<p>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. </p> <p>We call this a <em>content-driven</em> reputation, since the reputation is computed automatically via text analysis.
