Vivisimo receives patent for search technology
Vivisimo Inc., a Squirrel Hill technology company, said on Tuesday it received a patent for search technology it developed.
The company, formed in 2000 by a Carnegie Mellon University computer science researcher, was awarded the patent by the Patent and Trademark Office for "remix clustering," a technology that groups together search results into clusters of information and allows searchers to remix the cluster categories that are offered to mine results more deeply, the company said. Remix clustering builds on the company's original clustering technology and is the main feature of its Velocity software for large companies and organizations.
In recent years, the company changed its focus from public search engines to search for businesses. The company's Clusty.com search engine, which was a small part of its business, was sold in May 2010 to Yippy Inc. of Fort Myers, Fla., for $5.6 million.
