Framework Proposal to Evaluate Trustworthiness in an Online Community

This work presents a proposal to evaluate members' trustworthiness in online communities. Both members’ interactions and the relevance of their contributions to the community are analyzed as trust evidences. To establish the relevance of a contribution, the community’s vocabulary is studied and its occurrence in each member's interaction is evaluated. We propose a framework that supports both the trust model and the creation of the community’s vocabulary. The software architecture extends current collaborative systems and the trust model uses information extracted from the artifacts generated by the online community. An experiment in the InVesalius community, available at Brazilian Public Software Portal, is presented.
