Competition Produces Vandalism Detection For Wikis

[sl4shd0t]

marpot writes "Recently, the 1st International Competition on Wikipedia Vandalism Detection (PDF) finished: 9 groups (5 from the USA, 1 affiliated with Google) tried their best in detecting all vandalism cases from a large-scale evaluation corpus. The winning approach (PDF) detects 20% of all vandalism cases without misclassifying regular edits; moreover, it can be adjusted to detect 95% of the vandalism edits while misclassifying only 30% of all regular edits. Thus, by applying both settings, manual double-checking would only be required on 34% of all edits. Nothing is known, yet, whether the rule-based bots on Wikipedia can compete with this machine learning-based strategy. Anyway, there is still a lot potential for improvements since the top 2 detectors use entirely different detection paradigms: the first analyzes an edit's content, whereas the second (PDF) analyzes an edit's context using WikiTrust."http://a.fsdn.com/sd/facebook_icon_large.png (http://www.facebook.com/sharer.php?u=http%3A%2F%2Fdevelopers.slashdot.org% 2Fstory%2F10%2F09%2F26%2F1443206%2FCompetition-Produces-Vandalism-Detection-For-Wikis) http://a.fsdn.com/sd/twitter_icon_large.png (http://twitter.com/home?status=+Competition+Produces+Vandalism++Detec tion+For+Wikis%3A+http%3A%2F%2Fbit.ly%2Fdg5ald)
