Abstract

The 4th edition of this popular and well-cited text is now co-authored, and includes significant changes from earlier texts. Presenting a comprehensive review of over a century of research on information behavior (IB), this book is intended for students in information studies and disciplines interested in research on information activities. The initial two chapters introduce IB as a multi-disciplinary topic, the 3rd provides a brief history of research on information seeking. Chapter four discusses what is meant by the terms "information" and "knowledge. "Chapter five discusses "information needs," and how they are addressed. The 6th chapter identifies many related concepts. Twelve models of information behavior (expanded from earlier editions) are illustrated in chapter seven. Chapter eight reviews various paradigms and theories informing IB research. Chapter nine examines research methods invoked in IB studies and a discussion of qualitative and mixed approaches. The 10th chapter gives examples of IB studies by context. The final chapter looks at strengths and weaknesses, recent trends, and future development.

Abstract

Throughout most of human history, people got the information they needed for their lives more or less automatically and unthinkingly--through people they talked with, and from their own life experiences. Today, we are inundated with information but often know little about how to find our way through the vast sea of recorded knowledge to get to what we really want and need. In the information sciences researchers have thought a great deal about information seeking, and have studied people in the grip of trying to satisfy an information need. Much has been learned about how to enable comfortable and fun information searching in human, paper, and digital environments. Professor Marcia Bates of UCLA's Department of Information Studies has collected fifteen of her major papers on information searching in theory and practice in this volume. The articles address many aspects of searching for information, including searching tactics and techniques, the "vocabulary problem" in online searching, the kinds of indexing terms to use in various contexts, the Bradford Distribution and its effects on searching in large databases, the true nature of browsing, and how to design computer interfaces for successful searching. For all the variety in types of information systems, the human being interacting with an information source is remarkably stable in psychology and behavior. These human traits and system features are explored in depth in this book. Bates' popular articles, "What is Browsing--Really?" and "The Design of Browsing and Berrypicking Techniques for the Online Search Interface," are included. This is Volume II of three containing selected works by Bates. The others are titled: Information and the Information Professions (Vol. I) and Information Users and Information System Design (Vol. III)

Abstract

Dealing with information is one of the vital skills in the 21st century. It takes a fair degree of information savvy to create, represent and supply information as well as to search for and retrieve relevant knowledge. How does information (documents, pieces of knowledge) have to be organized in order to be retrievable? What role does metadata play? What are search engines on the Web, or in corporate intranets, and how do they work? How must one deal with natural language processing and tools of knowledge organization, such as thesauri, classification systems, and ontologies? How useful is social tagging? How valuable are intellectually created abstracts and automatically prepared extracts? Which empirical methods allow for user research and which for the evaluation of information systems? This Handbook is a basic work of information science, providing a comprehensive overview of the current state of information retrieval and knowledge representation. It addresses readers from all professions and scientific disciplines, but particularly scholars, practitioners and students of Information Science, Library Science, Computer Science, Information Management, and Knowledge Management. This Handbook is a suitable reference work for Public and Academic Libraries.

Abstract

Practical Ontologies for Information Professionals provides an accessible introduction and exploration of ontologies and demonstrates their value to information professionals. More data and information is being created than ever before. Ontologies, formal representations of knowledge with rich semantic relationships, have become increasingly important in the context of today's information overload and data deluge. The publishing and sharing of explicit explanations for a wide variety of conceptualizations, in a machine readable format, has the power to both improve information retrieval and discover new knowledge. Information professionals are key contributors to the development of new, and increasingly useful, ontologies. Practical Ontologies for Information Professionals provides an accessible introduction to the following: defining the concept of ontologies and why they are increasingly important to information professionals ontologies and the semantic web existing ontologies, such as RDF, RDFS, SKOS, and OWL2 adopting and building ontologies, showing how to avoid repetition of work and how to build a simple ontology interrogating ontologies for reuse the future of ontologies and the role of the information professional in their development and use. This book will be useful reading for information professionals in libraries and other cultural heritage institutions who work with digitalization projects, cataloguing and classification and information retrieval. It will also be useful to LIS students who are new to the field.
