Abstract

Aimed at students and professionals within Library and Information Services (LIS), this book is about the power and potential of ontologies to enhance the electronic search process. The book will compare search strategies and results in the current search environment and demonstrate how these could be transformed using ontologies and concept searching. Simple descriptions, visual representations, and examples of ontologies will bring a full understanding of how these concept maps are constructed to enhance retrieval through natural language queries. Readers will gain a sense of how ontologies are currently being used and how they could be applied in the future, encouraging them to think about how their own work and their users' search experiences could be enhanced by the creation of a customized ontology. Key Features Written by a librarian, for librarians (most work on ontologies is written and read by people in computer science and knowledge management) Written by a librarian who has created her own ontology and performed research on its capabilities Written in easily understandable language, with concepts broken down to the basics The Author Ms. King is the Information Specialist at the Center on Media and Child Health at Children's Hospital Boston. She is a graduate of Smith College (B.A.) and Simmons College (M.L.I.S.). She is an active member of the Special Libraries Association, and was the recipient of the 2005 SLA Innovation in Technology Award for the creation of a customized media effects ontology used for semantic searching. Readership The book is aimed at practicing librarians and information professionals as well as graduate students of Library and Information Science.

Abstract

After 25 years of service, this professional text has been updated in line with developments in the field of library science. Since the seventh edition of this standard text was published in 1985, there have been changes in virtually every area of bibliographic control. "AACR2 Revised" (AACR2R) has been implemented; new editions of or supplements to LCSH, LC classification, and DDC, and "Sears" have appeared; OCLC has adopted the PRISM format; and networking and online catalogues have become a way of life. Taylor addresses these and other changes in this edition. Consequently, many chapters of this text are entirely new, such as "Cataloguing in Context" and "Subject Arrangement of Library Materials", or fully revised such as "Development of Cataloguing Codes", which has been expanded to show the continuity in the development leading to publication of AACR2R. Two appendices have been added: an introduction to USMARC format and instructions for typing catalogue cards, including a detailed analysis of the punctuation and spacing to be used when conforming to the International Standard Bibliographic Description (ISBD).

Abstract

More and more libraries, archives, and museums are creating online collections of digitized resources. Where can those charged with organizing these new collections turn for guidance on the actual practice of metadata design and creation? "Metadata for Digital Collections: A How-to-do-it Manual" is suitable for libraries, archives, and museums. This practical, hands-on volume will make it easy for readers to acquire the knowledge and skills they need, whether they use the book on the job or in a classroom. Author Steven Miller introduces readers to fundamental concepts and practices in a style accessible to beginners and LIS students, as well as experienced practitioners with little metadata training. He also takes account of the widespread use of digital collection management systems such as CONTENTdm. Rather than surveying a large number of metadata schemes, Miller covers only three of the schemes most commonly used in general digital resource description, namely, Dublin Core, MODS, and VRA. By limiting himself, Miller is able to address the chosen schemes in greater depth. He is also able to include numerous practical examples that clarify common application issues and challenges. He provides practical guidance on applying each of the Dublin Core elements, taking special care to clarify those most commonly misunderstood. The book includes a step-by-step guide on how to design and document a metadata scheme for local institutional needs and for specific digital collection projects. The text also serves well as an introduction to broader metadata topics, including XML encoding, mapping between different schemes, metadata interoperability and record sharing, OAI harvesting, and the emerging environment of Linked Data and the Semantic Web, explaining their relevance to current practitioners and students. Each chapter offers a set of exercises, with suggestions for instructors. A companion website includes additional practical and reference resources.

Abstract

Metadata research has emerged as a discipline cross-cutting many domains, focused on the provision of distributed descriptions (often called annotations) to Web resources or applications. Such associated descriptions are supposed to serve as a foundation for advanced services in many application areas, including search and location, personalization, federation of repositories and automated delivery of information. Indeed, the Semantic Web is in itself a concrete technological framework for ontology-based metadata. For example, Web-based social networking requires metadata describing people and their interrelations, and large databases with biological information use complex and detailed metadata schemas for more precise and informed search strategies. There is a wide diversity in the languages and idioms used for providing meta-descriptions, from simple structured text in metadata schemas to formal annotations using ontologies, and the technologies for storing, sharing and exploiting meta-descriptions are also diverse and evolve rapidly. In addition, there is a proliferation of schemas and standards related to metadata, resulting in a complex and moving technological landscape - hence, the need for specialized knowledge and skills in this area. The Handbook of Metadata, Semantics and Ontologies is intended as an authoritative reference for students, practitioners and researchers, serving as a roadmap for the variety of metadata schemas and ontologies available in a number of key domain areas, including culture, biology, education, healthcare, engineering and library science.

Resonanz: "Arlene Taylor and her compadres don't even try to teach you how to construct a hierarchical record. Instead, they direct their efforts toward showcasing what's possible when digital technology and traditional cataloging practice meet. This is the future of cataloging." - Library Media Connection "The emergence of this textbook is testimony to the breadth and depth of work done to date. It documents much of that work, and provides a good basic introduction to FRBR that is broadly understandable... The relational concepts within FRBR are complicated and can be challenging. This book does a good job of illuminating them in a straightforward manner. It also describes how the application of the FRBR concepts could improve our systems of bibliographic access in very specific ways... For those of us that really want or need to be able to predict the impact that FRBR will have on our work, this is an accessible explanation of the current state of the art. As such it is a real contribution to our understanding." - TechKNOW "Understanding FRBR... features chapters contributed by leading authorities in the cataloging field... It offers a basic introduction to FRBR, discussions about FRBR, FRAD (functional requirements for authority data), and RDA (resource description and access), and the issues involved in using FRBR in nontraditional library settings such as with cartographic materials and music. Both books are well illustrated and include numerous bibliographical resources.' [Reviewed in conjuntion with FRBR: A Guide for the Perplexed]." - Library Journal "Taylor and her contributors cover FRBR and introduce the reader to FRAD as well... All chapters conclude with current and useful references to further reading and more information." - Booklist "Understanding FRBR is clearly written, well illustrated (many of the concepts are clarified by very helpful diagrams), and well indexed; additionally, chapters feature extensive bibliographies, many of which provide URLs to the IFLA groups' documents. While it may seem that this book is of interest only to catalogers, the application of FRBR will change the structure of catalog and the systems used to store and display it; therefore, it is an important text for systems librarians, reference librarians, and anybody else interested in the future of the organization and display of bibliographic information." - College & Research Libraries "Understanding FRBR is a useful and timely book that brings together recent developments in FRBR and offers several assessments of it." - Technicalities "No cataloguer, bibliographic systems designer or library and information science lecturers and students should be without this book. It is a useful resource in acquiring an understanding of what FRBR is about and how it will change the way in which cataloguers will think about cataloguing in future." - The Electronic Library
