Dealing with user preferences is becoming a widespread issue in novel data-intensive application domains, such as electronic catalogs, e-commerce, multimedia databases, and real estates. Given a set of preferences, an important problem is to efficiently determine which are the “best” objects, according to such preferences. In this paper we assume that preferences are expressed in a qualitative ...

Available resources can often be limited with regard to the number of demands. In this paper we propose an approach for solving this problem using the mechanisms of multi-item auctions for allocating the resources to a set of software agents. We consider the resource allocation problem as a market with vendor and buyer agents participating in a multi-item auction. The agents exhibit different a...

We present a method for detecting action items in spontaneous meeting speech. Using a supervised approach incorporating prosodic, lexical and structural features, we can classify such items with a high degree of accuracy. We also examine how well various feature subclasses can perform this task on their own.

Different proposals have been made in recent years to exploit Social Web tagging data to improve recommender systems. The tagging data was used for example to identify similar users or viewed as additional information about the recommendable items. In this work we propose to use tags as a means to express which features of an item users particularly like or dislike. Users would therefore not on...

The biology and genetics of developmentally regulated resistance to rusts and powdery mildews is being examined through a study of wheat mutants that express enhanced resistance to one or more of these pathogens. Mutants, isolated from the wheat varieties Hobbit ‘sib’ and Guardian, are being mapped to determine the number, location, and effect of each mutation contributing to each pathogen resi...

Introduction Compared to parents of adults with other types of disabilities, parents of adults with autism spectrum disorder (ASD) experience worse well-being. Thus, it is crucial to identify the individual, parent and social–environmental correlates of caregiving experiences among parents of adults with ASD. Method For this study, 130 parents of adults with ASD responded to a survey about care...

Monitoring frequently occuring items is a recurring task in a variety of applications. Although a number of solutions have been proposed there has been few to address the problem in a distributed networked environment. Most past solutions relied upon approximating results to lower communication overhead. In this paper we introduce a new algorithm designed for continuously tracking frequent item...

In this paper, we study the problem of assigning indivisible items under the following constraints: 1) each item belongs to one of the p categories, 2) each agent is required to get exactly one item from each category, 3) no free disposal, and 4) no monetary transfer. We first characterize serial dictatorships by a minimal set of 3 properties: strategy-proofness, non-bossiness, and categorywise...
