We consider agents who choose by proceeding through an ordered list of criteria and give the lower bound on the number of criteria that are needed for an agent to make decisions that obey a given set of preference rankings. Agents with rational preferences can always use lists with the lower-bound number of criteria while any agent with nonrational preferences must on some domains use strictly ...

The paper discusses the significance of factors in anaphora resolution and on the basis of a comparative study argues that what matters is not only a good set of reliable factors but also the strategy for their application. The objective of the study was to find out how well the same set of factors worked within two different computational strategies. To this end, we tuned two anaphora resoluti...

this study was intended first to categorize the l2 learners in terms of their learning style preferences and second to investigate if their learning preferences are related to lexical inferencing. moreover, strategies used for lexical inferencing and text related issues of text density and parts of speech were studied to determine their moderating effects and the best predictors of lexical infe...

this paper presents a new approach for assessing agricultural landscapes based on mixturemethods and the study and definition of aesthetic attributes as lines, forms, texture, spatial composition, scaleand color as they are the closest to human perceptual aesthetic attributes. a set of variables capable ofquantifying those attributes in a simple, objective and systematized way will be proposed....

Most commercial search engines give the same results for the same query, not considering the user's interest. User profiling is a fundamental component of any personalization application. Most existing user profiling strategies are based on object that users are interested in ( positive preferences), but not the objects that users dislike ( negative preferences). This paper focuses on sear...

We provide a generalization of Harsanyi (1955)’s aggregation theorem to the case of incomplete preferences at the individual and social level. Individuals and society have possibly incomplete expected utility preferences that are represented by sets of expected utility functions. Under Pareto indifference, social preferences are represented through a set of aggregation rules that are utilitaria...

Ghirardato, Maccheroni, and Marinacci (2004) propose a method for distinguishing between perceived ambiguity and the decision-maker’s reaction to it. They study a general class of preferences which they dub invariant biseparable. This class includes CEU and MEU. This note presents some examples which illustrate their results. Keywords, Ambiguity, multiple priors, invariant biseparable preferenc...
