In Biblical Hebrew verb semantics, one of the challenges is to understand how referents are associated with the predicate as bound or free entities and how this determines the nature of the event expressed in a particular language use. Without an understanding of this relational aspect of clause structure, it is neither possible to build a Hebrew lexicon, nor, in particular, to explain the function of verbal valency patterns and exploit them for learning purposes. Role and Reference Grammar is a theory which assumes that event structure can best be explained by verb-specific roles. Classes of verbs are characterized by characteristic configurations of actors and undergoers in typical groupings. This allows the linguist to map from syntax to semantics through a lexicon which stores the logical structure of the predicates. The meaning of a verb is described in semantic representations which takes the characteristic role configuration into account. This paper will describe a database application called the Role Lexical Module which has been built for verb classification from the Werkgroep Informatica database at the Vrije Universiteit (http://lex.qwirx.com/lex/clause.jsp). It will describe the flow chart for lexical decomposition used in this application and then suggest how this could be turned into an account which would be teachable in introductory grammar and which could be programmed into a simple tool for language learning. The research behind this paper is part of combining the EuroPLOT EU project with the Dutch NOW project (http://www.eplot.eu/project-definition/workpackage-5)
