Champaign, John, Zhang, Jie and Cohen, Robin (2011): Coping with Poor Advice from Peers in Peer-Based Intelligent Tutoring: The Case of Avoiding Bad Annotations of Learning Objects. In: Proceedings of the 2011 Conference on User Modeling, Adaptation and Personalization 2011. pp. 38-49.

In this paper, we examine a challenge that arises in the application of peer-based tutoring: coping with inappropriate advice from peers. We examine an environment where students are presented with those learning objects predicted to improve their learning (on the basis of the success of previous, like-minded students) but where peers can additionally inject annotations. To avoid presenting annotations that would detract from student learning (e.g. those found confusing by other students) we integrate trust modeling, to detect over time the reputation of the annotation (as voted by previous students) and the reputability of the annotator. We empirically demonstrate, through simulation, that even when the environment is populated with a large number of poor annotations, our algorithm for directing the learning of the students is effective, confirming the value of our proposed approach for student modeling. In addition, the research introduces a valuable integration of trust modeling into educational applications.

Zhang, Jie, Zheng, Changwen, Lv, Pin and Hu, Xiaohui (2010): Implicit restricted quadtree based visualization of large scale terrain. In: Proceedings of the 2010 ACM Symposium on Virtual Reality Software and Technology 2010. pp. 177-178.

Realistic rendering of large scale terrain scene in real-time is an important subject in virtual reality (VR) to construct a virtual environment with immersion and interactivity [Zhao 2009]. Large scale terrain scene visualization is popular in a variety of fields such as geographic information systems (GIS), military maneuvers, games, flight training and so on. Many visualization algorithms for terrain scenes have been proposed during the past decades, but to the authors' knowledge, approaches with high visual accuracy as well as low memory and time complexity have not been developed yet.

Seth, Aaditeshwar, Zhang, Jie and Cohen, Robin (2010): Bayesian Credibility Modeling for Personalized Recommendation in Participatory Media. In: Proceedings of the 2010 Conference on User Modeling, Adaptation and Personalization 2010. pp. 279-290.

In this paper, we focus on the challenge that users face in processing messages on the web posted in participatory media settings, such as blogs. It is desirable to recommend to users a restricted set of messages that may be most valuable to them. Credibility of a message is an important criteria to judge its value. In our approach, theories developed in sociology, political science and information science are used to design a model for evaluating the credibility of messages that is user-specific and that is sensitive to the social network in which the user resides. To recommend new messages to users, we employ Bayesian learning, built on past user behaviour, integrating new concepts of context and completeness of messages inspired from the strength of weak ties hypothesis, from social network theory. We are able to demonstrate that our method is effective in providing the most credible messages to users and significantly enhances the performance of collaborative filtering recommendation, through a user study on the dataset.
