DATR is a lexical knowledge representation language developed by Roger Evans and Gerald Gazdar [...]. The language provides a notation for expressing generalizations about lexical items, and for allowing these generalizations to apply to specific lexical items by means of default inheritance. Evans and Gazdar have also implemented a computer programm capable of deriving relevant inferences from any hierarchically structured DATR lexicon.
