Book Description
Cette thèse décrit la conception d’un système de dialogue Homme- Machine pour la recherche d’informations capable d’interagir avec l’utilisateur en langue naturelle en utilisant des stratégies coopératives. Pour étudier les processus dialogiques impliqués dans la recherche d’informations, une méthodologie ascendante a été adoptée. Une série d’expérimentations a permis le recueil de corpus de dialogues humains présentant de telles recherches dans le cadre du système de documentation médicale CISMeF. L’analyse des dialogues recueillis a montré que leur structure correspond bien aux structures sémantiques de l’approche « questionsréponses ». Fondé sur un modèle existant nommé GoDIS, notre système y intègre de nombreux ajouts permettant d’améliorer la cohérence du dialogue et de proposer des exemples, des choix, des assistances. Une implémentation de ce modèle est réalisée et des pistes d’évaluation sont proposées.

Book Description
Many books have indexes, but most textual media have none. Newspapers, legal transcripts, conference proceedings, correspondence, video subtitles, and web pages are increasingly accessible with computers, yet are still without indexes or other sophisticated means of finding the excerpts most relevant to a reader's question. Better than an index, and much better than a keyword search, are the high-precision computerized question-answering systems explored in this book. Marius Pasca presents novel and robust methods for capturing the semantics of natural language questions and for finding the most relevant portions of texts. This research has led to a fully implemented and rigorously evaluated architecture that has produced experimental results showing great promise for the future of internet search technology.

Book Description
This report analyses all aspects of cultural diversity, which has emerged as a key concern of the international community in recent decades, and maps out new approaches to monitoring and shaping the changes that are taking place. It highlights, in particular, the interrelated challenges of cultural diversity and intercultural dialogue and the way in which strong homogenizing forces are matched by persistent diversifying trends. The report proposes a series of ten policy-oriented recommendations, to the attention of States, intergovernmental and non-governmental organizations, international and regional bodies, national institutions and the private sector on how to invest in cultural diversity. Emphasizing the importance of cultural diversity in different areas (languages, education, communication and new media development, and creativity and the marketplace) based on data and examples collected from around the world, the report is also intended for the general public. It proposes a coherent vision of cultural diversity and clarifies how, far from being a threat, it can become beneficial to the action of the international community.

Book Description
The field of narrative (or story) understanding and generation is one of the oldest in natural language processing (NLP) and artificial intelligence (AI), which is hardly surprising, since storytelling is such a fundamental and familiar intellectual and social activity. In recent years, the demands of interactive entertainment and interest in the creation of engaging narratives with life-like characters have provided a fresh impetus to this field. This book provides an overview of the principal problems, approaches, and challenges faced today in modeling the narrative structure of stories. The book introduces classical narratological concepts from literary theory and their mapping to computational approaches. It demonstrates how research in AI and NLP has modeled character goals, causality, and time using formalisms from planning, case-based reasoning, and temporal reasoning, and discusses fundamental limitations in such approaches. It proposes new representations for embedded narratives and fictional entities, for assessing the pace of a narrative, and offers an empirical theory of audience response. These notions are incorporated into an annotation scheme called NarrativeML. The book identifies key issues that need to be addressed, including annotation methods for long literary narratives, the representation of modality and habituality, and characterizing the goals of narrators. It also suggests a future characterized by advanced text mining of narrative structure from large-scale corpora and the development of a variety of useful authoring aids. This is the first book to provide a systematic foundation that integrates together narratology, AI, and computational linguistics. It can serve as a narratology primer for computer scientists and an elucidation of computational narratology for literary theorists. It is written in a highly accessible manner and is intended for use by a broad scientific audience that includes linguists (computational and formal semanticists), AI researchers, cognitive scientists, computer scientists, game developers, and narrative theorists.

Book Description
ARIST, published annually since 1966, is a landmark publication within the information science community. It surveys the landscape of information science and technology, providing an analytical, authoritative, and accessible overview of recent trends and significant developments. The range of topics varies considerably, reflecting the dynamism of the discipline and the diversity of theoretical and applied perspectives. While ARIST continues to cover key topics associated with "classical" information science (e.g., bibliometrics, information retrieval), editor Blaise Cronin is selectively expanding its footprint in an effort to connect information science more tightly with cognate academic and professional communities. Contents of Volume 40 (2006): SECTION I: Information and Society Chapter 1: The Micro- and Macroeconomics of Information, Sandra Braman Chapter 2: The Geographies of the Internet, Matthew Zook Chapter 3: Open Access, M. Carl Drott SECTION II: Technologies and Systems Chapter 4: TREC: An Overview, Donna K. Harman and Ellen M. Voorhees Chapter 5: Semantic Relations in Information Science, Christopher S. G.

Book Description
In this engrossing book, Hollis Clayson provides the first description and analysis of French artistic interest in women prostitutes, examining how the subject was treated in the art of the 1870s and 1880s by such avant-garde painters as Cézanne, Degas, Manet, and Renoir, as well as by the academic and low-brow painters who were their contemporaries. Clayson not only illuminates the imagery of prostitution-with its contradictory connotations of disgust and fascination-but also tackles the issues and problems relevant to women and men in a patriarchal society. She discusses the conspicuous sexual commerce during this era and the resulting public panic about the deterioration of social life and civilized mores. She describes the system that evolved out of regulating prostitutes and the subsequent rise of clandestine prostitutes who escaped police regulation and who were condemned both for blurring social boundaries and for spreading sexual licentiousness among their moral and social superiors. Clayson argues that the subject of covert prostitution was especially attractive to vanguard painters because it exemplified the commercialization and the ambiguity of modern life.
