The scope of coreference in conceptual graphs

Abstract

To modularize a large semantic net you need to show how the pieces relate to each other. Coreference allows concepts in two different graphs to refer to the same thing. This paper reviews the subject of coreference in the theory of conceptual graphs. 2 It explains basic concepts, gives current definitions, gives examples of different uses, and discusses some advanced applications, extending the application “scope” of coreference in the process.

The work reported on in this paper is based on two efforts. First, several discussion sessions on coreference were lead by the author at the University of Minnesota's Conceptual Graph Discussion Group organized by Professor Slagle. These were followed by extensive e-mail discussion among the Conceptual Graph community on most of the subjects described below. Many people contributed to those discussions and this paper is significantly better due to their participation. In short, this paper organizes and presents the results of those two efforts.
