Tagging (or bookmarking) online resources with representative keywords is one of the most popular and practical approaches for giving identity to the objects. Human taggers in social tagging systems give identity to the objects. Tagged objects also represent the perception or identity of their human taggers in return. Although users' interest and their perception about Web content might change over time, most current approaches define a fixed identity for the objects.These approaches always recommend objects to the users based on their fixed, defined identities since they use a source of knowledge that does not evolve. In our social semantic tagging system, COD (Collaborative Ontology Development), we update identities of the users and Web contents dynamically based on the latest collective opinion of the evolving communities of relevant users [1]. In this poster, we present how entrepreneurs can define a reliable representation of their commonsense knowledge about different entrepreneurial entities by using COD. CODer Entrepreneurs in the automatically formed communities can dynamically improve identity of the entrepreneurial objects related to their expertise or interests.
