The task of parameter/function estimation has been at the center of scientific attention for a long time and it comes under different names such as filtering, prediction, beamforming, classification, regression. Conventionally, the task has been treated as an optimization task of an appropriately...

Intelligent virtual environments are a relatively new scientific field that is concerned with the representation of worlds by means of computers with a focus on intelligent virtual agent behaviour. The design and development of intelligent virtual environment systems requires the convergence of a...

Allen's hourglass is motivated by the need to handle robustly the uncertainty of temporal intervals, e.g. as it occurs in automated event detection in video streams. We introduce a two-dimensional mapping of Allen's relations, based on orthogonal characteristics of interval relations, namely...

The presentation describes a set of practices and methods that were developed within the OKKAM project (www.okkam.org), related to the identification of entities and the managment of related information in view of the Semantic Web. We will also refer to a machine learning and user modeling problem...

This talk is going to discuss the issues of data and knowledge integration. The first part of the talk is going to concentrate on data integration, i.e. combining the data of different data sources by creating a unified representation of these data. Two core problems in data integration are schema...

Web personalization and Web directories have been proposed as potential solutions to the problem of information overload on the WWW. The essence of personalization is the adaptability of information systems to the needs of their users, whilst Web directories are an attempt to thematically organize...

Paraphrasing methods recognize, generate, or extract phrases, sentences, or longer natural language expressions that convey almost the same information. Textual entailment methods, on the other hand, recognize, generate, or extract pairs of natural language expressions, such that a human who reads...
