Adaptive Man-Machine Interaction in Information Retrieval; A Dissertation in Electrical Engineering.
Edwards, John S. – 1967
Three specific contributions to the field of information retrieval are presented. The first two describe the establishment of an adaptive, interactive man-machine dialogue that produces a form of unsolicited librarian-like assistance for the user in his selection of index terms to characterize an indexing function. The data set upon which the…
