The current trend <o:p></o:p></p><p class=MsoNormal>towards software apps using the cloud to store and process information that can <o:p></o:p></p><p class=MsoNormal>be downloaded on social networks and mobile devices platforms brings new importance <o:p></o:p></p><p class=MsoNormal>to the area of decentralized user modeling. Frameworks for dynamic and purpose <o:p></o:p></p><p class=MsoNormal>based sharing of user mode fragments among apps needs to take into account the <o:p></o:p></p><p class=MsoNormal>trust among these apps. The trust of one agent in another can be viewed as a simple <o:p></o:p></p><p class=MsoNormal>user/agent model. Researchers in the area of trust and reputation mechanisms have <o:p></o:p></p><p class=MsoNormal>studied for many years techniques allowing autonomous agents and peers to share, <o:p></o:p></p><p class=MsoNormal>aggregate and make decisions based on these simple user models. User modeling <o:p></o:p></p><p class=MsoNormal>researchers can gain useful insights from this area. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Second, the area of trust and reputation modeling has experienced rapid growth <o:p></o:p></p><p class=MsoNormal>in the past 7 years. Recently, two important trends have been emerging in this area. <o:p></o:p></p><p class=MsoNormal>One is the computational modeling of agents' cognition, such as subjectivity and <o:p></o:p></p><p class=MsoNormal>disposition, to achieve more accurate trust and reputation modeling. Another trend is <o:p></o:p></p><p class=MsoNormal>modeling of agents' trust using a stereotype approach to deal with the problem of <o:p></o:p></p><p class=MsoNormal>lack of experience. Both of these trends are closely related to studies in user modeling. <o:p></o:p></p><p class=MsoNormal>The evidential success of these new trends inspires and encourages researchers in the <o:p></o:p></p><p class=MsoNormal>trust community to make use of the rich literature in user modeling to develop more <o:p></o:p></p><p class=MsoNormal>comprehensive trust and reputation modeling approaches.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>A third important way in which research in user modeling overlaps with trust is the <o:p></o:p></p><p class=MsoNormal>user’s trust in the adaptive / personalized application. In effect it is a symmetrical <o:p></o:p></p><p class=MsoNormal>area to that of user modeling: while user modeling suggests that the system models the <o:p></o:p></p><p class=MsoNormal>user, here the user models the system. It relates to issues of user's understanding of <o:p></o:p></p><p class=MsoNormal>the application, and of the privacy and integrity of the user model data, both of which <o:p></o:p></p><p class=MsoNormal>are actively studied in the user modeling community. Facilitating the user's understanding <o:p></o:p></p><p class=MsoNormal>and trust in the system's functioning and the way it manages the user's data is very <o:p></o:p></p><p class=MsoNormal>important, since it determines the user's acceptance of the application's recommendations <o:p></o:p></p><p class=MsoNormal>or persuasion, the user's satisfaction with the application's functionality, and <o:p></o:p></p><p class=MsoNormal>ultimately, its success. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The previous TRUM workshops have focused on users trust in systems. We now look <o:p></o:p></p><p class=MsoNormal>at trust in a more holistic way: (a) trust between members of the network, (b) <o:p></o:p></p><p class=MsoNormal>trust between a member and the provided online service, and (c) the trust between a member <o:p></o:p></p><p class=MsoNormal>and the service provider. This focus brings yet another intersection between trust research <o:p></o:p></p><p class=MsoNormal>and user modeling, with respect to recommendation systems. Whereas recommendation systems <o:p></o:p></p><p class=MsoNormal>typically rely on users' profiles or preferences, new types of recommendation algorithms <o:p></o:p></p><p class=MsoNormal>are being designed based on trust behavior, thus further enhancing personalization. Finally, we seek to look<o:p></o:p></p><p class=MsoNormal>at trust in a variety of domains and environment (e.g., not exclusively in e-commerce networks).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Topics to be covered in this Workshop include but are not limited to:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Trust and Reputation Modeling<o:p></o:p></p><p class=MsoNormal>- Subjectivity and Disposition in Trust and Reputation Modeling<o:p></o:p></p><p class=MsoNormal>- Cognitive and Computational Trust<o:p></o:p></p><p class=MsoNormal>- Stereotype-based Trust Modeling<o:p></o:p></p><p class=MsoNormal>- Trust in Social Networks<o:p></o:p></p><p class=MsoNormal>- Trust-based Recommender Systems<o:p></o:p></p><p class=MsoNormal>- Trust and Reputation Modeling in Mobile Networks<o:p></o:p></p><p class=MsoNormal>- Trust in Organizations, Institutions and Systems<o:p></o:p></p><p class=MsoNormal>- Models and mechanisms for privacy<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>User Modeling<o:p></o:p></p><p class=MsoNormal>- Decentralized User Modeling approaches<o:p></o:p></p><p class=MsoNormal>- Purpose-based user modeling<o:p></o:p></p><p class=MsoNormal>- Sharing of User model fragments<o:p></o:p></p><p class=MsoNormal>- User modeling in mobile computing, e.g. smart phone apps, vehicles, cameras<o:p></o:p></p><p class=MsoNormal>- User Modeling in ambient and ubiquitous computing<o:p></o:p></p><p class=MsoNormal>- User modeling in Social Networks<o:p></o:p></p><p class=MsoNormal>- Modeling evolving trust relationships among users in social networks<o:p></o:p></p><p class=MsoNormal>- Modeling evolving trust or distrust of users in applications (privacy, integrity of user data)<o:p></o:p></p><p class=MsoNormal>- Modeling trust of users in recommenders and persuasive applications. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>-------------------------------------------------------------------------<o:p></o:p></p><p class=MsoNormal>Committee:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Co-Chairs<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Surya Nepal, CSIRO Computational Informatics, Australia<o:p></o:p></p><p class=MsoNormal>Cecile Paris, CSIRO Computational Informatics, Australia<o:p></o:p></p><p class=MsoNormal>Julita Vassileva, University of Saskatchewan, Canada<o:p></o:p></p><p class=MsoNormal>Jie Zhang, Nanyang Technological University, Singapore<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>PCs<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Julian Jang, CSIRO Computational Informatics, Australia<o:p></o:p></p><p class=MsoNormal>Xin Liu, EPFL, Switzerland<o:p></o:p></p><p class=MsoNormal>Zeinab Noorian, University of Saskatchewan, Canad<o:p></o:p></p><p class=MsoNormal>Guibing Guo, Nanyang Technological University, Singapore<o:p></o:p></p><p class=MsoNormal>Robin Cohen, University of Waterloo, Canada<o:p></o:p></p><p class=MsoNormal>Wanita Sherchan, IBM Research, Australia<o:p></o:p></p><p class=MsoNormal>Thomas Tran, University of Ottawa, Canada<o:p></o:p></p><p class=MsoNormal>Neil Yorke-Smith, American University of Beirut, Lebanon<o:p></o:p></p><p class=MsoNormal>Tim Muller, Nanyang Technological University, Singapore<o:p></o:p></p><p class=MsoNormal>Sanat Kumar Bista, CSIRO Computational Informatics, Australia<o:p></o:p></p><p class=MsoNormal>Carol Fung, Virginia Commonwealth University, US<o:p></o:p></p><p class=MsoNormal>Ebrahim Bagheri, Ryerson University, Canada <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal>--------------------------------------------------------------------------<o:p></o:p></p><p class=MsoNormal>Submission Guidelines:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>All submissions should be in LNCS format, no longer than 12 pages for full papers, <o:p></o:p></p><p class=MsoNormal>6 pages for short papers, and 3 pages for poster papers.
