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
NEW YORK TIMES BESTSELLER • “A fascinating look at how consumers perceive logos, ads, commercials, brands, and products.”—Time How much do we know about why we buy? What truly influences our decisions in today’s message-cluttered world? In Buyology, Martin Lindstrom presents the astonishing findings from his groundbreaking three-year, seven-million-dollar neuromarketing study—a cutting-edge experiment that peered inside the brains of 2,000 volunteers from all around the world as they encountered various ads, logos, commercials, brands, and products. His startling results shatter much of what we have long believed about what captures our interest—and drives us to buy. Among the questions he explores: • Does sex actually sell? • Does subliminal advertising still surround us? • Can “cool” brands trigger our mating instincts? • Can our other senses—smell, touch, and sound—be aroused when we see a product? Buyology is a fascinating and shocking journey into the mind of today's consumer that will captivate anyone who's been seduced—or turned off—by marketers' relentless attempts to win our loyalty, our money, and our minds.

Book Description
Where can I find the case Simpson v. Satterfield? What are the laws in Nevada on gun ownership? Can you help me apply for a business license? How do I copyright my name? Questions like these make a new law librarian's head spin. The truth is, all librarians are apt to get legal questions, and most struggle to respond. Collection development, too, is tricky if you seldom work with legal publishers. As the law touches more and more of our daily lives while lawyers price their services out of the average person's range, the public increasingly turns to libraries for answers. Where can librarians turn? Okay, that one's easy--to Anthony Aycock s The Accidental Law Librarian.--From publisher description.

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.
