English 2012 With over 23 million articles in 285 languages, Wikipedia is the largest free knowledge base on the web. Due to its open nature, everybody is allowed to access and edit the contents of this huge encyclopedia. As a downside of this open access policy, quality assessment of the content becomes a critical issue and is hardly manageable without computational assistance. In this paper, we present FlawFinder, a modular system for automatically predicting quality flaws in unseen Wikipedia articles. It competed in the inaugural edition of the Quality Flaw Prediction Task at the PAN Challenge 2012 and achieved the best precision of all systems and the second place in terms of recall and F1-score. 0 1

English 2012 In this article we describe a new approach to assess Quality Flaw Prediction in Wikipedia. The partially supervised method studied, called PU Learning, has been successfully applied in classifications tasks with traditional corpora like Reuters-21578 or 20-Newsgroups. To the best of our knowledge, this is the first time that it is applied in this domain. Throughout this paper, we describe how the original PU Learning approach was evaluated for assessing quality flaws and the modifications introduced to get a quality flaws predictor which obtained the best F1 scores in the task “Quality Flaw Prediction in Wikipedia” of the PAN challenge. 0 1
