Available in PDF, EPUB and Kindle. Book excerpt: Les ressources d'information multilingues sur le Web sont devenues de plus en plus des objets d'études importantes pour différents domaines intervenant au traitement de l'information. Néanmoins, nous constatons que la structure des ressources multilingues est très peu explorée par rapport à l'abondance des méthodes de traitement automatique des langues naturelles. L'ignorance des structures multilingues pourrait être à l’origine de divers problèmes de performance tels que : i) la redondance, si le site propose simultanément des traductions en plusieurs langues, ii) les parcours bruités lors d’un passage d’une langue à une autre via les vignettes (génération de graphes, conceptuellement, non signifiant), iii) la perte de l’information par la négligence de la spécificité structurelle (même implicite) de chaque langue. Le cadre de cette thèse s’insère dans le cadre des travaux de recherche sur l'extraction semi-automatique (interactive) d'information à partir d’un grand nombre de documents électroniques (essentiellement des documents web) hétérogènes structurées ou semi-structurées. Extraire une information dans ce contexte est défini comme un processus de repérage, formalisation et de traitements des structures de données pouvant comporter d’information pertinente. Dans notre approche nous observons que la structure d’un document Web incorpore des informations qui sont indispensables pour toute démarche d’optimisation de la recherche d’information ou des fouilles de sites web. Pour expérimenter et valider notre propos nous avons développé une méthode d’analyses structurelles concrétisée par le réalisation du système Hyperling. L’objectif direct de ce dernier étant de déterminer, sans aucune connaissance linguistique préalable et explicite, les langues dominantes sur un site Web multilingues. Dans cette thèse, nous abordons l’aspect multilinguisme dans un contexte de catégorisation des sites Web multilingues. Nous apportons quelques connaissances « expérimentales » - issues des travaux de développement et d’expérimentation - portant sur la représentation de documents multilingues, la modélisation des données en une structure homogène, la qualité de la recherche d’information dans un contexte multilingues et enfin sur les notions de frontière et de centre de gravité pour départager des langues dominantes sans puiser dans des connaissances linguistiques.
Download or read book Multi source Multilingual Information Extraction and Summarization written by Thierry Poibeau and published by Springer Science & Business Media. This book was released on 2012-08-14 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information extraction (IE) and text summarization (TS) are powerful technologies for finding relevant pieces of information in text and presenting them to the user in condensed form. The ongoing information explosion makes IE and TS critical for successful functioning within the information society. These technologies face particular challenges due to the inherent multi-source nature of the information explosion. The technologies must now handle not isolated texts or individual narratives, but rather large-scale repositories and streams---in general, in multiple languages---containing a multiplicity of perspectives, opinions, or commentaries on particular topics, entities or events. There is thus a need to adapt existing techniques and develop new ones to deal with these challenges. This volume contains a selection of papers that present a variety of methodologies for content identification and extraction, as well as for content fusion and regeneration. The chapters cover various aspects of the challenges, depending on the nature of the information sought---names vs. events,--- and the nature of the sources---news streams vs. image captions vs. scientific research papers, etc. This volume aims to offer a broad and representative sample of studies from this very active research field.

Available in PDF, EPUB and Kindle. Book excerpt: L'énorme quantité de documents multimédias constamment générés incite au développement de méthodes d'analyse automatique. Dans ce cadre, notre objectif est de faciliter ce processus en extrayant des informations à partir de n'importe quel texte relatif à ces documents. En outre, nous voulons des techniques suffisamment robustes pour traiter des données bruitées et de petite taille. Pour ce faire, nous utilisons des techniques simples nécessitant peu de connaissances externes comme une garantie de robustesse. Plus précisément, nous utilisons des techniques inspirées de la recherche d'information et de l'analyse statistique. Dans cette thèse, nous montrons expérimentalement que des techniques simples, sans connaissance a priori peuvent être utiles pour extraire efficacement les informations à partir du texte. Dans notre cas, ces bons résultats ont été obtenus en choisissant une représentation adaptée pour les données au lieu d'exiger de traitements complexes.
Download or read book Extraction de concepts et de relations entre concepts partir des documents multilingues written by Farah Harrathi and published by . This book was released on 2009 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les travaux menés dans le cadre de cette thèse se situent dans la problématique de recherche- indexation des documents et plus spécifiquement dans celle de l’extraction des descripteurs sémantiques pour l’indexation. Le but de la Recherche d’Information (RI) est de mettre en œuvre un ensemble de modèles et de systèmes permettant la sélection d’un ensemble de documents satisfaisant un besoin utilisateur en termes d’information exprimé sous forme d’une requête. Un Système de Recherche d’Information (SRI) est composé principalement de deux processus. Un processus de représentation et un processus de recherche. Le processus de représentation est appelé indexation, il permet de représenter les documents et la requête par des descripteurs ou des indexes. Ces descripteurs reflètent au mieux le contenu des documents. Le processus de recherche consiste à comparer les représentations des documents à la représentation de la requête. Dans les SRIs classiques, les descripteurs utilisés sont des mots (simples ou composés). Ces SRIs considèrent le document comme étant un ensemble de mots, souvent appelé “ sac de mots ”. Dans ces systèmes, les mots sont considérés comme des graphies sans sémantique. Les seules informations exploitées concernant ces mots sont leurs fréquences d’apparition dans les documents. Ces systèmes ne prennent pas en considération les relations sémantiques entre les mots. Par exemple, il est impossible de trouver des documents représentés par un mot M1 synonyme d’un mot M2, dans le cas où la requête est représentée par M2. Aussi, dans un SRI classique un document indexé par le terme “ bus ” ne sera jamais retrouvé par une requête indexée par le terme “taxi ”, pourtant il s’agit de deux termes qui traitent le même thème “ moyen de transport ”. Afin de remédier à ces limites, plusieurs travaux se sont intéressés à la prise en compte de l’aspect sémantique des termes d’indexation. Ce type d’indexation est appelé indexation sémantique ou conceptuelle.

