Abstract

Il est essentiel pour l'étudiant universitaire ou d'école supérieure d'être capable de repérer rapidement, de manière autonome et critique, des informations valides et de qualité.Basé sur plus de vingt ans d'expérience, ce manuel remplace le manuel "Lire et écrire la littérature scientifique" (Pochet, 2012) qui avait lui-même été construit par la fusion et la mise à jour des livres "Méthodologie documentaire. Rechercher, consulter, rédiger à l'heure d'Internet ?" (Pochet, 2005) et "La rédaction d'un article scientifique. Petit guide pratique adapté aux sciences appliquées et sciences de la vie à l'heure du libre accès" (Pochet, 2009).Les précédents manuels mettaient l'accent sur l'article scientifique, sur le double rôle, de lecteur et d'auteur, des utilisateurs de la littérature scientifique ainsi que sur la nécessité d'une recherche d'information méthodique.Ce manuel ajoute une dimension supplémentaire. Il se focalise sur une bonne compréhension des différents processus en jeux dans la diffusion de l'information scientifique.Les objectifs de cet ouvrage sont d'amener le lecteur, d'une part, à bien comprendre le fonctionnement de la littérature scientifique et ses processus et, d'autre part, maîtriser les méthodes de recherche d'information, de veille informationnelle, de tri, de sélection et d'organisation de l'information ainsi que les méthodes de production d'information scientifique, de citations et de rédaction.

Abstract

Ranking - the algorithmic decision on how relevant an information artifact is for a given information need and the sorting of artifacts by their concluded relevancy - is an integral part of every search engine. In this book we investigate how structured Web data can be leveraged for ranking with the goal to improve the effectiveness of search. We propose new solutions for ranking using on-the-fly data integration and experimentally analyze and evaluate them against the latest baselines.

Abstract

This book explores the development, trends and research of library and information sciences (LIS) in the digital age. Inside, readers will find research and case studies written by LIS experts, educators and theorists, most of whom have visited China, delivered presentations there and drafted their articles based on feedback they received. As a result, readers will discover the LIS issues and concerns that China and the international community have in common.The book first introduces the opportunities and challenges faced by the library and information literacy profession and discusses the key role of librarians in the future of information literacy education. Next, it covers trends in LIS education by examining the vision of the iSchool movement and detailing its practice in Syracuse University.The book then covers issues in information seeking and retrieval by showing how visual data mining technology can be used to detect the relationship and pattern between terms on the Q&A of a social media site. It also includes a case study regarding tracing information seeking behavior and usage on a multimedia website.Next, the book stresses the importance of building an academic accreditation framework for scientific datasets, explores the relationship between bibliometrics and university rankings, and details the birth and development of East Asian Libraries in North America.Overall, the book offers readers insight into the changing nature of LIS, including the electronic dissemination of information, the impact of the Internet on libraries, the changing responsibilities of library professionals, the new paradigm for evaluating information, and characteristics and functions of today's library personnel.

Abstract

Der Erstellungsaufwand multimedialer Lernangebote kann durch die Wiederverwendung bestehender Materialien deutlich reduziert werden. Wie aber kann das Auffinden solcher wiederverwendbaren Lernressourcen unterstützt werden? Der Autor stellt ein Retrieval-Verfahren vor, das SCORM-basierte Informationen zu Lernobjekten und Kursstrukturen entdeckt, analysiert und verwertet. Auf Grundlage dieser Daten werden für Lehrende als auch Lernende hilfreiche Such- und Empfehlungsdienste angeboten.

Abstract

Ontologies and semantic metadata can theoretically solve all problems of traditional full-text search engines. In practice, however, they are always imperfect. This work analyzed whether the negative effect of ontology imperfection is higher than the positive effect of exploiting the ontology features for IR. To answer this question, a complete ontology-based information retrieval system was implemented and thoroughly evaluated.

Abstract

Audio signal processing is a highly active research field where digital signal processing theory meets human sound perception and real-time programming requirements. It has a wide range of applications in computers, gaming, and music technology, to name a few of the largest areas. Successful applications include, for example, perceptual audio coding, digital music synthesizers, and music recognition software. The fact that music is now often listened to using headphones from a mobile device leads to new problems related to background noise control and signal enhancement. Developments in processor technology, such as parallel computing, are changing the way signal-processing algorithms are designed for audio.Topics covered, but were not limited to, the following areas:- Audio signal analysis- Music information retrieval- Enhancement and restoration of audio- Audio equalization and filtering- Audio effects processing- Sound synthesis and modeling- Audio coding- Sound capture and noise control- Sound source separation- Room acoustics and spatial audio- Signal processing for headphones and loudspeakers- High-performance computing in audio
