Web Services Filtrate Technologies Based on Latent Semantic Analysis
Hongtao Guo · Jisuanji gongcheng · 2008
The available services discovery mechanisms have lower matching efficiency and precision because of lacking services filtrate mechanism and matching the services basic attributes,quality of services attributes by keywords.This paper puts forward a Web services filtrate method based on Latent Semantic Analysis(LSA).This method describes Web services basic attributes,quality attributes using tree structure,uses certain terms-frequency statistic method and weights method to build latent semantic analysis space,and builts advertising services index database and filtrates the Web services according to services request.Experimental results prove that this algorithm has higher precision and recall and improves services matching efficiency largely.
