Agent-based approach for information gathering on highly distributed and heterogeneous environment

The core of the problem of Information Gathering is how to generate a concise, high-quality response to the information needs of a user. However, this task is becoming difficult due to the explosion in the amount of electronic information. Agent-based solutions have become an popular approach for locating information in an growing distributed heterogeneous environment like Internet. We first survey the existing non-agent and partially agent-based solutions; then to overcome their drawbacks we propose a completely agent-based solutions, when the different types of agents introduced-named user agent, machine agent, manager-cooperate to decrease user load and gain efficiency in the retrieval process.
