Ontological framework for trust & reputation for DBE

Todaypsilas e-businesses rely heavily on trust and reputation systems. These systems are key indicators for businesses performance. Businesses that interact with each other for their business needs form a digital business ecosystem (DBE). Members of DBE need to know the trust and reputation value of each other before the start of business interactions. The feedback mechanism is needed so that members of DBE form a unanimous opinion about trustworthiness of any specific member of the community and based their business interactions on this opinion. We present an ontological framework that will combine the feedback from all different trust and reputation information publicly available for a specific member of a domain and gives the knowledge representation on the bases of combined feedback. We call this ontological framework dasiafeedback ontologypsila.
