Abstract(in English) | In recent years, people have more opportunities to gather information using the Internet. But user can't get information as a user intends or user can't grasp current topics because the result is enormous and overlap. This paper classifies search results in every topic by Document Clustering and uses Non-negative Matrix Factorization (NMF) in Document Clustering. Unfortunately NFM needs the number of clusters before calculation and gives many answers. As a solution for this problem, this paper proposes that resolution is repeated and cluster evaluate using association between document and cluster degree and between word and cluster degree. |
