The term "collaboration" was introduced into computer science by the collaborative work community (e.g., CSCW - computer supported cooperative work). Traditionally, collaborative work meant using computers as an explicit medium to facilitate collaborative activity, e.g., writing a document. Collaborative activities have been broadened to include discussions, chat rooms, wikis, but the term "collaboration" maintained its connotation of a closed group of collaborators working over some concrete computer representation of documents or results.
In contrast, social networks were introduced to use computers as an implicit medium for facilitating communications and collaborative activities, but not necessarily over a concrete document. Resources and information can be easily shared and distributed by social networks, enabling phenomena such as flash mob and crowd sourcing. These techniques have been demonstrated in the DARPA Network Challenge (the Red Balloon competition). In contrast to traditional cooperative work on data (e.g., documents), collaboration over social networks typically focus on metadata (e.g., collaborative recommendation) and operate in an open environment (e.g., "like" in Facebook).
Panelists will discuss the impact of social networks on the broadening of the term "collaboration". First, they will comment on some of the differences and similarities, comparing the traditional meaning of collaboration with the new meaning of collaboration. Second, they will discuss the new system requirements for supporting the new kind of collaboration. For example, security and privacy are more easily controlled in a traditional closed environment, but much more challenging in an open social network. Third, they will discuss the new research challenges that arise when social networks are used for collaboration.
