Proprietary Search Engine - Sogou.com

Sogou, which means “Search Dog”, is Sohu’s proprietary search engine launched in August 2004. Sogou performs interactive searches of billions of Web pages using advanced algorithms. The user is taken through a fast and convenient interactive process to arrive at the most relevant selection of the integrated Website and page search results. On February 25, 2005, we launched our upgraded search engine Sogou 2.0 with an expanded breadth of one billion Chinese language indexed web pages, higher updating speed and shorter search time. In November 2005, we announced the launch of Sogou version 2.5, a further upgrade for our proprietary search engine. This upgraded Sogou 2.5 was more sophisticated with advanced spider technology and more intelligent in terms of crawling, selecting and ranking capabilities so as to provide more relevant, accurate and up-to-date Web search results. On January 1, 2007, we announced the launch of Sogou 3.0, a newly upgraded version for our intelligent search engine. This new version of Sogou can provide our users with higher updating speeds, shortened search times and more accurate search results based on an expanded database capacity of more than ten billion retrieved pages. We intend to integrate Sogou 3.0 with the content strength of our comprehensive Internet platform and our community based product offering, which will enable us to obtain knowledge of our users’ online habits and interests, in order to optimize the overall search experience for our users.
