Content-Driven Reputation

From P2P Foundation

This metric has been tested on the Wikipedia articles, to determine the level of trust one can have in its authors:

"We compute the reputation of Wikipedia authors according to how long their contributions last in the Wikipedia. Specifically, authors whose contributions are preserved, or built-upon, gain reputation; authors whose contributions are undone lose reputation.

We call this a content-driven reputation, since the reputation is computed automatically via text analysis. This contrasts with other reputation systems, such as those in use at [WWW] Ebay, where buyer and seller reputations are computed on the basis of user-provided ratings." (
