This study investigated through empirical methods the extent to which information acquisition and information management capacity of administrators in tertiary institutions in South-Western Nigeria contributed to their decision-making effectiveness. It adopted the ex post facto survey research design, using the random sampling technique to select…

Purpose: The purpose of this paper is to describe some of the problems and issues faced by online library catalogues. It aims to establish how libraries have undertaken the mission of developing the next generation catalogues and how they compare to new tools such as Amazon. Design/methodology/approach: An expert study was carried out in January…

The 13th iteration of the International Conference on Educational Data Mining (EDM 2020) was originally arranged to take place in Ifrane, Morocco. Due to the SARS-CoV-2 (coronavirus) epidemic, EDM 2020, as well as most other academic conferences in 2020, had to be changed to a purely online format. To facilitate efficient transmission of…

The Third International Conference on Data Mining (EDM 2010) was held in Pittsburgh, PA, USA. It follows the second conference at the University of Cordoba, Spain, on July 1-3, 2009 and the first edition of the conference held in Montreal in 2008, and a series of workshops within the AAAI, AIED, EC-TEL, ICALT, ITS, and UM conferences. EDM 2011…

Purpose: The automatic removal of suffixes from words in English is of particular interest in the field of information retrieval. This work was originally published in Program in 1980 and is republished as part of a series of articles commemorating the 40th anniversary of the journal. Design/methodology/approach: An algorithm for suffix stripping…

Recently considerable attention has been given in the online information retrieval literature to techniques for producing a weighted output of documents in response to a request. One approach tries to maintain the form of and relationships among requests as they appear in current Boolean logic-based systems, while extending it to permit a weighted…

The single-link cluster method is used to construct a hierarchic classification for the 1400 documents in the Cranfield test collection. A variety of retrieval strategies applied to this hierarchy are evaluated in terms of effectiveness and efficiency. (Author)

The mathematical theory of measurement is used to construct a framework for the evaluation of information retrieval strategies. (Author)

Reports the results of experiments in document clustering using three well-known test collections. (Author)

This report evaluates the engineering information services provided by the University of Calgary since implementation of the COMPENDEX (tape service of Engineering Index, Inc.) service using the IBM TEXT-PAC system. Evaluation was made by a survey of the users of the Current Information Selection (CIS) service, the interaction between the system…

Some extensions of the methodology of document retrieval system evaluation are presented in this report. Part I provides an overview of some of the milepost studies in evaluation. Part II presents in some detail a discussion of measurement from a nonconventional viewpoint, including such topics as why measure at all, what measures are appropriate…

A relational document retrieval system is developed that is primarily concerned with hierarchic tree structures and lateral links. The lateral linkages are relationships that cannot be represented within the tree structure representation. A number of annotated examples are given along with a detailed description of the relational data structure…

Five abstracts journals and one indexing service in the field of library and information science were compared for the efficacy of their subject retrieval performance. (Author)

Describes the concept of maximum indexing, a system aimed at achieving maximum recall and maximum precision in computerized information retrieval. The indexing strategies used to achieve maximum indexing and the problems that arise are discussed. (9 references) (CLB)

Introduces a new model of viewing documents based on citing-cited relationship between them. Using Bayes' decision theory, it is shown how source document may be indexed and weighted by relevant cited document features, corresponding to one pass relevance feedback Model 1 (probabilistic indexing) or Model 2 (probabilistic retrieval).
