Abstract:

Alors que les sources multimédias sont massivement disponibles en ligne, aider les utilisateurs à comprendre la grande quantité d'information générée est devenu un problème majeur. Une façon de procéder consiste à résumer le contenu multimédia, générant ainsi des versions abrégées et informatives des sources. Cette thèse aborde le sujet du résumé automatique (texte et parole) dans un contexte multilingue. Elle a été réalisée dans le cadre du projet CHISTERA-ANR Accès multilingue à l'information (AMIS). Le résumé multimédia basé sur le texte utilise des transcriptions pour produire des résumés

Abstract:

The Internet constitutes a vast universe of knowledge and human culture, allowing the dissemination of ideas and information without borders. The Web also became an important media for the diffusion of multilingual resources. However, linguistic differences still form a major obstacle to scientific, cultural, and educational exchange. With the ever increasing size of the Web and the availability of more and more documents in various languages, this problem becomes all the more pervasive. Besides this linguistic diversity, a multitude of databases and collections now contain documents in variou

<p>Syftet med denna uppsats är att undersöka problem samt lösningar i relation till informationsåtervinning över språkliga gränser. Metoden som har använts i uppsatsen är studier av forskningsmaterial inom lingvistik samt främst den relativt nya forskningsdisciplinen Cross-Language Information Retrieval (CLIR). I uppsatsen hävdas att världens alla olikartade språk i dagsläget måste betraktas som ett angeläget problem för informationsvetenskapen, ty språkliga skillnader utgör ännu ett stort hinder för den internationella informationsåtervinning som tekniska framsteg, uppkomsten av Internet, dig

Abstract:

The effective transposition of European Union (EU) directives into Member States is important to achieve the policy goals defined in the Treaties and secondary legislation. National Implementing Measures (NIMs) are the legal texts officially adopted by the Member States to transpose the provisions of an EU directive. The measures undertaken by the Commission to monitor NIMs are time-consuming and expensive, as they resort to manual conformity checking studies and legal analysis. In this thesis, we developed a legal information retrieval system using semantic textual similarity techniques to au

Les outils et méthodes d’analyse d’images de documents (DIA) donnent aujourd’hui la possibilité de faire des recherches par mots-clés dans des bases d’images de documents alors même qu’aucune transcription n’est disponible. Dans ce contexte, beaucoup de travaux ont déjà été réalisés sur les OCR ainsi que sur des systèmes de repérage de mots (spotting) dédiés à des documents textuels avec une mise en page simple. En revanche, très peu d’approches ont été étudiées pour faire de la recherche dans des documents contenant du texte multi-orienté et multi-échelle, comme dans les documents graphiques.

This thesis presents a method which reduces the amount of labour required to translate the English question answering dataset SQuAD into Swedish. The purpose of the study is to contribute to shrinking the gap between natural language processing research in English and research in lesser-resourced languages by providing a method for creating datasets in these languages which are counterparts to those used in English. This would allow for the results from English studies to be evaluated in more languages. The method put forward by this thesis uses multilingual sentence embeddings to search for a

Abstract:

Natural Language Processing (NLP) is a field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human languages. One of its most challenging aspects involves enabling computers to derive meaning from human natural language. To do so, several meaning or context representations have been proposed with competitive performance. However, these representations still have room for improvement when working in a cross-domain or cross-language scenario. In this thesis we study the use of knowledge graphs as a cross-domain an

The article describes the research done over a bibliographic database in order to show the impact the specificity of the knowledge organising tools may have on information retrieval. For this purpose two multilingual UDC-based thesauri having different degrees of specificity are considered. Issues of harmonising a classificatory structure with a thesaurus structure are introduced and significant aspects of information retrieval in a multilingual environment are argued in an extensive manner. Aspects of complementarity are discussed with particular emphasis on the real impact produced by altern

Abstract:

Multilingual information retrieval (MLIR) methods generally rely on linguistic resources such as dictionaries, parallel corpora, etc., to overcome the language barrier. For low resource languages without these resources, an alternative approach is to use topical cross-lingual topical correspondence models learned from document-aligned multilingual corpora. However, there is a large and growing corpus of \weakly aligned" text in the form of user-generated content (UGC) data from social networks, commenting widgets, etc. that has been ignored by researchers so far.
