Rule-based computations on English
Robert F. Simmons · ACM SIGART Bulletin · 1977
A linear notation for expressing semantic networks as sets of semantic predicates is outlined. Rule forms are presented for translating from English discourse to semantic predicates. Rules for generating English sentences and for computing causal chains from semantic predicates are described. Each of these rule forms has been tested in an existing question answering system. A brief analysis of rule-based systems is given and a method for designing them is suggested.
