Making DATR work for speech: lexicon compilation in SUNDIAL
François Andry, Norman Fraser, Scott McGlashan, Simon Thornton, Nick Youd · 1992
We present dialex, an inheritance-based tool which facilitates the rapid construction of linguistic knowledge bases. Simple lexical entries are added to an application-specific datr lexicon which inherits morphosyntactic, syntactic, and lexico-semantic constraints from an applicationindependent set of structured base definitions. A lexicon generator expands the datr lexicon out into a disjunctive normal form lexicon. This is then encoded either as an acceptance lexicon (in which the constraining features are bit-encoded for use in pruning word lattices), or as a full lexicon (which is used for assigning interpretations, or for generating messages).
