Preference-based item recommendation is an important technique employed by online product catalogs for recommending items to buyers. Whereas the basic mathematical mechanisms used for computing value functions from stated preferences are relatively simple, developers of online catalogs need flexible formalisms that support the description of a wide range of value functions and map to scalable i...

Factors governing human preference for artwork have long been studied but there remain many holes in our understanding. Bearing in mind contextual factors (both the conditions under which the art is viewed, and the state of knowledge viewers have regarding art) that play some role in preference, we assess in this paper three questions. First, what is the relationship between perceived similarit...

The study at hand explores the influence of value-added services offered in addition to a motor insurance product on the customer's preference structure. It addresses the need of insurance companies to extend their core business with different types of supplementary services. A choice-based conjoint analysis is conducted which considers the price for the insurance product, the insurance franchi...

In this paper we present a new interactive procedure for multiObjective optimization, which is based on the use of a set of value functions as a preference model built by an ordinal regression method. The procedure is composed of two alternating stages. In the first stage, a representative sample of solutions from the Pareto optimal set (or from its approximation) is generated. In the second st...

In this paper, we first use a fuzzy preference relation with a membership function representing preference degree forcomparing two interval-valued fuzzy numbers and then utilize a relative preference relation improved from the fuzzypreference relation to rank a set of interval-valued fuzzy numbers. Since the fuzzy preference relation is a total orderingrelation that satisfies reciprocal and tra...

The relative reinforcing value of toys was assessed in the absence of, and immediately following, participant observation of a peer manipulating one of the toys. Preference assessments were used to identify preference hierarchies. Reinforcer assessments were conducted with a high-preference item, a low-preference item, and a control. Each participant allocated responding toward the high-prefere...

In a decision making context, multiple choices of actions are usually ooered to solve a particular problem. Consequently, the question of preferences among the actions will occur. The ordering of recommended actions by preference is made by taking into account the states of the universe of discourse. We develop here a logic L p for reasoning about preferences in such circumstances. The language...

While decision theory provides an appealing normative framework for representing rich preference structures, eliciting utility or value functions typically incurs a large cost. For many applications involving interactive systems this overhead precludes the use of formal decision-theoretic models of preference. Instead of performing elicitation in a vacuum, it would be useful if we could augment...

Inspired by the concept of deviation measure between two linguistic preference relations, this paper further defines the deviation measure of a linguistic preference relation to the set of consistent linguistic preference relations. Based on this, we present a consistency index of linguistic preference relations and develop a consistency measure method for linguistic preference relations. This ...
