This book was released on 2005 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ce travail de thèse rentre dans le cadre de l'utilisation des ontologies dans le processus de recherche d'information de manière générale, et plus particulièrement pour une représentation conceptuelle de l'information textuelle (documents/requêtes). Deux principales propositions sont détaillées. La première proposition consiste en une approche de représentation basée sur les réseaux sémantiques et la seconde sur des structures arborescentes. Dans la première approche, DocCore, la projection d'un document sur l'ontologie permet de construire le Noyau Sémantique de Document où les nœuds représentent les concepts "importants" du document et les arcs, une valeur de proximité sémantique entre ces nœuds. Dans la deuxième approche de représentation, DocTree, on exploite la hiérarchie de concepts que procure le lien de subsomption d'une ontologie (is-a) pour décrire un document/requête sous une forme arborescente. Un prototype a été réalisé étayant le bien fondé de ce type d'approche.

Available in PDF, EPUB and Kindle. Book excerpt: L'INA a besoin pour que ses archives audiovisuelles puissent être utilisées de bien connaître le contenu de ses documents. Les documentalistes doivent alors visionner ces documents et les indexer. Afin d'apporter une aide aux documentalistes, nous avons créé un système d'extraction d'information s'appliquant sur des articles de presse écrite. Nous partons de l'hypothèse q'un même événement est, à la fois, décrit dans la presse écrite et visible à la télévision. Nous avons alors concu notre système en nous servant d'une ontologie du domaine pour créer un dictionnaire sémantique et des patrons syntaxico-sémantiques. Nous obtenons, en sortie, des index conceptuels qui pourront être utilisés par les documentalistes lors de l'indexation. Les résultats obtenus sont mitigés : la grande variabilité de la langue dans les articles entra^inent la création d'un nombre important de patrons mais la presse écrite permet d'extraire des informations pertinentes pour l'INA.

Download or read book Geographical Information Retrieval in Textual Corpora written by Christian Sallaberry and published by John Wiley & Sons. This book was released on 2013-07-25 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the field of geographic information extraction and retrieval from textual documents. Geographic information retrieval is a rapidly emerging subject, a trend fostered by the growing power of the Internet and the emerging possibilities of data dissemination. After positioning his work in this field in Chapter 1, the author makes proposals in the following two chapters. Chapter 2 focuses on spatial and temporal information indexing and retrieval in corpora of textual documents. Propositions for both spatial and temporal information retrieval (IR) are made. Chapter 3 tackles the use of generalized spatial and temporal indexes, which are produced from there in the framework of multi-criteria IR. Geographic IR (GIR) is discussed at length, since this IR combines the criteria of spatial, temporal and thematic research. The author provides a rich bibliographical study of the current approaches focused on the modeling and retrieval of spatial and temporal information in textual documents, and similarity measures developed thus far in the literature. The book concludes with a broad perspective of the remaining scientific challenges. Several areas of research are discussed, such as integration of a domain-based ontology, modeling of spatial footprints from the interpretation of spatial relation, and parsing of relations between features deemed relevant within a document resulting from a GIR process. Contents Foreword, Christophe Claramunt. 1. Access by Geographic Content to Textual Corpora: What Orientations ? 2. Spatial and Temporal Information Retrieval in Textual Corpora. 3. Multicriteria Information Retrieval in Textual Corpora. 4. General Conclusion. About the Authors Christian Sallaberry is currently Assistant Professor at the Law, Economics and Management Faculty in Pau, France. His current research interests are in the fields of geographical information retrieval (GIR) in textual corpora: spatial, temporal and thematic information recognition, analyzing, indexing and retrieval. He is interested in spatial, temporal and thematic criteria combinations within a GIR process.

Download or read book Evaluating Systems for Multilingual and Multimodal Information Access written by Thomas Deselaers and published by Springer. This book was released on 2009-09-29 with total page 1026 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ninth campaign of the Cross-Language Evaluation Forum (CLEF) for European languages was held from January to September 2008. There were seven main eval- tion tracks in CLEF 2008 plus two pilot tasks. The aim, as usual, was to test the p- formance of a wide range of multilingual information access (MLIA) systems or s- tem components. This year, 100 groups, mainly but not only from academia, parti- pated in the campaign. Most of the groups were from Europe but there was also a good contingent from North America and Asia plus a few participants from South America and Africa. Full details regarding the design of the tracks, the methodologies used for evaluation, and the results obtained by the participants can be found in the different sections of these proceedings. The results of the CLEF 2008 campaign were presented at a two-and-a-half day workshop held in Aarhus, Denmark, September 17–19, and attended by 150 resear- ers and system developers. The annual workshop, held in conjunction with the European Conference on Digital Libraries, plays an important role by providing the opportunity for all the groups that have participated in the evaluation campaign to get together comparing approaches and exchanging ideas. The schedule of the workshop was divided between plenary track overviews, and parallel, poster and breakout sessions presenting this year’s experiments and discu- ing ideas for the future. There were several invited talks.

