A considerable body of accumulated knowledge about the design of languages for communicating information to computers has been derived from the subfields of programming language design and semantics. It has been the goal of the P A r R group at SRI to utilize a relevant portion of this knowledge in implementing tools to facilitate communication of linguistic information to computers. The PATR-II formalism is our current computer language for encoding linguistic information. | The Design of a Computer Language for Linguistic Information Stuart M. Shieber Artificial Intelligence Center SRI International and Center for the Study of Language and Information Stanford University Abstract A considerable body of accumulated knowledge about the design of languages for communicating information to computers has been derived from the subfields of programming language design and semantics. It has been the goal of the PATR group at SRI to utilize a relevant portion of this knowledge in implementing tools to facilitate communication of linguistic information to computers. The PATR-n formalism is our current computer language for encoding linguistic information. This paper a brief overview of that formalism attempts to explicate our design decisions in terms of a set of properties that effective computer lan guages should incorporate. 1. Introduction1 The goal of natural-language processing research can be stated quite simply to endow computers with human language capability. The pursuit of this objective however has been a difficult task for at least two reasons first this capability is far from being a well-understood phenomenon second the tools for teaching computers what we do know about human language are still very primitive. The solution of these problems lies within the respective domains of linguistics and computer science. Similar problems have arisen previously in computer science. Whenever a new computer application area emerges there follow new modes of communication with computers that are geared towards such areas. Computer languages are a direct result of this need for effective communication with computers. A considerable body of accumulated knowledge about the design of languages for communicating information to computers has been derived from the subfields of programming language design and seman- This research has been made possible in part by a gift from the Systems Development Foundation and was also supported by the Defense .
