一种基于潜在语义分析的查询扩展算法

A Latent Semantic Analysis Based Algorithm for Query Expansion

该文提出一种新的查询扩展算法。通过对文本进行潜在语义分析,引入计算词语间语义相似度的方法,将文本聚类应用到检索的交互过程中,以提高信息检索的质量。实验结果表明该算法对于提高检索的准确率是十分有效的。

This paper proposes a new algorithm for query expansion.In order to improve the quality of information re-trieval,the approaches for latent semantic analysis,measuring semantic similarity between words and text clustering are used in the algorithm.The experimental results show that the new algorithm can help improve the retrieval performance significantly.
