The popularity and proliferation of Wikis have created a new set of challenges for trust research because the content in a Wiki can be contributed by a wide variety of users and can change rapidly. Nevertheless, most Wikis lack explicit trust management to help users decide how much they should trust an article or a fragment of an article. In this paper, we investigate the dynamic nature of revisions as we explore ways of utilizing revision history to develop an article fragment trust model. We use our model to compute trustworthiness of articles and article fragments. We also augment Wikis with a trust view layer with which users can visually identify text fragments of an article and view trust values computed by our model. inproceedings Proceedings of the 2nd International Conference on Collaborative Computing: Networking, Applications and Worksharing (collaboratecom'06) KSL-06-16 1-10 Mining Revision History to Assess Trustworthiness of Article Fragments KSL-06-16 2006 Year Tr id Title Computer science Tag Paper url Pages November Month Key Booktitle Bibtype Deborah L.
