Since much information is available in the Internet, there is more difficult tofind out a relevant information. For many Internet users, search engine cannot solve this problem.Clustering engines that apply of cluster analysis provide an alternative way to find out the relevantinformation among the much information that scattered around the Internet. Vivisimo is a clusteringengine that clusters documents have been indexed by many search engines. Based on the user’s query,Vivisimo does a meta-search to the indexing results of many search engines. The results of meta-searchare clustered to many clusters, which labeled using dominant characteristic of the cluster, and thendisplayed for the users. The clusters that were formed can help users with guidance to browsing and make an interpretation or relevant judgement the searching results. Therefore, it can be said that clusteringengine give a benefit for user to find out the relevant information in the Internet. On the other hand,search engines can give more comprehensives searching results. So, the clustering engine and searchengines can be used complementary in the successive searching to get easier searching withcomprehensive results.Miswan*; Mustangimah**; * Mahasiswa Program Studi Ilmu Informasi, Perpustakaan, dan Kearsipan; Program Pascasarjana, Universitas Indonesia ** Pusat Pengembangan Teknologi Informasi dan Komputasi - BATAN
