It has become very important for advanced organizations to make the best use of information gathered from database in companies and from the Internet. There are three stages in the information life cycle; Finding, Organizing and Sharing. Many technologies have been developed for the finding stage. On the other hand, no concrete organizing and sharing technologies exist to manage the information found. In this paper, we focus on the management of information sharing among group members. We propose to use a semantic-network for organizing information that has been gathered. We show an example of how to manage URL information in order to share it among small groups. As the system is under development, only a partial evaluation of the method is given.
