This paper gives the types and characteristics of intelligent information push and pull technology (IIPP) and build a push and pull model. It presents the design and implementation of an active information service system based on IIPP technology and draws the flow diagram of system development process. The system collects data from network according to the analysis method which combines interest model with credibility model. The system is developed by applying C#.NET programming language and AJAX technology. The system achieves the goal of balancing the user interest requirements and data credibility.
