The Design and Optimization of an Active Pushing System Based on the Vector Space Model
基于向量空间模型的主动推送系统设计与优化

The active information service is one of the trend of information retrieval service. Though the traditional vector space model has some advantages in the design of active pushing system, it can' t solve the irrelevant problem. The paper provides some improving measures, and gives a model of active pushing system based on vector space model, which can better improve the efficiency of Web information retrieval.
