Exalead, a global provider of search software for business and the web, has added a new Wikipedia search application to its exalead one:search platform, the technology foundation for Exalead's product portfolio--from the desktop to the enterprise and the web. Users of Exalead's web search engine can search, browse, and navigate the Wikipedia database by making use of the company's new vertical search capability that has been added to the exalead one:search technology platform. The Wikipedia search application can be launched by clicking a Wikipedia tab on the Exalead search engine's home page. The exalead one:search platform has leveraged entity extraction to automatically return a list of related topics and categories based on the original search query. With the integration of topic maps, all related terms and categories will be presented in the form of a tag cloud. Users can then click on a word in the cloud to refine the query.
