摘要
为了将关联规则挖掘技术更好地应用于信息检索查询扩展,通过对基于关联规则挖掘的查询扩展模型的深入研究,归纳出4类共13种查询扩展模型,理论分析和实验比较各个查询扩展模型的检索性能,试图发现一些优秀的扩展模型。
In order to better apply association rule mining technique to query expansion and find out some better query expansion models, 4 categories of query expansion models with 13 varieties are given based on item -all - weighted association rule mining. Comparison of retrieval performances are made through experiments. Some better query expansion models are discovered.
