Proceedings of the 20th International Conference Companion on World Wide Web, WWW 2011 English 2011 We report in this short paper results on inferring a signed network (a "web of trust") from user interactions. On the Wikipedia network of contributors, from a collection of articles in the politics domain and their revision history, we investigate mechanisms by which relationships between contributors - in the form of signed directed links - can be inferred from their interactions. Our preliminary study provides valuable insight into principles underlying a signed network of Wikipedia contributors that is captured by social interaction. We look into whether this network (called hereafter WikiSigned) represents indeed a plausible configuration of link signs. We assess connections to social theories such as structural balance and status, which have already been considered in online communities. We also evaluate on this network the accuracy of a learned predictor for edge signs. Equipped with learning techniques that have been applied before on three explicit signed networks, we obtain good accuracy over the WikiSigned edges. Moreover, by cross training-testing we obtain strong evidence that our network does reveal an implicit signed configuration and that it has similar characteristics to the explicit ones, even though it is inferred from interactions. We also report on an application of the resulting signed network that impacts Wikipedia readers, namely the classification of Wikipedia articles by importance and quality. 0 0
