The implementation of the CLS constructor in ARTEMIS
Most natural language processing researchers highlight the benefits of interlingua-based systems in multilingual settings. In this scenario, Role and Reference Grammar can contribute to build a cross-language semantic representation of the input text in terms of its logical structure. Our goal is to describe the various stages in the development of one of the first computational systems which employs a lexico-conceptual knowledge base to generate the logical structure of sentences. Our approach actually involved some changes in the standard functional model in order to convert the logical structure into an ontology-grounded representation of sentential meaning. In fact, we demonstrate that constructional schemata should become the cornerstone of the syntax-semantics interface in this computerized model of Role and Reference Grammar.
