Ontology-based semantic interpretation as grammar rule constraints

Abstract

We present an ontology-based semantic interpreter that can be linked to a grammar through grammar rule constraints, providing access to meaning during parsing and generation. In this approach, the parser will take as input natural language utterances and will produce ontology-based semantic representations. We rely on a recently developed constraint-based grammar formalism, which balances expressiveness with practical learnability results.We show that even with a weak "ontological model", the semantic interpreter at the grammar rule level can help remove erroneous parses obtained when we do not have access to meaning. © Springer-Verlag 2010.
