Two types of actions, i.e., information provisioning and information evaluation, are common in such communities and are valuable in scoring each contribution. The EigenRumor algorithm, proposed here, calculates the contribution scores based on a link analysis approach by considering these actions as links from participants to information objects. The algorithm has similarities to Kleinberg{\~A}�{\^A}�{\^A}�s HITS algorithm in that both algorithms are based on the mutually reinforcing relationship of hubs and authorities but the EigenRumor model is not structured from page-to-page links but from participant-to-object links and is extended by the introduction of several new factors. The scores calculated by this algorithm can be used to identify {\~A}�{\^A}�{\^A}�good{\~A}�{\^A}�{\^A}� information and participants who contribute much to a community, which allows for the provisioning of incentives to such participants to promote their continuous contribution to the community.

Traditional measures of topical relevance, timeliness, specificity and credibility are inadequate when it comes to blogs, however, due to their short length, high degree of quotation, exophoricity, and the short life cycle of blog postings. In this paper, we motivate a novel metric for blog credibility that is one of the metrics underlying a blog search and analytics engine we are constructing.Mon Nov 05 17:28:31 CET 2007New York, NY, USAAIRWeb '07: Proceedings of the 3rd international workshop on Adversarial information retrieval on the web73--80Computing trusted authority scores in peer-to-peer web search networks2007search authority Mon Nov 05 17:28:31 CET 2007New York, NY, USAWWW '07: Proceedings of the 16th international conference on World Wide Web221--230Expertise networks in online communities: structure and algorithms2007communities expertise authority Mon Nov 05 17:28:31 CET 2007New York, NY, USAWWW '07: Proceedings of the 16th international conference on World Wide Web261-270A ContentDriven Reputation System for the Wikipedia2007reputation authority wikipedia
