Information Retrieval: Easy English, a language for information retrieval through a remote typewriter console

Easy English is a natural command language designed to simplify communication between man and machine through remote typewriter console. It has been developed for retrieval of documents from a computerized data base, the Moore School Information Systems Laboratory files. Requests are formulated in a standardized syntactical form (examples of which are presented), and this form is then transformed into an equivalent query expressed in the retrieval system's original Symbolic Command Language, which is briefly described. Operation of Easy English is detailed by illustration of the transformations performed upon a sample request up to the point at which the request string is sent to the system.
