Abstract : The report describes research which has been done toward developing a system for performing simulation analyses through natural language interaction with a computer. A general system for natural language processing, consisting of an IBM 360 FORTRAN program and a 'rule language', has been developed. The user of this system must write sets of 'decoding' and 'encoding' rules, along with some declarations, to specify how processing is to be done for his application. Decoding rules specify how text is to be processed to produce an entity-attribute-value data structure, and encoding rules specify how text is to be produced from such a data structure. The FORTRAN program does the processing according to the sets of rules it is given. Several sets of decoding and encoding rules have been written to implement a specific system which is capable of carrying on a dialogue in English about a simple queuing problem and then producing a program in the GPSS language to do the simulation.
