Hakia, a natural language search engine that uses semantic analysis of the Web, recently launched a new initiative with librarians to identify "credible" content on the Web. The program is designed to provide searchers with a quick way to access lists of sites that they know professionals have vetted as an alternative to the list of all-Web results that search engines typically provide. Hakia is the first search engine to integrate librarians' collective knowledge of credible Web sites into search results to guide searchers. Hakia's credible sites program initially covers health and environmental Web sites, although it hopes to expand to all topics. Hakia isn't the only search engine that realizes that the Web contains a wealth of inaccurate as well as accurate information and that searchers can benefit from vetted results.
