The research domains of information retrieval and databases have traditionally adopted different approaches to information management. However, in recent years, there has been an increasing cross-fertilization among the two fields and now many research challenges are transversal to them. With this in mind, a winter school was organized in Bressanone, Italy, in February 2013, within the context of the EU-funded research project PROMISE (Participative Research Laboratory for Multimedia and Multilingual Information Systems Evaluation). PROMISE aimed at advancing the experimental evaluation of complex multimedia and multilingual information systems in order to support individuals, commercial entities and communities, who design, develop, employ and improve such complex systems. The overall goal of PROMISE was to deliver a unified environment collecting data, knowledge, tools and methodologies and to help the user community involved in experimental evaluation. This book constitutes the outcome of the PROMISE Winter School 2013 and contains 9 invited lectures from the research domains of information retrieval and databases plus short papers of the best student poster awards. A large variety of topics are covered, including databases, information retrieval, experimental evaluation, metrics and statistics, semantic search, keyword search in databases, semi-structured search, evaluation both in information retrieval and databases, crowdsourcing and social media.

Class-tested and coherent, this textbook teaches classical and web information retrieval, including web search and the related areas of text classification and text clustering from basic concepts. It gives an up-to-date treatment of all aspects of the design and implementation of systems for gathering, indexing, and searching documents; methods for evaluating systems; and an introduction to the use of machine learning methods on text collections. All the important ideas are explained using examples and figures, making it perfect for introductory courses in information retrieval for advanced undergraduates and graduate students in computer science. Based on feedback from extensive classroom experience, the book has been carefully structured in order to make teaching more natural and effective. Slides and additional exercises (with solutions for lecturers) are also available through the book's supporting website to help course instructors prepare their lectures.

Multimedia Information Retrieval: Content-Based Information Retrieval from Large Text and Audio Databases addresses the future need for sophisticated search techniques that will be required to find relevant information in large digital data repositories, such as digital libraries and other multimedia databases. Because of the dramatically increasing amount of multimedia data available, there is a growing need for new search techniques that provide not only fewer bits, but also the most relevant bits, to those searching for multimedia digital data. This book serves to bridge the gap between classic ranking of text documents and modern information retrieval where composite multimedia documents are searched for relevant information. Multimedia Information Retrieval: Content-Based Information Retrieval from Large Text and Audio Databases begins to pave the way for speech retrieval; only recently has the search for information in speech recordings become feasible. This book provides the necessary introduction to speech recognition while discussing probabilistic retrieval and text retrieval, key topics in classic information retrieval. The book then discusses speech retrieval, which is even more challenging than retrieving text documents because word boundaries are difficult to detect, and recognition errors affect the retrieval effectiveness. This book also addresses the problem of integrating information retrieval and database functions, since there is an increasing need for retrieving information from frequently changing data collections which are organized and managed by a database system. Multimedia Information Retrieval: Content-Based Information Retrieval from Large Text and Audio Databases serves as an excellent reference source and may be used as a text for advanced courses on the topic.

This volume celebrates the twentieth anniversary of CLEF - the Cross-Language Evaluation Forum for the first ten years, and the Conference and Labs of the Evaluation Forum since – and traces its evolution over these first two decades. CLEF’s main mission is to promote research, innovation and development of information retrieval (IR) systems by anticipating trends in information management in order to stimulate advances in the field of IR system experimentation and evaluation. The book is divided into six parts. Parts I and II provide background and context, with the first part explaining what is meant by experimental evaluation and the underlying theory, and describing how this has been interpreted in CLEF and in other internationally recognized evaluation initiatives. Part II presents research architectures and infrastructures that have been developed to manage experimental data and to provide evaluation services in CLEF and elsewhere. Parts III, IV and V represent the core of the book, presenting some of the most significant evaluation activities in CLEF, ranging from the early multilingual text processing exercises to the later, more sophisticated experiments on multimodal collections in diverse genres and media. In all cases, the focus is not only on describing “what has been achieved”, but above all on “what has been learnt”. The final part examines the impact CLEF has had on the research world and discusses current and future challenges, both academic and industrial, including the relevance of IR benchmarking in industrial settings. Mainly intended for researchers in academia and industry, it also offers useful insights and tips for practitioners in industry working on the evaluation and performance issues of IR tools, and graduate students specializing in information retrieval.

Stay on top with the latest developments in scientific and technical journal publications! In Scholarly Communication in Science and Engineering Research in Higher Education, experts in the academic community propose cost-effective alternatives to commercial publications in the face of increased journal prices and reduced budgets. This book discusses recent technological innovations that can maintain the needs of researchers who need to stay on the cutting edge of science and technology as well as scholars who must be published and peer-reviewed in order to achieve tenure and promotion. This text also examines the latest developments in information retrieval that will effectively cut time and costs for academic researchers in the library. Scholarly Communication in Science and Engineering Research in Higher Education focuses on the need for the academic community to accept new, economical methods of producing and making available publications such as peer reviews, research papers, letters, technical and experiment reports, preprints, and conference papers. This volume also emphasizes that scientists and engineers—whether graduate students or professionals—must have access to the latest relevant research in their fields and rely on libraries to provide it. Several chapters in this book examine the problem areas of information technology that will need to be fixed, such as bottlenecks to the flow of information, difficulties using information retrieval systems, and the challenges with archiving electronic journals. Using research and case studies, this book offers strategies for obtaining benefits such as: more efficient and inexpensive ways to access and navigate information more cost-effective means of authentication and quality control new initiative programs in electronic theses and dissertations to assist graduate students increased dissemination and access for conference papers at significantly less cost alternative and more effective approaches for solving underlying problems within the scholarly communication circuit of scientists activities for librarians to help expand utilization of digital technologies at the local level accurate and reliable retrieval of citation data from online sources Using Scholarly Communication in Science and Engineering Research in Higher Education, you can play an important role in improving the means and methods in this area of academics. This important guide will help librarians, science and engineering faculty and students, researchers, and publishers maintain funding, improve efficiency, and offer new methods for scientific studies.

This book constitutes the refereed proceedings of the International Conference on Informatics in Secondary Schools - Evolution and Perspectives, ISSEP 2006, held in Vilnius, Lithuania in November 2006. The 29 revised full papers presented were carefully reviewed and selected from 204 submissions. A broad variety of topics related to teaching informatics in secondary schools is addressed.

Knowledge Management was the theme of the Standing Conference of Eastern, Central and Southern African Library and Information Associations (SCECSAL XVII) in 2006. This selection of conference papers provides a cross-disciplinary approach to knowledge, information and development and how the three together can mould a new and more informed society. The challenge is to make our libraries more people-centered and Afro-centric, not simply serving the interests of the elite and paying little attention to the plight of the less well off. This needs to change, with libraries becoming more inclusive and serving the needs of all. These papers raise provocative questions, and provide an insight into the struggle of information services in this part of Africa to be part of an emerging information and knowledge society.
