document: iLink : search and routing in social networks The growth of Web 2.0 and fundamental theoretical breakthroughs have led to an avalanche of interest in social networks . This paper focuses on the problem of modeling how social networks accomplish tasks through peer production style collaboration . We propose a general interaction model for the underlying social networks and then a specific model ( iLink for social search and message routing . A key contribution here is the development of a general learning framework for making such online peer production systems work at scale . The iLink model has been used to develop a system for FAQ generation in a social network ( FAQtory ) , and experience with its application in the context of a full-scale learning-driven workflow application ( CALO ) is reported . We also discuss methods of adapting iLink technology for use in military knowledge sharing portals and other message routing systems . Finally , the paper shows the connection of iLink to SQM , a theoretical model for social search that is a generalization of Markov Decision Processes and the popular Pagerank model .
