An Evaluation of Goffman's Indirect Retrieval Method
Peer reviewed Peer reviewed
Croft, W. B.; Van Rijsbergen, C. J. – Information Processing and Management, 1976
The indirect retrieval method proposed by Goffman is outlined and some similarities to other retrieval methods are indicated. The method is then evaluated and the results are compared with those obtained on the same document collection with cluster-based retrieval using single-link clustering. (Author)

Information Retrieval by Constrained Spreading Activation in Semantic Networks.
Peer reviewed Peer reviewed
Cohen, Paul R.; Kjeldsen, Rick – Information Processing and Management, 1987
Describes GRANT, an expert system for finding sources of funding given research proposals. The architecture of GRANT and the implementation of constrained spreading activation (a modified search algorithm based on semantic memory) are described, and recall and precision rates are analyzed.
