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)
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)
Many researchers progress the research with preparing presentation slides and papers in parallel. However, their management becomes complicated in accordance with research progresses since a number of things to be described increases more and more. As a result, it is troublesome for researchers to investigate the contents of presentation slides and papers(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)
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)
Opportunities for Web exploration have been remarkably increased. In particular, complicated Web search with a stack of search and acquisitions of Web pages is significant in long-term intellectual activity. In such exploration, it is important to identify the noteworthy pages and their relationships in increasing bookmark in accordance with change of(More)
