Proposes a completely agent-based approach for information gathering on information networks with a large number of distributed heterogeneous sources, such as Internet. Locating and accessing information in such a large distributed system which changes dynamically is challenging. An agent-based solution is the most suitable in such situations. We first review the drawbacks of existing non-agent and partially agent-based solutions for locating information on Internet. We introduce a CAS model to express a Society of Cooperative Agents and then explain how our completely agent based solution based on the proposed CAS model overcomes the weak points of existing approaches.
