Rough-set-based K-means Clustering Algorithm in Case Retrieval
Dong Wang · 2010
The retrieval efficiency will fall down due to the increasing numbers of cases in Database in marketing Onto-logy based case retrieval system.How to effectively improve the efficiency of case retrieval system is a serious problem.A K-means clustering algorithm based on rough set was proposed which can do the clustering work on thousands of marketing cases in Case Retrieval System in order to figure out the center of each cluster.So there is no need to do the similarity work in terms of each case.It is improved through experiment that the methods can largely enhance the performance of case retrieval system.
