Download or read book Structures conceptuelles pour la recherche d images sur Internet written by Adrian Popescu and published by . This book was released on 2008 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: La recherche d'images représente une partie importante du nombre total des requêtes sur Internet. Malgré leur utilité et leur popularité, les systèmes de recherche actuels souffrent de certaines limitations, comme le manque de sémantique dans le traitement des requêtes, l'imprécision des résultats, une faible interactivité, ou encore, un manque d'intégration de techniques de traitement d'images. Dans cette thèse, nous démontrons que l'exploitation de structures linguistiques à large échelle représente une réponse viable aux problèmes des systèmes actuels de recherche d'images. Cette thèse est constituée de trois parties : La première partie s'intéresse au cadre de notre étude. Pour commencer, nous essayons de répondre à la question " quelles images cherchons-nous ? " en étudiant un fichier de log qui met en évidence quelques domaines conceptuels importants en recherche d'images, comme les noms communs, les noms géographiques ou les personnalités. Ensuite, nous analysons la relation entre les concepts et leur représentation imagée, puis nous introduisons et définissons les structures linguistiques qui sont le cœur de notre approche. Nous concluons cette première partie par la proposition d'une architecture générique d'un système de recherche d'images intégrant des ressources sémantiques et des fonctionnalités de traitements d'images. La deuxième partie étudie la possibilité d'adapter et/ou de construire automatiquement des structures linguistiques à large échelle pour la recherche d'images sur Internet. Cette tâche est particulièrement ardue car il est nécessaire d'acquérir des connaissances de bonne qualité et d'assurer également une bonne couverture des domaines conceptuels analysés. Notre approche combine la réutilisation de ressources existantes, dans une forme adaptée à la recherche d'images et la structuration de nouvelles connaissances. Nous proposons par exemple un algorithme permettant une extraction totalement automatique d'un thésaurus géographique à partir de sources hétérogènes du Web. Nous proposons plusieurs évaluations permettant de valider notre approche. La troisième partie correspond à la dimension applicative de ce travail avec le développement de trois applications permettant le traitement de requêtes traitant des noms communs, des noms géographiques et des personnalités. Les architectures de ces applications sont des déclinaisons de notre architecture générique présentée dans la première partie. Elles intègrent les nouvelles ressources sémantiques que nous avons produites et proposent une recherche par le contenu dirigée par la sémantique. Ces applications sont décrites, illustrées, puis évaluées par rapport à des systèmes existants.
Download or read book Introduction to Audiovisual Archives written by Peter Stockinger and published by John Wiley & Sons. This book was released on 2013-02-07 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, audiovisual archives and libraries have become very popular especially in the field of collecting, preserving and transmitting cultural heritage. However, the data from these archives or libraries – videos, images, sound tracks, etc. – constitute as such only potential cognitive resources for a given public (or "target community"). They have to undergo more or less significant qualitative transformations in order to become user- or community-relevant intellectual goods. These qualitative transformations are performed through a series of concrete operations such as: audiovisual text segmentation, content description and indexing, pragmatic profiling, translation, etc. These and other operations constitute what we call the semiotic turn in dealing with digital (audiovisual) texts, corpora of texts or even entire (audiovisual) archives and libraries. They demonstrate practically and theoretically the well-known "from data to meta-data" or "from (simple) information to (relevant) knowledge" problem – a problem that obviously directly influences the effective use, the social impact and relevancy and therefore also the future of digital knowledge archives. It constitutes, indeed, the heart of a diversity of important R&D programs and projects all over the world.

Available in PDF, EPUB and Kindle. Book excerpt: Digital preservation is an issue faced by practitioners in Ross Harveythe library and recordkeeping professions, yet most professionalshave little time to keep up with the latest techniquesand standards. This invaluable work provides a single-volume introduction to the principles, strategies and practices currently applied by librarians and recordkeepers to the preservation of digital information and will assist them to make informed decisions about the role of digital information in their care. The book is presented in four parts: Why do we preserve? What do we preserve? How do we preserve? and How do we manage digital preservation? Each part covers the area in detail and addresses current issues in a clear and informative manner. The terminology of the field is explained clearly throughout the book. Each chapter includes a range of case studies from institutionsat the forefront of digital object preservation. An index facilitates quick access. This book will be essential as a professional reference tool for all librarians, recordkeepers and archivists with preservation responsibilities as well as being a definitive source of information for the whole profession including students.

Download or read book Reasoning in Physics written by L. Viennot and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a meaningful understanding of physics, it is necessary to realise that this corpus of knowledge operates in a register different from natural thought. This book aims at situating the main trends of common reasoning in physics with respect to some essential aspects of accepted theory. It analyses a great many research results based on studies of pupils and students at various academic levels, involving a range of physical situations. It shows the impressive generality of the trends of common thought, as well as their resistance to teaching. The book's main focus is to underline to what extent natural thought is organised. As a result of this mapping out of trends of reasoning, some suggestions for teaching are presented; these have already influenced recent curricula in France. This book is intended for teachers and teacher trainers principally, but students can also benefit from it to improve their understanding of physics and of their own ways of reasoning.

Download or read book Habitat Marocain Documents written by Sascha Roesler and published by Park Publishing (WI). This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "Habitat Marocain" housing project was built in Casablanca between 1954-56 by two Swiss architects, Jean Hentsch (1921-84) and André Studer (1926-2007). The complex was part of the reconstruction and expansion scheme for the city under the French colonial administration in Morocco after World War II and meant to house local inhabitants rather than European expatriates. This lead to a culturally specific architectural approach. "Habitat Marocain" is a prime example for the interplay between formal and informal building. This book investigates the contradictions between the architects' cultural assumptions and the actual way of life of inhabitants. It documents the ethnographic influence on the design for the entire dwelling and shows the various transformations to the buildings later made by the residents. The rich material presented, including many photographs by architect André Studer, plans and other documents, illustrates the complex relations between ethnographic imagination, design synthesis and the increasingly informal further development once construction was completed. Habitat Marocain Documents tells the project's entire history from early planning stage to first occupancy and beyond. The book reveals a complex process of research, design, construction, and inhabitation that continues until the present day.

This book was released on 2014-02-26 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le terme promotion de la santé en Afrique, près de 30 ans après l'adoption de la Charte d'Ottawa, continue d'avoir des connotations complètement hors du sens que lui confère cette charte. Cela n'est pas étonnant quand on sait que la notion de santé dans ce contexte africain équivaut à la lutte contre la maladie à travers les soins de santé dispensés par des professionnels de la santé dans des formations sanitaires et les hôpitaux. L'évolution que connait le continent depuis quelques décennies est de donner un peu plus de place à la communauté à travers les relais communautaires dans une participation communautaire vidée de son contenu, car le pouvoir n'est jamais passé entre les mains des communautés.C'est au vu de tout ceci que le présent ouvrage à sa raison d'être pour expliquer les fondements de l'autonomisation communautaire et de la promotion de la santé avec leur importance pour la région africaine en proie aux mauvais indicateurs de santé comparativement aux autres régions du monde.
