While recommender systems are in widespread use, they still experience problems. Many recommender systems produce recommendations which the customers find unsatisfactory. Further, these systems often suffer from problems when there are not enough participants, or when new products enter the system. We perceive an opportunity for knowledge-based recommender systems to gain leverage on recommenda...

The paper contains an overview of the roles played by rules and rule-based systems in distributed and multi-agent systems. These roles include an overview of traditional and newly emerging application areas as well as internal agent architectures and frameworks implementing these architectures.

Knowledge-based recommender systems comprise one category of user-modeling system that can draw inferences from user models. This brief paper contains a global description of a multi-faceted, educational, knowledge-based recommender system, including a basic set of descriptors that the model contains, a taxonomy of inferences that might be made over such models, and a listing of literature that...

Today, online reviews for products and services have become an important class of user-generated content and they play a valuable role for countless online businesses by helping to convert casual browsers into informed and satisfied buyers. In many respects, the content of user reviews is every bit as important as the catalog content that describes a given product or service. As users gravitate...

Recommender systems apply statistical and knowledge discovery techniques to the problem of making recommendations during live user interaction. This paper describes a novel approach of building recommender systems for the Web with the aid of usergenerated content. Recently certain communities of Internet users have engaged in creating high quality peer reviewed content for the Web. In our appro...

Traditional intranets have a central location on the network which easily allows the enforcement of a central security policy. They rely on the notion that there is one central entry point for all internal machines. Additionally, all machines that are considered logically inside the intranet reside behind the entry point. Increasingly this is not the case. We propose Smokey, a system that manag...

We introduce Reality-based User Interface System (RUIS), a platform that even novice programmers can easily use for prototyping novel user interfaces. We implemented a puzzle application with a 3D user interface employing modified Nintendo Wii Remotes as 6-DOF controllers to showcase some of the features that are possible with our platform: two-handed gestural interaction, natural interaction m...
