Information Retrieval System Design Issues in a Microcomputer-Based Relational DBMS Environment.
Wolfram, Dietmar – Microcomputers for Information Management, 1992
Outlines the file structure requirements for a microcomputer-based information retrieval system using FoxPro, a relational database management system (DBMS). Issues relating to the design and implementation of such systems are discussed, and two possible designs are examined in terms of space economy and practicality of implementation. (15…

Applying Informetric Characteristics of Databases to IR System File Design, Part I: Informetric Models.
Peer reviewed Peer reviewed
Wolfram, Dietmar – Information Processing and Management, 1992
Examines how informetric characteristics of information retrieval (IR) system databases can be used to help system designers decide what type of file structures would provide the best performance. The development of appropriate models describing database contents is highlighted in this first part of a two-part study. (30 references) (LRW)

Applying Informetric Characteristics of Databases to IR System File Design, Part II: Simulation Comparisons.
Peer reviewed Peer reviewed
Wolfram, Dietmar – Information Processing and Management, 1992
This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…

Traditional IR for Web Users: A Context for General Audience Digital Libraries.
Peer reviewed Peer reviewed
Wolfram, Dietmar; Xie, Hong (Iris) – Information Processing & Management, 2002
Discusses the emergence of general audience digital libraries (GADLs), a context that represents a hybrid of both traditional information retrieval, using primarily bibliographic resources provided by database vendors, and popular information retrieval such as public search systems on the Web. Reports findings of a study investigating end-user…

Preliminary Findings on Searcher Performance and Perceptions of Performance in a Hypertext Bibliographic Retrieval System.
Peer reviewed Peer reviewed
Wolfram, Dietmar; Dimitroff, Alexandra – Journal of the American Society for Information Science, 1997
Although hypertext system usage has been studied, little research has examined the relationship of searcher performance and perception of performance, particularly for hypertext-based information retrieval systems for bibliographic data. This article reports preliminary findings of a study at the University of Wisconsin-Milwaukee in which 83…

Hypertext vs Boolean-Based Searching in a Bibliographic Database Environment: A Direct Comparison of Searcher Performance.
Peer reviewed Peer reviewed
Wolfram, Dietmar; Dimitroff, Alexandra – Information Processing & Management, 1998
Describes a study that compared a hypertext-based bibliographic retrieval system with a traditional Boolean-based system. Results, conducted with novice and experienced searchers, revealed that the Boolean system performed better for tasks with a large number of relevant items, and that searcher experience level did not play a significant role.…
