Animated characters bring the illusion of life to feature films, television shows, video games, and educational simulations. However, it is difficult for artists to define natural and expressive movement. This challenge is compounded by the fact that people are intrinsically sensitive to subtle inaccuracies in human motion. To address this problem, this thesis presents techniques that adjust ex...

In this paper, we extend the conventional concept of a database as a set of discrete relations to include a set of piecewise continuous functions. We extend the features of Query-by-Example to operations on this piecewise continuous data. Further, we include the concept of iteration in the language, which enhances its capabilities to that of a general programming language. These extensions are ...

We propose a method for joint unsupervised discovery of multiword expressions (MWEs) and their translations from parallel corpora. First, we apply independent monolingual MWE extraction in source and target languages simultaneously. Then, we calculate translation probability, association score and distributional similarity of co-occurring pairs. Finally, we rank all translations of a given MWE ...

Processing queries for databases containing multimedia information is a hard question. In this paper we describe a knowledge base approach to effectively resolve query by examples in image database. We present a prototype system that is at the moment under developing in our Labs. We consider wavelet descriptors for modeling color, shape and texture features, and we propose a knowledge base for ...

We address the problem of classifying multiword expression tokens in running text. We focus our study on Verb-Noun Constructions (VNC) that vary in their idiomaticity depending on context. VNC tokens are classified as either idiomatic or literal. We present a supervised learning approach to the problem. We experiment with different features. Our approach yields the best results to date on MWE c...

This paper summarizes our work for MediaEval 2013 Spoken Web Search task evaluations. The task was Query-by-Example (search of spoken queries within spoken data). We submitted a system composed of 26 subsystems, of which 13 are based on Acoustic Keyword Spotting and 13 on Dynamic Time Warping. All of them use threestate phoneme posteriors as input features. Our main contribution was m-norm norm...

We present a study we conducted to build a repository storing associations between simple dependency treelets in a source language and their corresponding phrases in a target language. To assess the impact of this resource in EBMT, we used the repository to compute coverage statistics on a test bitext and on a nbest list of translation candidates produced by a standard phrase-based decoder.