Book Synopsis Concepts, Ontologies, and Knowledge Representation by : Grega Jakus
Download or read book Concepts, Ontologies, and Knowledge Representation written by Grega Jakus and published by Springer Science & Business Media. This book was released on 2013-06-22 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recording knowledge in a common framework that would make it possible to seamlessly share global knowledge remains an important challenge for researchers. This brief examines several ideas about the representation of knowledge addressing this challenge. A widespread general agreement is followed that states uniform knowledge representation should be achievable by using ontologies populated with concepts. A separate chapter is dedicated to each of the three introduced topics, following a uniform outline: definition, organization, and use. This brief is intended for those who want to get to know the field of knowledge representation quickly, or would like to be up to date with current developments in the field. It is also useful for those dealing with implementation as examples of numerous operational systems are also given.
Book Synopsis Finding the Concept, Not Just the Word by : Brandy King
Download or read book Finding the Concept, Not Just the Word written by Brandy King and published by Elsevier. This book was released on 2008-08-30 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aimed at students and professionals within Library and Information Services (LIS), this book is about the power and potential of ontologies to enhance the electronic search process. The book will compare search strategies and results in the current search environment and demonstrate how these could be transformed using ontologies and concept searching. Simple descriptions, visual representations, and examples of ontologies will bring a full understanding of how these concept maps are constructed to enhance retrieval through natural language queries. Readers will gain a sense of how ontologies are currently being used and how they could be applied in the future, encouraging them to think about how their own work and their users' search experiences could be enhanced by the creation of a customized ontology. - The authors, a librarian and software consultant, use their expertise to convey both the information science and technical aspects of ontologies and semantic search - Written for librarians. Unlike most work on ontologies which is highly technical and written for professionals in computer science and knowledge management, this text is easy to understand and highlights applications of this technology that are most relevant - Case studies of real life ontologies give a practical look at how they are currently being used
Download or read book Ontologies: written by Dieter Fensel and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ontologies have been developed and investigated for quite a while now in artificial intelligence and natural language processing to facilitate knowledge sharing and reuse. More recently, the notion of ontologies has attracted attention from fields such as intelligent information integration, cooperative information systems, information retrieval, electronic commerce, and knowledge management. The author systematically introduces the notion of ontologies to the non-expert reader and demonstrates in detail how to apply this conceptual framework for improved intranet retrieval of corporate information and knowledge and for enhanced Internet-based electronic commerce. In the second part of the book, the author presents a more technical view on emerging Web standards, like XML, RDF, XSL-T, or XQL, allowing for structural and semantic modeling and description of data and information.

This book was released on 2010-05-11 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: th The purpose of the 11 Conference on Software Engineering, Artificial Intelligence, Networking, and Parallel/Distributed Computing (SNPD 2010) held on June 9 – 11, 2010 in London, United Kingdom was to bring together researchers and scientists, businessmen and entrepreneurs, teachers and students to discuss the numerous fields of computer science, and to share ideas and information in a meaningful way. Our conference officers selected the best 15 papers from those papers accepted for presentation at the conference in order to publish them in this volume. The papers were chosen based on review scores submitted by members of the program committee, and underwent further rounds of rigorous review. In Chapter 1, Cai Luyuan et al. Present a new method of shape decomposition based on a refined morphological shape decomposition process. In Chapter 2, Kazunori Iwata et al. propose a method for reducing the margin of error in effort and error prediction models for embedded software development projects using artificial neural networks (ANNs). In Chapter 3, Viliam Šimko et al. describe a model-driven tool that allows system code to be generated from use-cases in plain English. In Chapter 4, Abir Smiti and Zied Elouedi propose a Case Base Maintenance (CBM) method that uses machine learning techniques to preserve the maximum competence of a system. In Chapter 5, Shagufta Henna and Thomas Erlebach provide a simulation based analysis of some widely used broadcasting schemes within mobile ad hoc networks (MANETs) and propose adaptive extensions to an existing broadcasting algorithm.
