Pittsburgh, Pennsylvania - November 30, 2005 - Search engine software technology company, Vivisimo has announced the Beta launch of Clusty.jp, a public showcase of the company's novel development of a Japanese-language Clustering Search Engine modeled on Clusty.com.

Clusty.jp ( http://clusty.jp ) combines custom crawls of Japanese news sites, including Asahi, Nikkei, and Yomiuri and the Japanese Wikipedia, as well as meta-search of top-quality, World Wide Web crawlers. The combined search results are clustered into topic folders that enable Japanese Web searchers to more effectively navigate results, uncover major themes and easily find lower-ranked, but highly relevant search results.

According to Raul Valdes-Perez, CEO of Vivisimo, ''As the second largest IT market in the world, Japan represents an exciting market opportunity for us. Until today, Japan did not have access to the benefits of clustering search engines on the Web and within enterprises.''

Vivisimo serves enterprise customers through its Velocity suite of clustering, search and meta-search products. Instead of long lists of results, users are presented with results organized into categories without incurring the cost and complexity of taxonomy-building. Incorporating Vivisimo's award-winning Clustering Engine, Velocity delivers a superior search experience, unmatched implementation flexibility and increased productivity.

Vincent Thomas, Senior Director of Business Development for Asia-Pacific at Vivisimo added, ''The launch of Clusty.jp heralds the availability of Vivisimo's search and clustering products for Japanese Web properties, mobile services and enterprises. This will lead to more productive search experiences for employees, customers and the broad consumer public.''
