Development of a system for dynamically collecting information distributed on the Web using workflow and extraction of difference information

我们研究了一个有效利用分布在Web上的知识信息的系统。我们的系统使用工作流来导航用户收集信息，并从包含重复信息的网页中提取附加信息。在三年的研究期间，我们开发了一些Web上的子系统，并验证了它们的有效性。它们是支持参加国际会议、提高个人项目工作能力、帮助利用搜索历史检索信息、自动收集关于公民团体志愿活动地点的信息等的系统。

We studied a system to make an effective use of knowledge information distributed on the Web. Our system navigates users using workflow to collect information, and extract additional information from Web pages containing duplicate one. We developed some subsystems on the Web and confirmed their effectiveness during the three year study period. They are systems to support participation in international conferences, to enhance individual project work ability, to help information retrieval using search history, to automatically collect information about locations of volunteer activities of citizen groups, etc.
