Systemic grammar has been used for AI text generation work in the past, but the Implementations have tended be ad hoc or inefficient. This paper presents an approach to systemic text generation where AI problem solving techniques are applied directly to an unadulterated systemic grammar. This approach is made possible by a special relationship between systemic grammar and problem solving: both are organized primarily as choosing from alternatives. The result is simple, efficient text generation firmly based in a linguistic theory. . | A PROBLEM SOLVING APPROACH TO GENERATING TEXT FROM SYSTEMIC GRAMMARS Terry Patten Dent of Artificial Intelligence University of Edinburgh Hope Park Square Meadow Lane EH8 9NW. ABSTRACT Systemic grammar has been used for Al text generation work In the oast but the implementations have tended be ad hoc or inefficient. This paper oresents an approach to systemic text generation where Al problem solving techniques are applied directly to an unadulterated systemic grammar. This approach.is made possible by a special relationship between systemic grammar and problem solving both are organized primarily as choosing from alternatives. The result is simple efficient text generation firmly based In a linguistic theory. INTRODUCTION This paper will describe an approach to text generation where Al problem solving techniques are used to generate text from systemic grammars. Problem solving 13 a general term used here to refer to areas of Al research such as expert systems planning design and so on Hayes-Roth et al. 1983 J. Techniques developed In these fields are applied directly to an unadulterated systemic grammar resulting in a simple efficient text generator firmly based in an established linguistic theory. This approach is only possible because of a fundamental relationship that exists between systemic grammar and Al problem solving. This relationship is described in the next section. The third section will be concerned with one of the most important manifestations of this special relationship a common representation. The following section will show how this common representation allows goal directed problem solving techniques to be applied directly to the grammar. One of the most novel and Important aspects of this approach is that it is compatible with the semantic stratum described in the systemic theory a system network organized around the idea of register Halliday 1978J. The semantic stratum and its relationship to the grammar will be discussed next. Some advantages
