摘要
We present a content-driven reputation system for Wikipedia authors: authors gain reputation when their contributions are long-lived, and they lose reputation when their contributions are undone in short order. We have evaluated such a reputation system on the Italian and French Wikipedias: our data shows that author reputation is a good predictor for the quality of future edits by the author. The reputation could be used to flag out recent text from low-reputation authors, thus providing an automated notion of text trust. The reputation could also be used to grant edit access to controversial pages.
