基于语义模型的Web挖掘算法研究

Web mining algorithm based on semantic model

分析了Web日志和用户查询行为之间存在的潜在语义关系,提出了一个能够有效反映用户查询行为的语义模型.提出了一个Web挖掘算法.由于Web日志是一个典型的稀疏矩阵,进一步给出了加速的Web挖掘算法.实验结果表明,基于语义模型的Web挖掘算法是可行、有效的.

A semantic model reflecting the relationship among users,queries and resources is proposed based on the analysis on rations between Web logs and user queries. And then a Web usage mining algorithm is presented. In view of Web related information with property of sparsity,the algorithm is speeded up by adjusting the orders of multiplication. Experiments show that the proposed method is feasible and effective.
