基于HowNet查询扩展方法的探究
RESEARCH ON QUERY EXPANSION METHOD BASED ON HOWNET
摘要
Abstract
Considering that query expansion method seldom considers the order of words, the distribution and the conceptual relationship of terms in information retrieval,it is difficult for us to make a full measure of text similarity in information retrieval.In view of this situation, we measured the concept relatedness using the factors such as order of words, word distance and the weight of extended words based on the external knowledge resource HowNet.We incorporated above concept relatedness into the retrieval procedure of Lucene, realizing an improved feature quantification method.Experiments on Top-N search results showed that the overall performance of the system was effectively improved by the method adopted in this paper.关键词
