The growth of the Internet has led to an information overload. Agents are required to filter and sort out this information into manageable volumes. Agents can be used to automate several of the repetitive, time consuming and mundane tasks. This would reduce costs and increase productivity. Through agent technology we can construct expert system to solve the problem in specific areas where expertise is costly or rare.
Agents can provide increased support to the knowledge workers in the sphere of decision making.
So far, people have done much work on multi-agent and intelligent agent. There are many platforms for multi-agent system and intelligent agent. We construct a Multi-agent environment MAGE that is a common software platform for agent. The MAGE is written in Java and is a powerful tool to construct multi-agent systems for Internet applications. There are two kinds of agent, facilitator and Web spiders.
