An Introduction to Genetic Algorithms and to Their Use in Information Retrieval.
Peer reviewed Peer reviewed
Jones, Gareth; And Others – Online & CD-ROM Review, 1994
Genetic algorithms, a class of nondeterministic algorithms in which the role of chance makes the precise nature of a solution impossible to guarantee, seem to be well suited to combinatorial-optimization problems in information retrieval. Provides an introduction to techniques and characteristics of genetic algorithms and illustrates their…

Web Mining: Machine Learning for Web Applications.
Peer reviewed Peer reviewed
Chen, Hsinchun; Chau, Michael – Annual Review of Information Science and Technology (ARIST), 2004
Presents an overview of machine learning research and reviews methods used for evaluating machine learning systems. Ways that machine-learning algorithms were used in traditional information retrieval systems in the "pre-Web" era are described, and the field of Web mining and how machine learning has been used in different Web mining…

Application of Loglinear Models to Informetric Phenomena.
Peer reviewed Peer reviewed
Bookstein, Abraham; And Others – Information Processing and Management, 1992
Describes the use of loglinear statistical models in the field of informetrics, especially for the analysis of information systems. A detailed example is given of developing a model based on loglinear analysis to determine book acquisition patterns in libraries, including mathematical considerations and algorithms.

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…

Coding for Recording and Recall of Information.
Peer reviewed Peer reviewed
Kochen, Manfred – Information Processing and Management, 1984
Explores potential of mathematical theory of communication for information science and examines question of how to encode a message at time it is encountered for subsequent recall. Examples of problem, a prototype computer program and experiment, coding as embedding in associational nets, and nature of information are discussed. (Nine references.)…

Proceedings of the Symposium on Information Storage and Retrieval...April 1-2, 1971.
Minker, Jack, Ed.; Rosenfeld, Sam, Ed. – 1971
The symposium focused on advances in techniques in the computer oriented technology of information retrieval. Early developments and the status of recent efforts in document retrieval, question answering and data management systems are briefly reviewed. Unless fundamental processing techniques are developed and made available to workers,…
