To share information more effectively in a laboratory, this study develops a method to collect and visualize research documents as well as research activities efficiently without exception. First, this paper introduces a research information relation graph that reflects research activities that obtain information. Furthermore, this paper makes research(More)
Skillful management of the various types of documents used in intelligent activities and their efficient utilization are important. However, most available systems target only a single type of document (e-mails, Web pages, etc.) or are not adaptive enough. A more promising approach is topic-centered document management. A topic-centered document management(More)
Discussion using e-mail is frequently conducted in intelligent works such as research activity. It is important but generally difficult to successfully grasp the processes of the discussions and their results. There exist descriptions of diverse particle sizes in actual discussion using e-mail. This feature brings about the difficulty in grasping the(More)
Opportunities of continuous Web exploration with trial and error have been increased in intellectual creative activities such as research work and PBL. However, it is often difficult to pick up useful pages. In such exploration, information that a user particularly needs and his/her viewpoints changes in accordance with progress of the work and trial and(More)
This research was aimed at developing methods for estimating error factors in programming exercises so that professors could effectively guide students based on an understanding of stumbling by novice students. We first developed a method for simultaneously estimating compilation, logic errors by using case-bases. Moreover, we developed a mechanism for(More)
Skillful management of the various types of documents used in intelligent activities and their efficient utilization are undoubtedly important. However, most available methods and systems target only a single type of document (e-mails, Web pages, etc.) or are not adaptive enough. A more promising approach is topic-centered document management. In this(More)
