Because of the information flood on the Web, it has become difficult to search necessary information. Although Web search engines assign authority values to Web pages and show ranked results, it is not enough to find information of interest easily, as users have to comb through reliable but out of the focus information. In this situation, personalization of Web search results is effective. To realize the personalization, a user profiling technique is essential, however, since the users’ interests are not stable and are versatile, it should be flexible and tolerant to change of the environment. In this paper, we propose a user profiling method based on the model of the organisms’ flexibility and environmental tolerance. We review the previous user profiling methods and discuss the adequacy of applying this model to user profiling.
