Abstract

ブロードバンド,デジタル放送およびインターネットの普及と発達にともなって,放送と通信の融合が着々と進んでいる.これらのメディア間の情報統合,相互補完によって,ユーザがより多様なコンテンツにアクセスすることが可能となる.本論文では,放送とWebコンテンツの動的統合のためのQuery-Free検索機構を提案する.Query-Free検索機構は,単なる類似検索ではなく,放送番組の内容を補完するWebページの検索が可能である.そのための,1)話題構造と話題構造によるコンテンツ結合モデルと,2)字幕データのようなテキストストリームのセグメンテーションと話題構造の抽出手法を提案する.さらに,実験とその結果について述べ,提案手法の検証を行う.With the spreading of digital broadcasting and broadband internet connection services, the infrastructure for integration of TV-programs and the Internet is prepared. It is to say that it becomes possible to acquire interesting information from different media at the same time to improve the quality and detailedness of information. In this paper, at first, we propose a novel content-based join model for data streams (closed captions of videos or TV-programs) and web pages based on a notion called topic structure. Based on this model, we propose a query-free web retrieval mechanism by using topic structures of a video. One of the notable features of query-free retrieval mechanism is that the retrieved information is not just similar to the video, but also provides some additional information. We also show some experiment results in this paper.
