Book Description
Many information professionals working in small units today fail to find the published tools for subject based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject management system, describes the characteristics of some common types of subject tool, and takes the novice step-by-step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval What a thesaurus is used for Why use a thesaurus? Examples of thesauri The structure of a thesaurus Thesaural relations Practical thesaurus construction The vocabulary of the thesaurus Building the systematic structure Conversion to alphabetic format Forms of entry in the thesaurus Maintaining the thesaurus Thesaurus software The wider environment. Readership: Although primarily aimed at the practising information professional, the book is also suitable for students of library and information science.

Book Description
This detailed book is a “how-to” guide to building controlled vocabulary tools, cataloging and indexing cultural materials with terms and names from controlled vocabularies, and using vocabularies in search engines and databases to enhance discovery and retrieval online. Also covered are the following: What are controlled vocabularies and why are they useful? Which vocabularies exist for cataloging art and cultural objects? How should they be integrated in a cataloging system? How should they be used for indexing and for retrieval? How should an institution construct a local authority file? The links in a controlled vocabulary ensure that relationships are defined and maintained for both cataloging and retrieval, clarifying whether a rose window and a Catherine wheel are the same thing, or how pot-metal glass is related to the more general term stained glass. The book provides organizations and individuals with a practical tool for creating and implementing vocabularies as reference tools, sources of documentation, and powerful enhancements for online searching.

Book Description
Explorations in Automatic Thesaurus Discovery presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis, and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb--noun pairings, common expressions, and word family members. The techniques are tested on twenty different corpora ranging from baseball newsgroups, assassination archives, medical X-ray reports, abstracts on AIDS, to encyclopedia articles on animals, even on the text of the book itself. The corpora range from 40,000 to 6 million characters of text, and results are presented for each in the Appendix. The methods described in the book have undergone extensive evaluation. Their time and space complexity are shown to be modest. The results are shown to converge to a stable state as the corpus grows. The similarities calculated are compared to those produced by psychological testing. A method of evaluation using Artificial Synonyms is tested. Gold Standards evaluation show that techniques significantly outperform non-linguistic-based techniques for the most important words in corpora. Explorations in Automatic Thesaurus Discovery includes applications to the fields of information retrieval using established testbeds, existing thesaural enrichment, semantic analysis. Also included are applications showing how to create, implement, and test a first-draft thesaurus.

Book Description
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.

The Thesaurus: Review, Renaissance, and Revision examines the historical development of the thesaurus and the standards employed for thesaurus construction. This book provides both the history of thesauri and tutorials on usage to increase your understanding of thesaurus creation, use, and evaluation. This reference tool offers essential information on thesauri in the digital environment, including Web sites, databases, and software. For 50 years, the thesaurus has been a core reference book; The Thesaurus: Review, Renaissance, and Revision celebrates this history and speculates on the future of vocabulary-switching tools. This book will familiarize you with contemporary and emerging functions of thesauri, including international and multilingual developments.

Book Description
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.
