In this paper, we propose a system that starts with the searching result of user's query and continuously offers new keywords related to the query. The primary purpose of the proposed system is to help users find information that the users cannot explain clearly. The proposed system obtains useful information by connecting different information sources, represents the information under an integrated schema, and offers a cross searching environment. In addition, it presents a visualized diagram that shows relations between keywords so that users can easily find the desired information. Therefore users can find information easily in an envirionment that is not limited to a certain site.
