About Information Agents:

• An information agent is a computational software entity (an intelligent agent) that may access one or multiple, distributed, and heterogeneous information sources available and proactively acquires, mediates and maintains relevant information on behalf of its users.
• Information agents are supposed to cope with the difficulties associated with the information overload of the user.
• This implies their ability to semantically broker information by:
  • providing a pro-active resource discovery;
  • resolving the information impedance of information consumers and providers;
  • offering value-added information services and products to the user or other agents.
• The information sources may be of many types, including, for example, traditional databases as well as other information agents.
