Exalead, a provider of search software for business and the web, has announced the addition of a new Wikipedia search application in 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, the first in a series of vertical search functions from Exalead, can be launched by clicking a Wikipedia tab on the Exalead search engine's home page. 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.
