PC上での網羅的な履歴による過去の活動全体の再構成と問題解決への履歴利用の可能性

抄録

In this paper, the authors have implemented an experimental history utilization system which support to retrieve useful information for user's problem solving by inspecting the entire activity log on PC and reading the implication of the activity, and have shown the potential of various usage of history. That is the feature to handle the history of entire activity with keeping the bundle of activity, not to handle the daily problem solving partially. By using such exhaustive history, the users could use the relevancy in explicit way, And it become possible to utilize the history of past activity more than using information as is recorded. Actually, the authors have developed the experimental system to record the exhaustive history by screenshots and inspecting and reading that. As a result, although the users did not utilize the system as often as the authors expected, it became possible to utilize each information fragments that was not recorded explicitly in usual way and the relevancy of them by reading the activity bundle. It was also shown that the potential of extracting and utilizing the information of past activity that was not recorded explicitly from the current point of view. And in the experiment process, the potency of obtaining useful knowledge by sharing the entire activity with others have been indicated.
