Development of the Full Text Search System for Presentation Movies Using the Video Processing Technology

本研究的目的是开发演示文稿和电影的全文搜索系统。该系统首先从庞大的演示文稿文档中检索出适合用户查询的页面，然后将页面的内容和相应的演示电影场景以语音的形式提供给用户。演示文稿和演示影片处理模块的开发本系统可以指定演示文稿页面与演示影片剪辑场景的对应关系，准确率达到80%。然而，我们可以发现，当演示电影包括动画幻灯片时，准确率变得较低。开发了电影场景与语言信息的链接模块，该系统可以从演示文稿中提取词频和词位作为语言信息，并将语言信息与相应剪辑的时间信息联系起来。演示影片集我们收集了大约100份演示文件和影片，几乎都是我们实验室成员的毕业报告和硕士论文演示。大型演示文稿和电影全文检索系统的管理已开发出大型演示文稿和电影全文检索系统。约有100份演示文稿和电影已登记到该系统中。目前已发表的论文有：期刊6篇(英文1篇，日文5篇)，国际会议7篇，国内学术会议25篇。

The purpose of this research is the development of the full text search system for presentation documents and movies. This system first retrieves the suitable page for the user's query from the huge presentation documents, and then this system serves both the contents of the page and the corresponding presentation movie scene with the voice.1. The development of the processing module for presentation document and movieThis system can specify the correspondence of each presentation page and the cut scene of the presentation movie by the accuracy of 80%. We can found, however, that the accuracy becomes low when the presentation movie includes the animation slide.2. The development of the linking module for movie scenes and language informationThis system can extract word frequency and word position as the linguistic information from the presentation document, and link the linguistic information with time information of the corresponding cut wene.3. The collection of presentation moviesWe collected about 100 presentation documents and movies, which are almost graduation and master thesis presentations of our laboratory members.4. The Management of the large-scale full text retrieval system for presentation documents and moviesThe large-wale full text retrieval system for presentation documents and movies has been developed. About 100 presentation documents and movies have been registered into this system.5. Publications of this researchThe papers about this research have been already published as the following:The number of journal is 6 papers(1 paper is in English, and 5 papers are in Japanese)The number of international conference is 7 papers.The number of domestic oonference is 25 papers.
