    SHANGHAI, China, June 30 /Xinhua-PRNewswire/ -- SINA Corporation
 (Nasdaq:   SINA), a leading online media company and value-added information
 service provider for China and for global Chinese communities, today announced
 that it has launched its self-developed algorithmic search engine, ''iAsk.''
 After one year of intensive self-development, iAsk represents a break through
 in online search technology by combining the conventional web search algorithm
 method with SINA's own differentiated indexing technology.  Leveraging SINA's
 existing diverse portfolio of online portal and mobile resources, iAsk intends
 to provide Chinese Netizens with the most comprehensive and relevant search
     iAsk, offers knowledge-based and community-based search in addition to the
 standard web-based search.  While maintaining the power of traditional
 algorithm technology, SINA iAsk offers an added bonus of users' interactivity
 with a unique Q&A platform.  iAsk categorizes search subjects into areas of
 news, pictures, music, knowledge, and video and allows users to input key
 words and questions of their interests.  iAsk then ranks sites partly by
 subject-specific popularity, clusters results into subject groups, and lists
 related link collections by experts.  SINA iAsk also features an ''express
 zone'' that filters all past information and data collected by SINA on the
 subject being searched.  In addition, SINA iAsk offers personalized features
 such as search by local content (maps, entertainment and travel) and archival
 of personal favorites.  iAsk is designed to work with both the Chinese and
 English language queries.
     ''As China's largest online portal, we are well positioned to become the
 dominant player in the online search market in China,'' said Wang Yan, CEO of
 SINA, ''We have one of the largest online traffic and 'stickiest' online users
 in China.  Combined with those are our vast online and mobile resources.  I am
 confident that the introduction of iAsk will go a long way towards enhancing
 the online community experience of our users and cementing our online media
 leadership in China.''
