Surf Canyon Logo
Surf Canyon

Using semantic real-time implicit personalization, Surf Canyon develops Discovery for Search. This patent-pending technology is embedded in a browser extension that can work with virtually any third-party search engine, and assists users in finding relevant information that's buried within the often overwhelming amount of search results. As the quantity of information on the internet expands exponentially, it is becoming increasingly difficult for search engines to provide relevant results on a page, especially when users continue to enter two- and three-word queries. Furthermore, providing millions of matched documents is of little use when few people venture past a page. A method for disambiguating intent post-query is therefore essential.
