Book Description
La fouille de textes est une activité combinant traitements informatiques et données linguistiques avec comme objectif principal l’extraction et l’organisation automatique des informations présentes dans les textes. Deux familles de méthodes permettent d’atteindre ce but : celles à base de connaissances d’experts et celles reposant sur un apprentissage automatique supervisé. Une campagne d’évaluation consiste à confronter les systèmes développés par plusieurs équipes sur un même jeu de données et en un temps limité. Créé en 2005 à l’image des campagnes anglo-saxonnes, le défi fouille de textes (DEFT) est aujourd’hui la seule campagne d’évaluation francophone en fouille de textes. Cet ouvrage rassemble les méthodes utilisées lors des différentes éditions du défi. Les thématiques relèvent de la classification de documents en genres et thèmes, de la fouille d’opinions et de l’identification de la période de parution d’un document.

Book Description
SCIENCE AND EMPIRES: FROM THE INTERNATIONAL COLLOQUIUM TO THE BOOK Patrick PETITJEAN, Catherine JAMI and Anne Marie MOULIN The International Colloquium "Science and Empires - Historical Studies about Scientific De velopment and European Expansion" is the product of an International Colloquium, "Sciences and Empires - A Comparative History of Scien tific Exchanges: European Expansion and Scientific Development in Asian, African, American and Oceanian Countries". Organized by the REHSEIS group (Research on Epistemology and History of Exact Sciences and Scientific Institutions) of CNRS (National Center for Scientific Research), the colloquium was held from 3 to 6 April 1990 in the UNESCO building in Paris. This colloquium was an idea of Professor Roshdi Rashed who initiated this field of studies in France some years ago, and proposed "Sciences and Empires" as one of the main research programmes for the The project to organize such a colloquium was a bit REHSEIS group. of a gamble. Its subject, reflected in the title "Sciences and Empires", is not a currently-accepted sub-discipline of the history of science; rather, it refers to a set of questions which found autonomy only recently. The terminology was strongly debated by the participants and, as is frequently suggested in this book, awaits fuller clarification.

Book Description
This book provides the readers with retrospective and prospective views with detailed explanations of component technologies, speech recognition, language translation and speech synthesis. Speech-to-speech translation system (S2S) enables to break language barriers, i.e., communicate each other between any pair of person on the glove, which is one of extreme dreams of humankind. People, society, and economy connected by S2S will demonstrate explosive growth without exception. In 1986, Japan initiated basic research of S2S, then the idea spread world-wide and were explored deeply by researchers during three decades. Now, we see S2S application on smartphone/tablet around the world. Computational resources such as processors, memories, wireless communication accelerate this computation-intensive systems and accumulation of digital data of speech and language encourage recent approaches based on machine learning. Through field experiments after long research in laboratories, S2S systems are being well-developed and now ready to utilized in daily life. Unique chapter of this book is end-2-end evaluation by comparing system’s performance and human competence. The effectiveness of the system would be understood by the score of this evaluation. The book will end with one of the next focus of S2S will be technology of simultaneous interpretation for lecture, broadcast news and so on.

Book Description
All current methods of secure communication such as public-key cryptography can eventually be broken by faster computing. At the interface of physics and computer science lies a powerful solution for secure communications: quantum cryptography. Because eavesdropping changes the physical nature of the information, users in a quantum exchange can easily detect eavesdroppers. This allows for totally secure random key distribution, a central requirement for use of the one-time pad. Since the one-time pad is theoretically proven to be undecipherable, quantum cryptography is the key to perfect secrecy. Quantum Communications and Cryptography is the first comprehensive review of the past, present, and potential developments in this dynamic field. Leading expert contributors from around the world discuss the scientific foundations, experimental and theoretical developments, and cutting-edge technical and engineering advances in quantum communications and cryptography. The book describes the engineering principles and practical implementations in a real-world metropolitan network as well as physical principles and experimental results of such technologies as entanglement swapping and quantum teleportation. It also offers the first detailed treatment of quantum information processing with continuous variables. Technologies include both free-space and fiber-based communications systems along with the necessary protocols and information processing approaches. Bridging the gap between physics and engineering, Quantum Communications and Cryptography supplies a springboard for further developments and breakthroughs in this rapidly growing area.

Book Description
This volume brings together evidence for the cognitive, social, and technological foundations necessary for the development of hafting, or the addition of handles and shafts to previously hand-held tools, which made the tools not only more efficient, but improved their makers' chances of survival.

Book Description
The extraordinary fecundity of the photographic medium between the first and second world wars can be persuasively attributed to the dynamic circulation of people, of ideas, of images, and of objects that was a hallmark of that era in Europe and the United States. Voluntary and involuntary migration, a profusion of publications distributed and read on both sides of the Atlantic, and landmark exhibitions that brought artistic achievements into dialogue with one another all contributed to a period of innovation that was a creative peak both in the history of photography and in the field of arts and letters. Few, if any, collections of photography capture the imaginative spirit of this moment as convincingly as the Thomas Walther Collection at The Museum of Modern Art.0This volume represents an important chapter in the rich and complex lives of these works, providing ample evidence of the brilliance of the photographers practicing on both sides of the Atlantic in the interwar period.00Exhibition: Museo d'arte della Svizzera italiana, Lugano, Switzerland (25.04-01.08.2021) / Jeu de Paume, Paris, France (14.09.2021-30.01.2022) / CAMERA, Turin, Italy (03-06.2022).

Book Description
The 1990s saw a paradigm change in the use of corpus-driven methods in NLP. In the field of multilingual NLP (such as machine translation and terminology mining) this implied the use of parallel corpora. However, parallel resources are relatively scarce: many more texts are produced daily by native speakers of any given language than translated. This situation resulted in a natural drive towards the use of comparable corpora, i.e. non-parallel texts in the same domain or genre. Nevertheless, this research direction has not produced a single authoritative source suitable for researchers and students coming to the field. The proposed volume provides a reference source, identifying the state of the art in the field as well as future trends. The book is intended for specialists and students in natural language processing, machine translation and computer-assisted translation.
