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.

Some interesting questions• What is the meaning of 3 essential urges of human being

(人有三急 )？• Why do one of the lion statues of HSBC has its mouth

Implication to Internet• Access points of information are now diversified and

Search has become even more important.• 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.• Potential threat to some of the traditional industries like

music labels and software companies.• Potential impact to the Government.