Download or read book The Semantics of Relationships written by R. Green and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The genesis of this volume was the participation of the editors in an ACMlSIGIR (Association for Computing Machinery/Special Interest Group on Information Retrieval) workshop entitled "Beyond Word Relations" (Hetzler, 1997). This workshop examined a number of relationship types with significance for information retrieval beyond the conventional topic-matching relationship. From this shared participation came the idea for an edited volume on relationships, with chapters to be solicited from researchers and practitioners throughout the world. Ultimately, one volume became two volumes. The first volume, Relationships in the Organization of Knowledge (Bean & Green, 200 I), examines the role of relationships in knowledge organization theory and practice, with emphasis given to thesaural relationships and integration across systems, languages, cultures, and disciplines. This second volume examines relationships in a broader array of contexts. The two volumes should be seen as companions, each informing the other. As with the companion volume, we are especially grateful to the authors who willingly accepted challenges of space and time to produce chapters that summarize extensive bodies of research. The value of the volume clearly resides in the quality of the individual chapters. In naming this volume The Semantics of Relationships: An Interdisciplinary Perspective, we wanted to highlight the fact that relationships are not just empty connectives. Relationships constitute important conceptual units and make significant contributions to meaning.

Download or read book EuroWordNet A multilingual database with lexical semantic networks written by Piek Vossen and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the main objective of EuroWordNet, which is the building of a multilingual database with lexical semantic networks or wordnets for several European languages. Each wordnet in the database represents a language-specific structure due to the unique lexicalization of concepts in languages. The concepts are inter-linked via a separate Inter-Lingual-Index, where equivalent concepts across languages should share the same index item. The flexible multilingual design of the database makes it possible to compare the lexicalizations and semantic structures, revealing answers to fundamental linguistic and philosophical questions which could never be answered before. How consistent are lexical semantic networks across languages, what are the language-specific differences of these networks, is there a language-universal ontology, how much information can be shared across languages? First attempts to answer these questions are given in the form of a set of shared or common Base Concepts that has been derived from the separate wordnets and their classification by a language-neutral top-ontology. These Base Concepts play a fundamental role in several wordnets. Nevertheless, the database may also serve many practical needs with respect to (cross-language) information retrieval, machine translation tools, language generation tools and language learning tools, which are discussed in the final chapter. The book offers an excellent introduction to the EuroWordNet project for scholars in the field and raises many issues that set the directions for further research in semantics and knowledge engineering.

This book was released on 2017-10-24 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multidisciplinary volume offers a systematic analysis of translation and interpreting as a means of guaranteeing equality under the law as well as global perspectives in legal translation and interpreting contexts. It offers insights into new research on • language policies and linguistic rights in multilingual communities • the role of the interpreter • accreditation of legal translators and interpreters • translator and interpreter education in multiple countries and • approaches to terms and tools for legal settings. The authors explore familiar problems with a view to developing new approaches to language justice by learning from researchers, trainers, practitioners and policy makers. By offering multiple methods and perspectives covering diverse contexts (e.g. in Austria, Belgium, England, Estonia, Finland, France, Germany, Hong Kong, Ireland, Norway, Poland), this volume is a welcome contribution to legal translation and interpreting studies scholars and practitioners alike, highlighting settings that have received limited attention, such as the linguistic rights of vulnerable populations, as well as practical solutions to methodological and terminological problems.
Download or read book Parallel Text Processing written by Jean Véronis and published by Springer Science & Business Media. This book was released on 2000-09-30 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the rising importance of multilingualism in language industries, brought about by global markets and world-wide information exchange, parallel corpora, i.e. corpora of texts accompanied by their translation, have become key resources in the development of natural language processing tools. The applications based upon parallel corpora are numerous and growing in number: multilingual lexicography and terminology, machine and human translation, cross-language information retrieval, language learning, etc. The book's chapters have been commissioned from major figures in the field of parallel corpus building and exploitation, with the aim of showing the state of the art in parallel text alignment and use ten to fifteen years after the first parallel-text alignment techniques were developed. Within the book, the following broad themes are addressed: (i) techniques for the alignment of parallel texts at various levels such as sentence, clause, and word; (ii) the use of parallel texts in fields as diverse as translation, lexicography, and information retrieval; (iii) available corpus resources and the evaluation of alignment methods. The book will be of interest to researchers and advanced students of computational linguistics, terminology, lexicography and translation, both in academia and industry.
