About Knowledge Search
• Users can ask questions they want. Other users will help to answer the questions.
• The best answer is chosen either by the question asker or by public polling.
• Once a question is paired with the best answer, a knowledge is formed.
• Knowledge can be retrieved through searching.• A good complement to purely crawl base search because of human
information organization• Extend coverage to content that might not “exist” on the web• Good knowledge is encouraged.• First available in Korea, then Japan, Taiwan, the Mainland of China,
Hong Kong and then Western countries.

• Information is no longer managed by a small group of people; instead now by a group of community.
• Good quality content might come from Users Generated Content (UGC) but with no guarantee of content.
