Trust between a pair of users is an important piece of information for users in an online community (such as electronic commerce websites and product review websites) where users may rely on trust information to make decisions. In this paper, we address the problem of predicting whether a user trusts another user. Most prior work infers unknown trust ratings from known trust ratings. The effectiveness of this approach depends on the connectivity of the known web of trust and can be quite poor when the connectivity is very sparse which is often the case in an online community. In this …

A satisfactory and robust trust model is gaining importance in addressing information overload, and helping users collect reliable information in online communities. Current research on trust prediction strongly relies on a web of trust, which is directly collected from users based on previous experience. However, the web of trust is not always available in online communities and even though it is available, it is often too sparse to predict the trust value between two unacquainted people with high accuracy. In this paper, we propose a framework to derive degree of trust based on users' expertise and users' affinity for certain …

An Online Community For Teachers Of Children With Autism To Support, Observe, And Evaluate Communication Enabled With Smartphones, Gianluca De Leo, Gondy Leroy

We are developing an online community for teachers of children diagnosed with autism spectrum disorder that will provide tools to share, analyze, and evaluate assisted communication. The data will be collected from software on smartphones that allows children to communicate with teachers using images. Since this is the first approach towards systematic data collection for children with ASD, we expect a significant impact on current teaching methods.
