  Abstract: Information retrieval is a communication process that links the information user to a librarian, museum curator, fingerprint identification specialist, or whoever is in charge of a collection of what we are calling documents. The communication will normally involve the processing of text, strings of words known to both parties in the process, that can be used to describe a document's content and other attributes and link it with a need expressed in similar terms. This 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. The first edition of this work appeared just before the World Wide Web came on the scene, but was nonetheless a student favorite because of its clarity. The new edition is updated and expanded, covering not only the Web but also new developments in how IR systems are or could be designed.

  Yuan, W. ; Meadow, C.T.: ¬A study of the use of variables in information retrieval user studies.
  In: Journal of the American Society for Information Science. 50(1999) no.2, S.140-150.
  
  Abstract: This article reports on an exploratory study of the measurement of commonality in the use of variables or measures by authors and groups of authors who have reported on studies of information retrieval system users. There is some similarity to co-citation analysis in that, when 2 individual papers, or 2 authors of sveral works, use the same variables, this indicates a similarity in approach to the subject. Such usage may be a stroger indication of similarity than co-citation be cause it represents what the authors did, rather than what they say

  Meadow, C.T.: ¬A proposed method of measuring the utility of individual information retrieval tools.
  In: Canadian journal of information and library science. 21(1996) no.1, S.22-34.
  
  Abstract: Proposes a new method of evaluating information retrieval systems by concentrating on individual tools in the context of their use, rather than systems as a whole. A tool is a command, its menu or graphic interface equivalent, or a move or stratagem. A user would render an assessment of the relative success of a small part of a search, and every tool used in that part would be credited with a contribution to the result, whether positive or negative. The cumulative scores would provide an assessment of the overall utility of the tool

  Abstract: Attemps to define the term: information; and challenges the assumptions often made about familiar concepts used in evaluating information services. Comments on the fact that do not always report the definitions of the variables they measure, or the circumstances of the measurement, with enough precision to enable others to use them. Illustrates the points with particular reference to the ambiguity evident in the use of the term 'relevance' when applied to information and notes the difficulty in sharing data among information science researchers in the absence of agreed upon standards

  Meadow, C.T.: Speculations on the measurement and use of user characteristics in information retrieval experimentation.
  In: Canadian journal of information and library science. 19(1994) no.4, S.1-22.
  
  Abstract: Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

  Abstract: Reports on the design and implementation of the information searching and retrieval software, PBS (Parsing, Boolean recognition, Stemming) for the front end OAK 2, a new version of OAK developed at Toronto Univ. OAK 2 is a research tool for user behaviour studies. PBS receives natural language search statements from an end user and identifies search facets and implied Boolean logic operators

  Marchionini, G. ; Meadow, C.T. ; Dwiggins, S. ; Lin, X. ; Jiabin, W. ; Yuan, W.: ¬A study of user interaction with information retrieval interfaces : progress report.
  In: Canadian journal of information science. 16(1991) no.4, S.42-59.
  
  Abstract: Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

  Meadow, C.T. ; Cerny, B.A. ; Borgman, C.L. ; Case, D.O.: Online access to knowledge : system design.
  In: Journal of the American Society for Information Science. 40(1989), S.86-98.
  
  Abstract: The project online access to knowledge (OAK) has developed a computer intermediary for delected users of the Department of Energy's DOE/RECON and BASIS online information retrieval systems. Its purpose is to enable people who have little or no training or experience in bibliographic searching to conduct their own searches, without the assistance of a trained librarian. hence permitting the user to work in both a place and time of his or her choosing. The purpose of this article is to report on the design and the rationale for the design. OAK software consists of both a tutorial and an assistance program. The latter does not employ a command language, hence obviates the need for a searcher to learn the formal language usually associated with an online database search service. It is central to our approach that this system does not supplant the user's ultimate primacy in knowing what he or she is looking for, nor in judging the results
