摘要
利用数据压缩原理,对文本文档进行压缩,由压缩比公式得到相似值.与基于统计的传统方法相比,它具有简便快速的特点.
In the process of information retrieval, the traditional method is to compute similarity between texts. The coefficient similitude figures the degree of compatibility. There are two main methods: Correlation coefficient and Cosine. We base on the theory of Data Compression and use the compression ratio to (express) the similarity between texts. It has some advantages over the others.
