The topic of preference modeling has recently attracted the interest of a number of sub-disciplines in artificial intelligence such as the nonmonotonic reasoning and action and change communities. The approach in these communities focuses on qualitative preferences and preference models which provide more natural representations from a commonsense perspective. In this paper, we show how general...

The increasing variety of mobile multimedia services raises the need for mechanisms to select those services whose capabilities best match individual user requirements. In this paper we present an advanced concept for service personalization in next-generation IP-based mobile systems based on the notion of user preferences. The described concept features several enhancements for personalization...

It is always attractive and challenging to explore the intricate behavior data and uncover people’s motivations, preference and habits, which can greatly benefit many tasks including link prediction, item recommendation, etc. Traditional work usually studies people’s behaviors without time information in a static or discrete manner, assuming the underlying factors stay invariant in a long perio...

As Web services become more and more popular, how to manage multimedia Web services that can be composed as value-added service solutions remains challenging. This paper presents a service-oriented multimedia componentization model to support Quality of Service (QoS)centered, device-independent multimedia Web services, which seamlessly incorporates cuttingedge technologies relating to Web servi...

The research literature on preference modeling, reasoning and eliciting is extensive. Different specification approaches have been proposed to model user preferences such as graphs, logical formalisms and SQL-like constructors. The approach of CP-Nets [2] uses a very simple graphical model which captures users qualitative conditional preference over tuples, under a ceteris paribus semantics. Th...

The design and implementation of advanced personalized database applications requires a preference-driven approach. Representing preferences as strict partial orders is a good choice in most practical cases. Therefore the efficient integration of preference querying into standard database technology is an important issue. We present a novel approach to relational preference query optimization b...
