The knowledge representation is an important factor in natural language generation since it limits the semantic capabilities of the generation system. This paper identifies several information types in a knowledge representation that can be used to generate meaningful responses to questions about database structure. Creating such a knowledge representation, however, is a long and tedious process. A system is presented which uses the contents of the database to form part of this knowledge representation automatically. . | AUGMENTING A DATABASE KNOWLEDGE REPRESENTATION FOR NATURAL LANGUAGE GENERATION Kathleen F. McCoy Dept of Computer and Information Science The Moore School University of Pennsylvania Philadelphia Pa. 19104 ABSTRACT The knowledge representation is an important factor in natural language generation since it limits the semantic capabilities of the generation system. This paper identifies several information types in a knowledge representation that can be used to generate meaningful responses to questions about database structure. Creating such a knowledge representation however is a long and tedious process. A system is presented which uses the contents of the database to form part of this knowledge representation automatically. It employs three types of world knowledge axioms to ensure that the representation formed is meaningful and contains salient information. representation reflects both the database contents and the database designer s view of the world. One important class of questions involves canparing database entities. Hie system s knowledge representation must therefore contain meaningful information that can be used to make comparisons analogies between various entity classes. Ulis paper focuses specifically on those aspects of the knowledge representation generated by ENHANCE which facilitate the use of analogies. An overview of the knowledge representation used by TEXT is first given. This is followed by a discussion of how part of this representation is automatically created by ENHANCE. INTRODUCTION In order for a user to extract meaningful information from a database system s he must first understand the system s view of the world what information the system contains and what that information represents. An optimal way of acquiring this knowledge is to interact in natural language with the system itself posing questions to it about the structure of its contents. The TEXT system McKeown 82 was developed to facilitate this type of interaction. In .
