Generalized DATR for flexible lexical access : PROLOG specification
Dafydd Gibbon · OpenGrey (Institut de l'Information Scientifique et Technique) · 1993
This report discusses criteria for a computational lexicon with flexible access strategies, and specifies a new generalised, constraint-oriented query language for DATR lexica (EDQL) which meets these requirements. A specification of EDQL semantics is given in Pure Prolog, and an implementation based on this specification, the Open DATR Engine (ODE), is described. The implementation is in Sicstus Prolog. The approach to integrated lexica is illustrated with a 'microlexicon' containing elementary semantic and surface lexical information. The ODE concept is intended as a general specification for spoken language lexicon acquisition and application research in the VERBMOBIL project (Work Packages 5.1 and 5.9); it is not a specification for the VERBMOBIL lexicon system.
