A document generation system which employs a definition-based expert system and an editor to produce an output document from a template document and expert system responses. The knowledge base of the expert system consists of a hierarchy of terms and their definitions. To produce an expert response, an inference engine component of the expert system evaluates a term by evaluating all of the definitions for the terms which are in that term's hierarchy of definitions. In the document generation system, the terms include fragment terms which are defined as portions of the template document. Other terms of the knowledge base may appear within the portion. The document generation system includes a term definition component which, when the user defines a fragment term, provides the editor to the user so that the user can write the fragment represented by the fragment term. After the user has defined the fragment term, the term definition component adds the fragment term to the knowledge base and verifies that any other terms in the portion are defined in the knowledge base. If they are not, the user is asked for a definition. To produce a document, the inference engine evaluates a term which is defined in terms of one or more fragment terms. When the evaluation indicates that a fragment term is to be included in the document, the inference engine uses the editor to retrieve any other terms in the fragment, evaluates the other terms, and then uses the editor to copy the fragment term's text from the template document to the document being produced and to replace the other terms in the document being produced with their values.
