AbstractRecent work in several computational linguistics (CL) applications (especially question answering) has shown the value of semantics (in fact, many people argue that the current performance ceiling experienced by so many CL applications derives from their inability to perform any kind of semantic processing). But the absence of a large …...

AbstractThis paper presents an on-going project aiming at enhancing the OPAC (Online Public Access Catalog) search system of the Library of the Free University of Bozen-Bolzano with multilingual access. The Multilingual search system (MUSIL), we have developed, integrates advanced linguistic technologies in a user friendly interface and bridges the gap …...

AbstractThis paper describes a featurized functional dependency corpus automatically derived from the Penn Treebank. Each word in the corpus is associated with over three dozen features describing the functional syntactic structure of a sentence as well as some shallow morphology. The corpus was created for use in probabilistic surface generation, …...

AbstractWe present here the choices which were made within the framework of three oral corpora projects: Socio-linguistics studies on Orleans (ESLO), Phonology of the Contemporary French (PFC), the Archivage corpus of the LACITO lab. This comparative presentation of three corpora of audio linguistic resources comes from a analysis about the …...

AbstractIn this paper, process of the Czech Lombard Speech Database (CLSD'05) acquisition is presented. Feature analyses have proven a strong appearance of Lombard effect in the database. In the small vocabulary recognition task, significant performance degradation was observed for the Lombard speech recorded in the database. Aim of this paper …...

AbstractThis poster is a preliminary report of our experiments for detecting semantically shifted terms between different domains for the purposes of new concept extraction. A given term in one domain may represent a different concept in another domain. In our approach, we quantify the degree of similarity of words between …...

AbstractOne of the most critical components in the process of building automatic speech recognition (ASR) capabilities for a new language is the lexicon, or pronouncing dictionary. For practical reasons, it is desirable to manually create only the minimal lexicon using available native-speaker phonetic expertise and, then, use the resulting seed …...

AbstractWe describe and compare different methods for creating a dictionary of words with their corresponding semantic orientation (SO). We tested how well different dictionaries helped determine the SO of entire texts. To extract SO for each individual word, we used a common method based on pointwise mutual information. Mutual information …...

AbstractWe present a formalism capable of searching and optionally replacing forests of subtrees within labelled trees. In particular, the formalism is developed to process linguistic treebanks. When used as a substitution tool, the interpreter processes rewrite rules consisting of left and right side. The left side specifies a forest of …...

AbstractWe present here an open-source software platform for the integration of speech translation components. This tool is useful to integrate into a common framework different automatic speech recognition, spoken language translation and text-to-speech synthesis solutions, as demonstrated in the evaluation of the European LC-STAR project, and during the development of …...

AbstractThis paper is concerned with the fundamentals of multidimensional dialogue act annotation, i.e. with what it means to annotate dialogues with information about the communicative acts that are performed with the utterances, taking various 'dimensions' into account. Two ideas seem to be prevalent in the literature concerning the notion of …...

AbstractThis article presents a set of morphological tools for six small endangered minority languages belonging to the Uralic language family, Udmurt, Komi, Eastern Mari, Northern Mansi, Tundra Nenets and Nganasan. Following an introduction to the languages, the two sets of tools used in the project (MorphoLogic's Humor tools and the …...

AbstractThe newly founded European Centre of Excellence for Speech Synthesis (ECESS) is an initiative to promote the development of the European research area (ERA) in the field of Language Technology. ECESS focuses on the great challenge of high-quality speech synthesis which is of crucial importance for future spoken-language technologies. The …...

AbstractThe primary aim of the project SENSEM (Sentence Semantics, BFF2003-06456) is the construction of a Lexical Data Base illustrating the syntactic and semantic behavior of each of the senses of the 250 most frequent verbs of Spanish. With this objective in mind, we are currently building an annotated corpus consisting …...

AbstractEvaluation of automatic translation output is a difficult task. Several performance measures like Word Error Rate, Position Independent Word Error Rate and the BLEU and NIST scores are widely use and provide a useful tool for comparing different systems and to evaluate improvements within a system. However the interpretation of …...

AbstractTranslation In this work we investigate new possibilities for improving the quality of statistical machine translation (SMT) by applying word reorderings of the source language sentences based on Part-of-Speech tags. Results are presented on the European Parliament corpus containing about 700k sentences and 15M running words. In order to investigate …...

AbstractA major barrier to the development of accurate and realistic models of human emotions is the absence of multi-cultural / multilingual databases of real-life behaviours and of a federative and reliable annotation protocol. QUB and LIMSI teams are working towards the definition of an integrated coding scheme combining their complementary …...

AbstractIMORPHĒ is a significantly extended version of MORPHE, a morphology description compiler. MORPHE’s morphology description language is based on two constructs: 1) a morphological form hierarchy, whose nodes relate and differentiate surface forms in terms of the common and distinguishing inflectional features of lexical items; and 2) transformational rules, attached …...

AbstractIn this paper we discuss the way of evaluating topic segmentation, from mathematical measures on variously constructed reference corpus to contextual evaluation depending on different topic segmentation usages. We present an overview of the different ways of building reference corpora and of mathematically evaluating segmentation methods, and then we focus …...

AbstractIn this paper we will focus on corpora as a resource for researching language processing for terminological purposes. Based on the TEI guide, we present the templates used to tag our TxtCeram corpus and its features when working with WordSmith, a text analysis tool. We present an experiment for studying …...
