WOODS Department of Cocputer Science Virginia Technological University ABSTRACT Augmented Transition Network gran-mars have significant areas of unexplored application as a simulation tool for granmar designers. The intent of this paper is to discuss some current efforts in developing a granmar testing tool for the specialist in linguistics. The scope of the system under discussion is to display structures based on the modeled granular. Full language definition with facilitation of semantic interpretation is not within the scope of the systems described in this paper. Application of granmar testing to an applied linguistics research environment is emphasized. Extensions to the teaching of linguistics principles and to refinement of the primitive ẴTK functions are also considered. 1. Using Network Ifodels in Experimental Granular Design Application of the ATN to general granmar modeling for sinulation and cooperative purposes was first suggested by cfoods l . Motivating factors for using the network model as an applied grammar design tool are 1. The model provides a means of organizing structural descriptions at any level from surface syntax to deep propositional interpretations. 2. A network model may be used to represent different theoretical approaches to gramnar definition. 3. The graphical representation of a granmar permitted by the network model is a relatively clear and precise way to express notions about structure. 4. Computational simulation of the granmar enables systematic tracing of subconpcnents and testing against text data. Grimes 2 in a series of linguistics workshops demonstrated the utility of the network model even in environments where computational testing of granmars was not possible. Grimes along with other contributors to the referenced work illustrated the flexibility of the AIN in ragpemlc analysis of granmatỉcal
