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档和电影的全文检索系统。该系统首先从庞大的演示文档中检索出适合用户查询的页面，然后将页面内容和相应的演示电影场景用语音同时提供给用户.演示文档和演示影片处理模块的开发该系统能够以80%的准确率指定演示影片的各个演示页面和剪切场景的对应关系。然而，我们可以发现，当演示影片包含动画幻灯片时，准确性变低.电影场景与语言信息链接模块的开发本系统能够从演示文档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场景的时间信息进行链接.演讲视频的收集我们收集了近100个演讲文档和视频，几乎都是我们实验室成员的毕业和硕士论文演讲。大型演示文稿全文检索系统的管理开发了大型演示文稿全文检索系统。大约100个演示文稿和电影已注册到这个系统。本研究发表论文情况本研究已发表的论文如下：期刊论文6篇（英文1篇，日文5篇），国际会议论文7篇，国内会议论文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.
