However, self-learners retrieving such files still need support to decide which files are worth learning because it can be difficult to understand the context of each file. In this paper, we introduce a quick browsing system to help a user effectively decide whether a presentation content is appropriate for his\/her specific learning needs. Our method provides context-based word clouds that summarize slide information to help the user visually understand the context of a presentation content. In our method, words important to the &amp;ldquo;presentation context,&amp;rdquo; that is, the relevant information on the slides, are first extracted based on components of the presentation content (i.e., intra-slide structure and inter-slide structure). Then the word cloud is generated by weighting the words within the presentation context for each slide. Finally, the word clouds are interactively presented with visual effects that reflect their semantic meanings.<\/jats:p>","DOI":"10.3233\/978-1-61499-262-2-108","type":"book-chapter","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T11:58:24Z","timestamp":1740398304000},"source":"Crossref","is-referenced-by-count":1,"title":["Dynamic Word Clouds: Context-based Word Clouds of Presentation Slides for Quick Browsing"],"prefix":"10.3233","author":[{"family":"Wang Yuanyuan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Sumiya Kazutoshi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","Intelligent Interactive Multimedia Systems and Services"],"original-title":[],"deposited":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T12:22:09Z","timestamp":1740399729000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=254&spage=108"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-262-2-108","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2013]]}}}
