A Logical Framework for the Correction of Spelling Errors in Electronic Documents.
Peer reviewed Peer reviewed
Berghel, H. L. – Information Processing and Management, 1987
Proposes a method for correcting spelling errors found in electronic documents which is derived from a logical analysis of the problem. Similarity relations and character string matching are discussed, the use of PROLOG is described, suggestions for further research are made, and a literature review is included.

Use of a Virtual Information System for Bibliometric Analysis.
Peer reviewed Peer reviewed
Burton, Hilary D. – Information Processing and Management, 1988
Defines and discusses bibliometrics, particularly as carried out in automated systems. The specific requirements to which data should conform to support bibliometric analysis are detailed and explained, and the Intelligent Gateway of the Lawrence Livermore National Laboratory is described.

Using Bitmaps for Medium Sized Information Retrieval Systems.
Peer reviewed Peer reviewed
Bookstein, A.; Klein, S. T. – Information Processing and Management, 1990
Describes the theoretical framework of a retrieval system that uses data structures called bitmaps to improve search algorithms for medium-sized systems. Information retrieval systems that contain the full text of the documents are discussed, and the use of inverted files such as concordances for small texts is explained. (24 references) (LRW)

A Comparative Study of Multiple Attribute Tree and Inverted File Structures for Large Bibliographic Files.
Peer reviewed Peer reviewed
Nageswara Rao, S. V.; And Others – Information Processing and Management, 1985
Discusses properties of multiple attribute tree (MAT) and inverted file structures; establishes suitability of MAT data structure for bibliographic files using worst-case performance measures; provides arguments to establish MAT average case superiority; and proposes an efficient adaptation of MAT data structure to exploit special features of MAT…

Measurement of Information.
Peer reviewed Peer reviewed
Hayes, Robert M. – Information Processing and Management, 1993
Presents and discusses implications of a set of measures of information. Definitions of relevant terms, including fact, data, representation, information, and knowledge, are given; four levels of processing data are explained (i.e., data transfer, data selection, data analysis, and data reduction); and relationships between information and…

Outlines of the Emerging Paradigm in Cataloguing.
Peer reviewed Peer reviewed
Davies, Roy – Information Processing and Management, 1987
Discusses possibility of using expert systems to develop new model in cataloging theory made necessary by technological progress, rising user expectations, and economic pressures. A data structure for bibliographic information required by Anglo American Cataloging Rules, 2nd edition, (AACR2) is suggested, and possible heuristics for interpreting…

A Hyperknowledge Framework of Decision Support Systems.
Peer reviewed Peer reviewed
Chang, Ai-Mei; And Others – Information Processing and Management, 1994
Presents a hyperknowledge framework of decision support systems (DSS). This framework formalizes specifics about system functionality, representation of knowledge, navigation of the knowledge system, and user-interface traits as elements of a DSS environment that conforms closely to human cognitive processes in decision making. (Contains 52…
