The founder of Wikipedia is developing a Wiki-based search engine to compete with established commercial search engines from Google and Yahoo.

Jimmy Wales announced plans to develop the search engine in a Dec. 23 online posting.

The Wikimedia Foundation, which manages the Web site Wikipedia.com, a user-edited online encyclopedia, emphasizes that the search engine project is not associated with the foundation.

Wales said that current search engine technology, using complex algorithms to complete searches, is "broken."

"It is broken for the same reason that proprietary software is always broken: lack of freedom, lack of community, lack of accountability (and) lack of transparency. Here, we will change all that," wrote at the site, search.wikia.com.

Wales promotes Wikia as "a new kind of search engine, which relies on human intelligence to do what algorithms cannot." He invited members of the Wiki community to help design the Wikia search engine, which he described as "an open-source alternative for Web search."

He cited open source search projects as Nutch and Lucene as related efforts that can help in the development of Wikia.

Wikipedia is maintained with donations from users. The foundation filed its first financial statement Nov. 21, listing just over $1 million in assets for the year ended June 30.

While Wikipedia began mostly as a resource on technology issues, it has expanded to cover more general topics. And although it's populist mission is to let users edit content, it has had to correct some embarrassing inaccuracies. Most notably, it let stand for four months in 2005 a posting identifying newspaper publisher John Seigenthaler Sr. as involved in the assassinations of President John F. and Sen. Robert F. Kennedy in the 1960s. It removed the posting only after Seigenthaler objected.

Wales and the Wikimedia Foundation did not respond to requests for comment.
