Google develops 'web 2.0' encyclopaedia

Search and advertising giant Google is developing a user-generated online encyclopaedia that could rival Wikipedia.

Google has named the scheme the "knol project" - a knol being a "unit of knowledge" - according to a blog post by Google engineering vice president Udi Manber. The company aims to tie strong identities to contributing authors and those seeking to edit knols.

Manber wrote "Our goal is to encourage people who know a particular subject to write an authoritative article about it. The goal is for knols to cover all topics, from scientific concepts, to medical information, from geographical and historical, to entertainment, from product information, to how-to-fix-it instructions."

Google will host and provide tools to produce and edit knol web pages but will not edit or advocate any of the content. However, entries Google judges to be of higher quality will be given a higher page ranking in Google search.

Entries will be rated by the community and will be able to be reviewed after the unspecified testing period. The project is currently in beta and has been sent to a small group of testers. Once the knol tool goes live, contributors will be able to monetise their pages by including Google ads.
