“…The RDF is a W3C recommendation for the Semantic Web [19]. While RDF has traditionally been used for web pages, it has also found or personalized applications in areas such as device information [20], [21] and content metadata [22], [23]. Similarly, we propose RDF data to describe individually adaptable subtitles and captions.…”

Subtitles and closed captions, originally intended for individuals with hearing impairments, have gained widespread usage among non-hearing-impaired individuals. This study focuses on adapting subtitles and captions, particularly the incorporation of the kanji ruby, for non-hearing-impaired users. Our study investigated the necessity of kanji ruby by subjecting non-hearing-impaired adults to audio content through experiments employing Welch's t-test. Additionally, we proposed and evaluated an adaptive model for determining whether ruby should be added to kanji captions based on the experimental outcomes. The results indicate that optimizing kanji ruby requires considering not only the difficulty of the kanji characters and the user's proficiency but also the audio content.

“…4.1 Evaluation of the Method Used to Extract Basic/ Advanced Relationships When extracting the basic/advanced relationships among terms, we adjusted the number of important terms extracted in order to optimize our method [16]. For the teaching documents, we used the Study Notes provided as supplementary material in NHK's High School Courses.…”

With a range of learning platforms available on the Internet and the increasing use of video content in education, there have been many studies on using ontologies to support education and learning. However, in many cases, the connections among content systematized in this way are confined within a subject, and there is no learning across subjects or expansion of learners' interests beyond individual subjects. We aimed to connect all educational content in a way that goes beyond school subjects and curricula. In this study, we re-examined the learning sequence of subject matter terms over the course of the learning process, redefined it as a set of basic/advanced relationships among the terms, and proposed a method of estimating the appropriate ordering of content for learning by structuring and utilizing this terminological attribute. We also prototyped a system incorporating our proposed method to help users select educational content and tested it in a proof-of-concept experiment. By comparing the textbook-based presentation of related content with our proposed cross-subject presentation, we identified each method's characteristics and confirmed the proposed method's effectiveness at expanding learners' interests.
