The IDAS natural-language generation system uses a KL-ONE type classifier to perform content determination, surface realisation, and part of text planning. Generation-by-classification allows IDAS to use a single representation and reasoning component for both domain and linguistic knowledge, which is difficult for systems based on unification or systemic generation techniques. | USING CLASSIFICATION TO GENERATE TEXT Ehud Reiter and Chris Mellisht Department of Artificial Intelligence University of Edinburgh 80 South Bridge Edinburgh EH1 1HN BRITAIN ABSTRACT The IDAS natural-language generation system uses a KL-ONE type classifier to perform content determination surface realisation and part of text planning. Generation-by-classification allows IDAS to use a single representation and reasoning component for both domain and linguistic knowledge which is difficult for systems based on unification or systemic generation techniques. Introduction Classification is the name for the procedure of automatically inserting new classes into the correct position in a KL-ONE type class taxonomy Brachman and Schmolze 1985 . When combined with an attribute inheritance system classification provides a general pattern-matching and unification capability that can be used to do much of the processing needed by NL generation systems including content-determination surfacerealisation and portions of text planning. Classification and inheritance are used in this manner by the IDAS natural language generation system Reiter et al. 1992 and their use has allowed IDAS to use a single knowledge representation system for both linguistic and domain knowledge. IDAS and II IDAS IDAS is a natural-language generation system that generates on-line documentation and help messages for users of complex equipment. It supports user-tailoring and has a hypertext-like interface that allows users to pose follow-up questions. The input to IDAS is a point in question space which specifies a basic question type .
