Computer-based generation of natural language requires consideration of two different types of problems: i) determining the content and textual shape of what is to be said, and 2) transforming that message into English. A computational solution to the problems of deciding what to say and how to organize it effectively is proposed that relies on an interaction between structural and semantic processes. Schemas, which encode aspects of discourse structure, are used to guide the generation process. A focusing mechanism monitors the use of t h e schemas, providing constraints on what can be said at any point. . | TOE TEXT SYSTEM FOR NATURAL LANGUAGE GENERATION AN OVERVIEW Kathleen R. McKeown Dept of Computer Information Science The Moore School University of Pennsylvania Philadelphia Pa. 19104 ABSTRACT Computer-based generation of natural language requires consideration of two different types of problems 1 determining the content and textual shape of what is to be said and 2 transforming that message into English. A computational solution to the problems of deciding what to say and how to organize it effectively is proposed that relies on an interaction between structural and semantic processes. Schemas which encode aspects of discourse structure are used to guide the generation process. A focusing mechanism monitors the use of the schemas providing constraints on what can be said at any point. These mechanisms have been implemented as part of a generation method within the context of a natural language database system addressing the specific problem of responding to questions about database structure. INTRODUCTION Deciding what to say and how to organize it effectively are two issues of particular importance to the generation of natural language text. In the past researchers have concentrated on local issues concerning the syntactic and lexical choices involved in transforming a pre-determined message into natural language. The research described here emphasizes a computational solution to the more global problems of determining the content and textual shape of what is to be said. More specifically my goals have been the development and application of principles of discourse structure discourse coherency and relevancy criterion to the computer generation of text. These principles have been realized in the TEXT system reported on in this paper. The main features of the generation method used in TEXT include 1 an ability to select relevant information 2 a system for pairing rhetorical techniques such as analogy with discourse purposes such as defining terms and 3 a .
