Mining user's behavior using "crisp and fuzzy bags": a new perspective and new findings

In all studies of user's behavior on searching the Web, researchers found that their search strategy or traversal process showed a pattern of moving back and forth between searching and browsing. The moving back and forth, including backtracking to a former Web page, constitute the measurable or physical states or actions that a user takes while searching the Web. The structure of a bag as a framework can help study the behavior of users and uncover some intrinsic properties about users. This study applies bags to user's mining of the Web.
