A description of an experimental scheme for translating data retrieval requests, expressed in reasonable "natural" language, into a formalized format. The simple translation procedure, which immediately feeds its proposed translation back to the analyst, uses rules depending on the position of words in the request and simple semantic information about the class of words. It is programmed in a list processing language (IPL-V) and is oriented toward a relational file organization. The present scheme is designed to process a single request rather than a dialogue of requests and retrievals. Also, the translation procedure is not yet coupled to a retrieval process. 38 pp. Ref.
