| Abstract: | With the rapid development of the network, the exploding volume of digital information makes it very difficult for users to use. Then, the researches focus on the information filtering technology, which can reduce the users' burden in the course of obtaining the network information. The paper analyzes content-based systems. Firstly, the paper introduces three filtering model--Boolean model, Vector Space model and probability, analyzes their strengths and weaknesses. After that, the paper introduces the design and development of Web Sites Search system. |
