GOOGLE is building its own version of communally-constructed online encyclopedia Wikipedia, which consistently ranks among the most visited websites in the world.
The internet search powerhouse is inviting chosen people to test a free service dubbed "knol", to indicate a unit of knowledge, vice-president of engineering Udi Manber said in a posting on Google's website on Friday.
"Our goal is to encourage people who know a particular subject to write an authoritative article about it," Manber wrote. "There are millions of people who possess useful knowledge that they would love to share, and there are billions of people who can benefit from it.'"
While Wikipedia lets visitors make changes to its online pages, trusting that people with accurate information will correct errors and misleading entries, Google is inviting people to author their own articles.
Pictures of authors will be displayed on their knol web pages, according to a sample provided by Google.
