The rise of Internet and Web technologies has enabled traditional scientific collaborations to turn outward and connect distributed participants across enterprises and research institutes. By removing the geographical distance barriers, scientists and engineers from different organizations are able to establish collaboration relationships and share information correspondingly. Under many circumstances, the establishment of collaboration relationship is highly dynamic and may vary tremendously in purpose, scope, size, duration, and the number of involved participants. We refer this type of collaboration as ad-hoc collaboration [22, 24]. Ad-hoc collaboration allows individual participants who belong to many different organizations to spontaneously establish or join collaborations, and dynamically perform a variety of activities such as communication, information sharing, cooperation, problem solving, and negotiation [2, 35]. Compared to well-structured collaborations, the formulation of ad-hoc collaboration is essentially more transient. Interactions among collaborating users are not always predictable, and there is no pre-established global consensus of trustworthiness among all participating parties. As a result, it requires a more light-weighted infrastructure without pre-configured environments or central management authorities in ad-hoc collaboration.
