      Automated Information Retrieval

      Theory and Methods

      by Valery J. Frants, Jacob Shapiro, Vladimir G. Voiskunskii

      Automated Information Retrieval" describes a fully automated Boolean System and gives special attention to theoretical problems in automatic retrieval of textual information. The book details algorithms in each process in the system, including those that are radically new in the retrieval process and those that are adaptable to the individual. New approaches to evaluating information retrieval systems and studying their performance are included. This book reviews the general principles of constructing any system, such as an information retrieval system. It provides a detailed analysis of basic concepts such as information need, information, information crisis, and the notation of information retrieval. It examines the goal, function, structure, and language of an information retrieval system. It describes the construction of an information retrieval system (methods, algorithms, and approaches). It details different approaches to evaluating the results of information retrieval. It features new directions in the development of information retrieval systems.

      Information Tasks

      Toward a User-centered Approach to Information Systems

      by Bryce Allen

      The user-centered approach is central to the creation of usable information systems, services, and institutions. Information system design should derive from user research into information needs, tasks accomplished in meeting those needs, and resources used in the tasks. "Information Tasks" summarizes user research, then presents design sketches of systems that illustrate how design is linked to research. Also discussed are usable information services and an overview of the organization and economics of information institutions. This comprehensive user-centered approach provides an agenda for information research, design, and education that challenges many accepted beliefs and suggests new directions for information work. "Information Tasks" is of interest to library and information science students and faculty interested in information storage and retrieval, user studies, and systems analysis design. Students and scholars of human factors in systems design, human-computer interaction, and cognitive engineering also find the text useful. It reviews user research from many disciplines, and links research to practical design issues. It provides a unified model for user studies and user-centered design, and includes how-to summaries of design chapters. It shows how designers can investigate their user communities. It provides a general template for the design process. It integrates all aspects of information design, and discusses library issues in the larger information context.

      Library Technical Services

      Operations and Management

      by Irene P. Godden

      This revised Second Edition addresses developments that have transformed library operations in the recent past. In the technical services administration chapter, there is a new section on leadership and management style, strategic planning, managerial accounting, and output measures. The bibliography has been expanded to include more management literature. At the same time, in the automation chapter, expanded sections on downloading bibliographic data into personal files, full text-access, and implications for libraries of the emerging high-speed electronic highways for scholarly information, that is, regional networks linked by the internet, and the emerging NREN (National Research and Education Network), have been added. The entire acquisitions chapter has been reordered to reflect new approaches to acquisitions work in an automated environment and the chapter on bibliographic control has been refocused to emphasize the online environment, and to reflect recent developments in cataloguing tools and rules. Because there has been a tremendous increase in preservation-related activities in the last ten years or so, the preservation chapter has been expanded, with a concurrent shift in emphasis from materials processing to preservation.

      Text Information Retrieval Systems

      by Charles T. Meadow, Bert R. Boyce, Donald H. Kraft, Carol L Barry

      This will be the third edition of the highly successful "Text Information Retrieval Systems". The book's purpose is to teach people who will be searching or designing text retrieval systems how the systems work. For designers, it covers problems they will face and reviews currently available solutions to provide a basis for more advanced study. For the searcher its purpose is to describe why such systems work as they do. The book is primarily about computer-based retrieval systems, but the principles apply to nonmechanized ones as well. The book covers the nature of information, how it is organized for use by a computer, how search functions are carried out, and some of the theory underlying these functions. As well, it discusses the interaction between user and system and how retrieved items, users, and complete systems are evaluated. A limited knowledge of mathematics and of computing is assumed. This third edition will be updated to include coverage of the WWW and current search engines. In many cases, examples of non-web searching will be replaced with web-based illustrations. Coverage of interfaces, various features available to assist searchers, and areas in which search assistance is not available will also be covered. In addition, the book will have a web dimension which will include relevant material available online, to be used in conjunction with the text. It is a follow-up to the award winning 2nd Edition. It focuses on computer-based system but basic principles can be applied to any information seeking context.

      Using Subject Headings for Online Retrieval

      Theory, Practice and Potential

      by Karen Markey Drabenstott, Diane Vizine-Goetz

      Using Subject Headings for Online Retrieval" is an indispensable tool for online system designers who are grappling with developing new systems or refining existing ones. This ready reference describes subject analysis and subject searching in online catalogs, including the limitations of retrieval, and demonstrates how such limitations can be overcome through system design and programming. The practical reference also describes the Library of Congress Subject Headings (LCSH) system and system characteristics; it shows how information is stored in machine-readable files; and it offers examples of and recommendations for successful retrieval methods. Tables are included to support these recommendations, and diagrams, graphs, and bar charts are used to provide results of data analysis. Practitioners in institutions using or considering the installation of an online catalog will continuously consult this book to generate specifications. The book also appeals to researchers in library systems, information retrieval, and user behavior because it details the results of an extensive, empirical study of the subject terms entered into online systems by end users. It also addresses the needs of advanced students in library schools and instructors in library automation, information retrieval, cataloging, indexing, and user behavior. It overviews the LCSH system and system characteristics. It describes how information is stored in machine-readable files. It offers examples of and recommendations for successful retrieval methods. Empirical evidence supports recommendations.

      Looking for Information

      A Survey of Research on Information Seeking, Needs, and Behavior

      by Jens-Erik Mai, Donald O. Case, Lisa M. Given

      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.
