 Knowledge‐assisted document retrieval: II. The retrieval processGautam Biswas, James C. Bezdek, Viswanath Subramanian and Marisol Marques Journal of the American Society for Information Science, 1987, vol. 38, issue 2, 97-110 Abstract: This article presents our conceptual model of the retrieval process of a document‐retrieval system. The retrieval mechanism input is an unambiguous intermediate form of a user query generated by the language processor using the method described previously. Our retrieval mechanism uses a two‐step procedure. In the first step a list of documents pertinent to the query are obtained from the document database, and then an evidence‐combination scheme is used to compute the degree of support between the query and individual documents. The second step uses a ranking procedure to obtain a final degree of support for each document chosen, as a function of individual degrees of support associated with one or more parts of the query. The end result is a set of document citations presented to the user in ranked order in response to the information request. Numerical examples are given to illustrate various facets of the overall system, which has been prototypically implemented in modular form to test system response to changes in model parameters. © 1987 John Wiley & Sons, Inc.
