Reuse of plan-based knowledge sources in a uniform TAG-based generation system
Karin Harbusch, Jens Woch · 2000
In a uniform generation system all knowledge bases are specied in the same formalism and run the same processing component. The advantage of this behavior is that any order of applying the knowledge bases, i.e. a negotiation on revisions between the individual components, can easily be imposed on the system. Furthermore, the implementation of the overall system is simpler because only one algorithm must be developed and tested. In the project InTeGenInE we specify all knowledge sources in the formalism of SchemaTree Adjoining Grammars with Unication (SUTAGs). A general paradigm of our work is to reuse existing knowledge bases, i.e. to transform various formats into a SUTAG. For the syntactic and lexical knowledge the existing XTAG system has already automatically been transformed. In this paper we address the general question how to transform planbased knowledgesources which are frequently used in the whattosay part of a generation system. As an instance of the general trans...
