In the EU funded IDAS project (LE4-8315), demonstrators providing an automated interactive telephone-based directory assistance service have been developed by ten partners from Germany, Greece, Spain and Switzerland [6]. In this paper we will focus in the Spanish demonstrator. In particular, we will describe the following aspects: The general architecture of the system, paying special attention...

This study investigated how children deploy cues to prominence in a speech task designed to encourage lexical stress shift. The duration, amplitude and F0 of the rhymes in stress-shiftable words were compared in stress clash and non-clash contexts. In adults’ speech, lexical and phrasal prominence patterns reinforced each other and were not sensitive to context. In children’s speech, the promin...

Termination is one of the most interesting problems when dealing with context-sensitive rewrite systems. Although there is a good number of techniques for proving termination of context-sensitive rewriting (CSR), the dependency pair approach, one of the most powerful techniques for proving termination of rewriting, has not been investigated in connection with proofs of termination of CSR. In th...

A Computer-Assisted Pronunciation Training (CAPT) system can provide greater benefit to language learners if it provides not only scoring but also corrective feedback. However, the process of deriving pronunciation error patterns usually requires linguistic knowledge, or large quantities of expensive, annotated, corpora from nonnative speakers. In this paper we explore the possibility of derivi...

This paper presents implemented algorithms for interpreting the meaning of certain context-dependent lexical items within the Ontological Semantic text processing environment. We discuss the form, function and rationale behind three meaning procedures, all of which are, in a certain sense, numerically oriented. We show that only a knowledge-rich processing system can fully interpret such entiti...

Context-sensitive term rewriting is a kind of term rewriting in which reduction is not allowed inside some xed arguments of some function symbols. We introduce two new techniques for proving termination of context-sensitive rewriting. The rst one is a modi cation of the technique of interpretation in a well-founded order, the second one is implied by a transformation in which context-sensitive ...

The focus of this chapter is to present a survey on the most recent advances in representation and analysis of video object trajectories, with application to indexing and retrieval systems. We will review the main methodologies for the description of motion trajectories, as well as the indexing techniques and similarity metrics used in the retrieval process. Strengths and weaknesses of differen...

This paper provides a novel Web image clustering methodology based on their associated texts. In our approach, the semantics of Web images are firstly represented into vectors of term-weight pairs. In order to correctly correlate terms to a Web image, the associated text of the Web image is partitioned into semantic blocks according to the semantic structure of the text with respect to the Web ...

As for any model/theory, a probabilistic seismic hazard analysis (PSHA) model is best tested by comparing its predictions with observations that are independent, e.g. which have not been used for creating the model. Arguably, the most valuable information in the context of seismic hazard analysis is information on long-term hazard, namely maximum intensities (or magnitudes) occuring over time i...

We present an algorithmic scheme for unsupervised cluster ensembles, based on randomized projections between metric spaces, by which a substantial dimensionality reduction is obtained. Multiple clusterings are performed on random subspaces, approximately preserving the distances between the projected data, and then they are combined using a pairwise similarity matrix; in this way the accuracy o...
