ClusterMed is a free demo that uses the Vivisimo Velocity Search Platform to organize PubMed's extensive inventory of medical research articles into dynamic categories that help users easily navigate search results. Pubmed is a free search engine that offers access to the Medline database of citations and abstracts of biomedical research articles. It is offered by the U.S. National Library of Medicine.

ClusterMed now allows users to search in a highly intuitive and personalized manner. The Velocity Clustering Engine allows end users to view results organized, or clustered, by topic, author, mesh headings and date. This resource helps regular Pubmed users reduce research time, improve research effectiveness and quickly view an overview on a new or peripheral research area. To view the benefits of ClusterMed try the search query chicken pox, avian flu or baseball.
