UCC search arrives...manipulation and pollution to follow soon

Jimmy Wales announced the release of the public "alpha" of his new, for-profit search service, Wikia Search. The service is built on a standard search engine, but its primary feature is that users can evaluate and comment on search results, building a user-contributed content database that Wikia hopes will improve search quality, making Wikia a viable but open (and hopefully profitable) alternative to Google.

Miguel Helft, writer for the New York Times was quick to note that such a search service might be quite vulnerable to manipulation:

Like other search engines and sites that rely on the so-called “wisdom of crowds,? the Wikia search engine is likely to be susceptible to people who try to game the system, by, for example, seeking to advance the ranking of their own site. Mr. Wales said Wikia would attempt to “block them, ban them, delete their stuff,? just as other wiki projects do.

The tension is interesting: Wikia promotes itself as a valuable alternative to Google largely because its search and ranking algorithms are open, so that users know more about why some sites are being selected or ranked more highly than others.

“I think it is unhealthy for the citizens of the world that so much of our information is controlled by such a small number of players, behind closed doors,? [Wales] said. “We really have no ability to understand and influence that process.?

But, although the search and ranking algorithms may be public, whether or not searches are being manipulated by user contributed content will not be so obvious. It is far from obvious which approach is more dependable and "open". Wikia's success apparently will depend on its ad hoc and technical methods for "blocking, banning and deleting" manipulation.
