A. | MEINONGIAN SEMANTICS FOR PROPOSITIONAL SEMANTIC NETWORKS William J.

ABSTRACT Tills paper surveys several approaches to semantic-network semantics that have not previously been treated in the Al or computational linguistics literature though there IS a large philosophical literature investigating them in some detail. In particular propositional semantic networks exemplified hv SXel S are dis cussed. It IS argued that only a lulls intensional Meinnngran semantics IS appropriate lor them and several Meinongian systems are presented. 1. SEMANTICS OF SEMANTIC NETWORKS. Semantic networks have proved to lie a uselul data structure lor representing information. . a knowledge representation svs tern. A better terminology is belief representation . Rapaport and Shapiro 1984. Rapaport 1981b I. The idea IS an old one Inheritance networks l ig. II. like those ol Quillian 1968. Fig. 1. An inheritance network. liohrow and Winograd s KRI. 1 177 . or Brachman s .I. 1979 . bear strong family resemblances to Torphvrv s Tree I II . 2 a mediaeval device used to illustrate the Aristotelian theory ol definition bv species and differentia cl. Kretzmann 196 . ll 2 Kneale and Kneale 1966 232 . It has been pointed out that there IS nothing essentially semantic about semantic networks Hendrix 1979 but cf. Woods 1975 Brachman 1979 . Indeed viewed as a data structure it is arguable that a semantic network IS a language possibly with an associated logic or inference mechanism for representing information about some dr main. and. as such. IS a purely syntactic entity. They have come to be called semantic primarily because of their uses as wavs of representing the mean ings of linguistic Items. As a notational device a semantic network can Itseil he given a semantics. That is. the arcs nodes and rules of a semantic network representational .
