most concerned with. (shrink)

Recent technological advances have accelerated the use of artificial intelligence (AI) in the world. Public concerns over AI in ethical, legal, and social issues (ELSI) may have been enhanced, but their awareness has not been fully examined between countries and cultures. We created four scenarios regarding the use of AI: “voice,” “recruiting,” “face,” and “immigration,” and compared public concerns in Japan, the US, Germany, and the Republic of Korea (hereafter Korea). Additionally, public ELSI concerns in respect of AI were measured (...) using four items: ethics, tradition, law and social benefit. Respondents with AI knowledge tended to exhibit stronger concern about ELSI in various situations. In terms of law concerns, Japanese respondents displayed greater concerns. In contrast, the US, when compared Japan, expressed a relatively optimistic view of the current law landscape. Regarding social benefits, Korea, compared to Japan, exhibited a more positive outlook, whereas Germany, in comparison to Japan, expressed heightened concerns about it across different scenarios.
