Abstract

In this research work, we introduce the concept of a reputation service to evaluate user collaboration towards community or system goal. Online reputation mechanisms allow members of a community to submit their opinions (feedback) regarding other community members and their publication activity. Submitted opinions are analyzed, aggregated with feedback posted by other members and made publicly available to the community in the form of member feedback profiles. We propose a conceptual system that can be used in several contexts, namely in our public transportation recommender system developed in the framework of the European Project START.
