Studies on a Multimedia Minutes System by Effectively Utilizing Context-Aware Technology

1)情境感知系统基础设施的研究与开发我们研究并开发了一个用于管理组织活动中产生的各种内容的系统。为了创建和展示会议内容，有必要了解组织成员的情况和/或小组情况。因此，我们考虑了一种通过使用用户上下文信息来了解成员在会议中的情况的方法。具体地说，该系统利用IC标签和传感器信息来了解会议和用户状态，并自动记录和组织会议内容以显示给用户。我们利用无源RFID标签开发了一个具有群在场功能的原型系统，并对其有效性进行了评估。此外，我们还设计了一个利用Active RDIF-…自动生成动态群组出席信息的系统。2)协作会议纪要系统的研究通过分析系统日志和运行两年的调查问卷，共同制作了More lLabMinents会议纪要系统。在结果中，我们不仅可以看到记录内容的数量增加，而且还可以看到质量的提高。此外，使用我们的方法，我们可以减少40%以上的劳动力。3)基于演示的协同会议标注系统的研究我们开发了一个协同标注系统ColLabSticky，用于收集会议中用户对演示幻灯片的评论。很难收集演示文稿中的评论，因为参与者需要花费很多时间来理解演示文稿。然后，我们将重点放在阅读书籍上做标记或写备忘录的行为上，并考虑通过在演示幻灯片中粘贴标签来促进发表适当的评论。在评价结果上，该系统比传统的会议评论收集系统(如聊天系统)能够收集更多的用户评论。4)企业内部博客词条推荐系统的研究我们考虑并开发了一个支持动态变化用户兴趣的企业内部博客词条推荐系统。为了向用户推荐合适的词条，我们将用户的兴趣分为长跨度兴趣和短跨度兴趣。通过使用这些分类的兴趣，我们的系统能够根据用户的兴趣推荐合适的条目。较少

1) Research and Development of Context-Aware System InfrastructureWe have investigated and developed a system for managing various kinds of contents which are generated in organization activities. It is necessary to understand organization members' situations and/or group situations for creating and showing meeting contents. Therefore, we have considered a method for understanding members' situations in a meeting by using user contexts information. Specifically, this system understands meeting and user status by using IC-Tags and sensor information, and automatically records and organizes the meeting contents to be showed to users. We have developed a prototype system with the group-presence function which is a basic technology in this system by using passive RFID-Tags, and evaluated its validity. Moreover we have designed a system for automatically creating dynamic group-presence information by using active RDIF-Tags.2) Study of Collaborative Meeting Minutes SystemWe have evaluated Co … More llabMinutes, a meeting minutes system produced collaboratively, by analyzing system logs and questionnaires for two years operation. In results, we can find not only quantitative increase, but also qualitative improvement in the recorded contents. In addition, we can reduce labor more than 40 percent by using our method. Furthermore, we can find the recording speed of our method catches up with speaking speed.3) Study of Collaborative Meeting Annotation System Using PresentationWe have developed a system of collaborative annotation system CollabSticky for collecting users' comments to presentation slides in a meeting. It is hard to collect the comments in presentation, because it takes much time for the participants to understand the presentation. Then we focus on acts of putting marks or writing memos in reading books, and we consider promoting posting appropriate comments by sticking tags in the presentation slides. In results of evaluation, this system enable to collect many users' comments more than conventional meeting comment collecting systems such as a chat system.4) Study of Entry Recommendation System in Intranet-blogWe have considered and developed an entry recommendation system supporting dynamically changing users' interests in intranet-blog. For recommending right entries to users, we have categorized the users' interests to long-span interests and short-span interests. By using these classified interests, our system enables to recommend appropriate entries corresponding to the users' interests. Less
