Grey Relational Analysis for Query Expansion

摘要：

　　For one-sidedness of the various qualitative expansion meth ods, we propose a query terms selection method based on Grey Relational Analysis (GRA).We called the fusion expansion technique with GRA (FET-GRA).It calculates weight of expansion term by varied qualita tive expansions and comprehensive weight by FET-GRA and thus ex tracts expansion term in terms of the weight.The experiment result of TREC dataset shows the method (FET-GRA) is substantially superior to TF-IDF, Mutual Information , Local Context Analysis.
