Three-place predicates in RRG
This book chapter presents a computational linguistics analysis of Role and Reference Grammar [RRG] (cf. Van Valin 2005). RRG, formulated as a pseudo-code program is not executable on a random access machine since the linking algorithm cannot account for variable undergoer linking in English three-place predicates. Consequently RRG is not computationally adequate. Therefore a new approach to RRG is developed using Nolan’s (2011) constructional schemas; the RRG semantics-to-syntax linking algorithm is revised, using the lexicon, information structure and constructional schemas to account for variable undergoer linking. A revised approach to the mental lexicon based on Gottschalk (2010) is developed, accounting for three-place predicates. In this approach macroroles are epiphenomenal and replaced by thematic relations to develop a computable account to RRG.
