Vivisimo, a provider of search software and expertise, announced a new patent-pending technology--remix clustering--designed to help users find new topics and gain insights related to their search queries. Vivisimo's standard clustering organizes search results into topical folders on the fly, without any pre-processing of source documents. Clustering gives a quick overview of the main topics, enables easy access to valuable but low-ranked search results, and groups together related documents for joint consideration.
Vivisimo's Remix clustering works like this: The user first sees clustered results in the usual style. Then, a single click on Remix reveals submerged or secondary topics that were not generated in the initial clustering. It works by feedback: cluster the same search results again, but explicitly ignore the topics that the user already saw.
