Google Korea, the local unit of Android giant Google Inc., on Tuesday unveiled a new search model aimed at providing more comprehensive search results for South Korean users as it competes with homegrown Web portals that dominate the market.
The Korean version of "Knowledge Graph," which was launched in a global version last year, enables users to find more accurate search results by showing various texts, images and information linked to a certain keyword, Google Korea officials said in a media session in downtown Seoul.
The new service provides the search results on resources of roughly 18 billion links related to around 570 million key words, according to the company. The service is available in both PC and mobile versions.
Google Korea said it plans to expand the range of localized content and projected the number of categories, such as movies, actors, politicians and musicians, to grow two to three fold each year.
The new service launch comes as Google is racing to bolster its local market share amid the dominance of homegrown Web portals such as Naver.com and Daum.net.
As of Tuesday, Naver.com, operated by South Korean firm NHN Corp., ranked as the most-visited Web site, followed by Daum.net, operated by Daum Communications Corp., according to market researcher Rankey.com. Google ranked seventh.
The South Korean portals have already been providing extensive links and displays of keywords, actor filmographies and baseball league game results.
"Knowledge Graph and portal services may look similar, but their objectiveness and neutrality is different. (Knowledge Graph) collects data from various sources without artificial intervention," said Ted Cho, the engineering site director at Google Korea.
