Additionally the content may change rapidly and informationthat was previously contributed by a known user may be updated by anunknown user. End users are now faced with more challenges as theyevaluate how much they may want to rely on information that wasgenerated and updated in this manner. A trust management layer hasbecome an important requirement for the continued growth andacceptance of collaboratively developed and maintained informationresources. In this paper, we will describe our initialinvestigations into designing and implementing an extensible trustmanagement layer for collaborative and/or aggregated repositories ofinformation. We leverage our work on the Inference Web explanationinfrastructure and exploit and expand the Proof Markup Language tohandle a simple notion of trust. Our work is designed to supportrepresentation, computation, and visualization of trust information.We have grounded our work in the setting of Wikipedia. In thispaper, we present our vision, expose motivations, relate work todate on trust representation, and present a trust computationalgorithm with experimental results. We also discuss some issuesencountered in our work that we found interesting. inproceedings Proceedings of the WWW'06 Workshop on Models of Trust for the Web (MTW'06) KSL-06-05 Investigations into Trust for Collaborative Information Repositories: A Wikipedia Case Study KSL-06-05 2006 Year Tr id Title Computer science Wiki Trust Tag Inference web Relation Paper url Media:KSL-06-05.pdf Paper May Month Key Booktitle Bibtype Mayukh Bhaowal Dhyanesh Narayanan Li Ding Paulo Pinheiro da Silva Honglei Zeng Deborah L.
