| Research Abstract |
We analyzed use of the users' search history, paying attention to users' information search process. As a result, it was effective that the search history is expressed visually in consideration of a time series and is shown by a tree structure. Moreover, we build a shared history system for the books that can represent user preference using Nippon Decimal Classification. As a result of the experiment, it turned out that our system can recommend persons useful for the user with accuracy more sufficient than the conventional techniques, such as a vector space method.
