With the spread of Internet, the number of users and hosts has been increased exponentially. Also, newly emerging services try to provide users with more enhanced Quality of Service (QoS). The increase of users and hosts and the enhancement of QoS have caused a radical increase of Internet traffic. As a result, it is very difficult for users to find required information and the information location. In this paper, we propose a matchmaking recruiting system over the Internet. Our system is based on agent technology. The agent carries out the matchmaking using a knowledge base the same as the human beings. By using the agent, the proposed system is able to get the best matching data and decreases the Internet load.
