Our hope is to integrate ideas from diverse domains such as (but not limited to) HCI, cognitive science, AI, psychology, computer science, information science, and computational linguistics to generate novel perspectives on understanding, characterizing, and predicting system characteristics and user behavior at both the individual and aggregate/social levels. We also hope that his workshop will provide a venue for researchers in both academia and industry to discuss the use of cognitive models to inform designs of future social information systems in diverse application areas.</p></div></span></div><div><br></div><div style="text-align: justify; "><font class="Apple-style-span" face="'Courier New'"><font class="Apple-style-span" size="3"><span class="Apple-style-span" style="font-size: 13px; ">We broadly define social information systems as systems that support social functions. Difference forms of social information systems have gained significant popularity over the last decade. For example, social networking sites such as Facebook and MySpace and social tagging systems such as del.icio.us and CiteUlike.org attract several thousand users a day. While serving different social functions, these systems provide its users increased social presence and opportunities for easy collaboration and social interaction. User behavior on these systems has been generally conducted based on analysis of snapshots of long-term user interaction patterns such as logs of user activities, connections between users, etc. But, very little is known about the cognitive mechanisms underlying these interactions. A good understanding of the individual cognitive mechanisms is important for engineering better interface representations and interaction methods that support user behavior in social systems. Additionally, models that aim at characterizing these mechanisms can complement existing research and provide a basis for a more complete explanation of emergent social and collaborative behavior in social information systems.</span></font></font></div><div style="text-align: justify; "><font class="Apple-style-span" face="'Courier New'" size="3"><span class="Apple-style-span" style="font-size: 13px; "><br></span></font></div><div style="text-align: justify; "><font class="Apple-style-span" face="'Courier New'" size="3"><span class="Apple-style-span" style="font-size: 13px; "><div class="post"><h3><a name="Attend"><u>Submission</u></a></h3><div class="entry"><p>We welcome submission from researchers and practitioners who are interested in developing computational models of social information systems.
