An Information Processing Constraints Approach to the Conjunction of Macroeconomic and Macropolitical Theory
Peer reviewed Peer reviewed
McAlpine, W. E. – Information Processing and Management, 1976
A generalized Keynesian "general equilibrium" model, derived largely from macropolitical considerations, is presented. (Author)

Experimental and Quasi-Experimental Designs for Research in Information Science.
Peer reviewed Peer reviewed
Haas, David F.; Kraft, Donald H. – Information Processing and Management, 1984
This paper examines representative research in information science and compares its designs to an abstract ideal of the experimental research design. Threats to validity of conclusions are highlighted, including history, maturation, testing, instrumentation, statistical regression, selection biases, experimental mortality, and selection-maturation…

Ranking Techniques and the Empirical Log Law.
Peer reviewed Peer reviewed
Brookes, Bertram C. – Information Processing and Management, 1984
Four empirical laws of bibliometrics--anomalous number, Lotka's, Zipf's, and Bradford's--together with Laplace's "law of succession" and de Solla Price's cumulative advantage distribution are shown to be almost identical. A simple model shows that the frequency forms conform with inverse square law over appropriate interval. (Fifteen…

Information Science: The Study of Postmodern Knowledge Usage.
Peer reviewed Peer reviewed
Wersig, Gernot – Information Processing and Management, 1993
Proposes that information science is a postmodern science, driven by the need to solve problems caused by classical sciences and technologies. Some basic structures of current approaches to information science, the role of knowledge, information as knowledge for action, and the theoretical structures needed to establish the bases of information…

User Models and World Models for Data, Information, and Knowledge.
Peer reviewed Peer reviewed
Teskey, F. N. – Information Processing and Management, 1989
Presents a model that distinguishes between data as directly observable facts, information as structured collections of data, and knowledge as methods of using information. The discussion covers the likely benefits of the use of the model for a semantic information retrieval system using the concept of semantic categories. (28 references)…

A Learning Scheme for Information Retrieval in Hypertext.
Peer reviewed Peer reviewed
Savoy, Jacques – Information Processing and Management, 1994
Proposes a new learning algorithm to improve the retrieval effectiveness of the search system used in the hypertext environment using an extended Boolean model with links to improve the ranking of retrieved items. Highlights include the basic retrieval scheme, the learning scheme, and a review of basic probabilistic retrieval models. (Contains 32…

The Dual Approach to the Value of Information: An Appraisal of Use and Exchange Values.
Peer reviewed Peer reviewed
Repo, Aatto J. – Information Processing and Management, 1986
Develops a framework for analyzing the value of information, information products, and services from the viewpoint of information use, and analyzes the practical values of different types of information to study the problems involved in assessing their value-in-use and exchange value. Existing research studies are analyzed using this approach.…
