Analysis of 〈X,R〉 models is considered as part of a general approach to solving optimization problems with fuzzy coefficients. This approach involves a modification of traditional optimization methods and is associated with formulating and solving one and the same problem within the framework of mutually interrelated models by constructing equivalent analogs with fuzzy coefficients in objective...

Several important problems in ecology, evolution and conservation biology are affected by habitat selection in dispersing animals. Experience in the natal habitat has long been considered a potential source of variation in the habitat preferences displayed when dispersers select a post-dispersal habitat. However, the taxonomic breadth of this phenomenon is underappreciated, in part because part...

Preference elicitation is concerned with inferring a latent utility function from user feedback. Typical elicitation approaches iteratively query the user about (supposedly informative) pairs of candidate configurations; the collected pairwise preference constraints are used to improve the utility estimate. The ongoing transition from flat to structured configuration spaces is opening promising...

In this paper, the multi-person decision making problems with various different types of incomplete linguistic preference relations are studied. Some new concepts, including incomplete uncertain linguistic preference relation, incomplete triangular fuzzy linguistic preference relation, incomplete trapezoid fuzzy linguistic preference relation, expected incomplete linguistic preference relation ...

PrefWork is a framework for testing of methods of induction of user preferences. PrefWork is thoroughly described in this paper. A reader willing to use PrefWork finds here all necessary information sample code, configuration files and results of the testing are presented in the paper. Related approaches for data mining testing are compared to our approach. There is no software available specia...

Destination recommendation systems not only recommend but also persuade. The goal of this study was to investigate the potential influences of the relevance, transparency of and effort required by the preference elicitation process on the perceived fit of a destination recommendation, while simultaneously considering user perceptions of the elicitation process (perceived enjoyment and personali...

While stable matching problems are widely studied, little work has investigated schemes for effectively eliciting agent preferences using either preference (e.g., comparison) queries or interviews (to form such comparisons); and no work has addressed how to combine both. We develop a new model for representing and assessing agent preferences that accommodates both forms of information and (heur...

Over the past decade a significant amount of recommender systems research has demonstrated the benefits of conversational architectures that employ critique-based interfacing (e.g., Show me more like item A, but cheaper). The critiquing phenomenon has attracted great interest in line with the growing need for more sophisticated decision/recommendation support systems to assist online users who ...

Introduction Current proposals for preference-based information access [4] seem to ignore that users should be acquainted with the information space and the available choices for describing effectively their preferences. Furthermore, users rarely formulate complex (preference or plain) queries, because it is a laborious and difficult task for them. We will demonstrate a system for interactive e...
