Abstract

This book offers a comprehensive and consistent mathematical approach to information retrieval (IR) without which no implementation is possible, and sheds an entirely new light upon the structure of IR models. It contains the descriptions of all IR models in a unified formal style and language, along with examples for each, thus offering a comprehensive overview of them. The book also creates mathematical foundations and a consistent mathematical theory (including all mathematical results achieved so far) of IR as a stand-alone mathematical discipline, which thus can be read and taught independently. Also, the book contains all necessary mathematical knowledge on which IR relies, to help the reader avoid searching different sources. The book will be of interest to computer or information scientists, librarians, mathematicians, undergraduate students and researchers whose work involves information retrieval.

Abstract

Information management (IM) has exploded in importance in recent years and yet until now there has been no Reader to introduce students to the subject. This comprehensive international collection introduces you to the core topics and methodologies used in teaching IM, namely: information behaviour; environmental scanning and decision making; knowledge management; and information strategy. These peer-reviewed papers represent an elite selection from the respected "Information Research" journal, each carefully updated to take into account recent developments. This book is an essential introduction to IM for all students on courses in library and information science, IM, information systems, business information technology, business management, computer science and information technology; as well as for practitioners working in a wide range of organizations providing information services.

Footnote

Rez. in: JASIST 58(2007) no.4, S.607-608 (A.D. Petrou): "One small example of a tension in the book's chapters can be expressed as: What exactly falls under information management (IM) as a domain of study? Is it content and research about a traditional life cycle of information, or is it the latter and also any other important issue in information research, such as culture, virtual reality, and online behavior, and communities of practice? In chapter 13, T.D. Wilson states, "Information management is the management of the life cycle to the point of delivery to the information user" (p. 164), yet as he also recognizes, other aspects of information are now included as IM's study matter. On p. 163 of the same chapter, Wilson offers Figure 12.2, titled "The extended life cycle of information." The life cycle in this case includes the following information stages: acquisition, organization, storage, retrieval, access and lending, and dissemination. All of these six stages Wilson labels, inside the circle, as IM. The rest of the extended information life cycle is information use, which includes use, sharing, and application. Chapter 3's author, Gunilla Widen-Wulff, quoting Davenport (1994), states "effective IM is about helping people make effective use of the information, rather than the machines" (p. 31). Widen-Wulff, however, addresses IM from an information culture perspective. To review the book's critical content, IM definitions and research methodology and methods reported in chapters are critically summarized next. This will provide basic information for anyone interested in using the book as an information research reader.
The chapter by Wilson and Maceviciûtè should have been the first in the book, as it offers an informative, clearly laid out, research-based picture for IM. The chapter offers IM definitions, as mentioned earlier, and also covers a couple of major studies concerned with mapping diversity of content and topics studied in the IM field. RefViz, a visualization tool and an addition to EndNote, was used to map 462 articles published between 1999 and 2004 that had the term information management in their title. Figure 2.1 (Visualization of the IM literature), presents the map's 18 groups or clusters of documents. Two studies by Wilson also are presented. A study completed in 2004 covered the years 2000 to 2004 and reviewed five journals with articles about information activities. The 2004 study analyzed 190 articles from 383 authors. Wilson developed a number of categories about information activities as part of the 2000 and 2004 studies that indicate the scope of the articles analyzed and IM's diversity of subject matter. The remainder of the chapter presents comparative data between the 2000 and 2004 research studies. Joyce Kirk provides a hierarchy of five IM definitions. "IM as IT systems" and "information resource management" are two of these definitions. While it is difficult to clearly recognize any of the hierarchy statements as a definition for IM, what can be had from this hierarchy is the realization, as cviu te' and Wilson state in chapter 2, that IM "is used as an abbreviation for the management of IT, information systems management, management information systems, etc." (p. 20). Perhaps, the critical usefulness of the chapter resides not so much in that it offers any ready to apply definitions for IM but rather in that it provides an overall review about information. The latter can be helpful for a book intended as an information research reader and as an introduction to IM. WidenWulff examined 15 Finnish insurance businesses and developed scales for the measurement of open and closed organizations, and also presented learning organization attributes in different information environments. A 1999 study by Aiki Tibar about critical success factors (CSF) and information needs of successful Estonian companies is the centerpiece of the chapter. The study's findings are presented in relation to previous and more recent research on CSF. The study's methodology was qualitative in nature, involving semistructured interviews with managers and engineers from 25 of the most successful companies in Estonia; these companies were selected in a contest in 1998 as being included in the top 50 most successful companies. In terms of findings, IM was a CFS that was mentioned the most frequently.
