In order to provide information and communication services without disrupting human activity, information services must implicitly conform to the current context of human activity. However, the variability of human environments and human preferences make it impossible to preprogram the appropriate behaviors for a context aware service. One approach to overcoming this obstacle is to have service...

The efficiency of automated multi-issue negotiation depends on the availability and quality of knowledge about an opponent. We present a generic framework based on Bayesian learning to learn an opponent model, i.e. the issue preferences as well as the issue priorities of an opponent. The algorithm proposed is able to effectively learn opponent preferences from bid exchanges by making some assum...

We investigate closed captions and discrete cosine transform coefficients individually as features for classifying movies by genre and learning user preferences. Using a support vector machine as the classifier, we find that these features work very well for classification by genre but the results are less satisfactory when learning user preferences.

This paper focuses to a formal model of user preference learning for content-based recommender systems. First, some fundamental and special requirements to user preference learning are identified and proposed. Three learning tasks are introduced as the exact, the order preserving and the iterative user preference learning tasks. The first two tasks concern the situation where we have the user’s...

To help a person make proper decisions, we must first understand the person’s preferences. A natural way to determine these preferences is to learn them from the person’s choices. In principle, we can use the traditional machine learning techniques: we start with all the pairs (x, y) of options for which we know the person’s choices, and we train, e.g., the neural network to recognize these cho...

the steady growing innovations in the area of information and communication technology have raised new concepts and possibilities in different life aspects. in the field of further education and professional training, electronic learning and web-based education are perhaps the most prominent ones. proponents of this technology claim that e-learning courses are at least as effective as correspon...

This article offers a brief comparative look at American and British jurisprudential pending selection reforms, and argues that American states could improve their appointive systems by incorporating modern personnel recruitment and hiring practices. To restore public confidence in the courts, people must believe that judges exercise legitimate authority, undistorted by personal or partisan pre...
