Designing and Implementing Discriminants for LFG Grammars

We extend discriminant-based disambiguation techniques to LFG grammars. We present the design and implementation of lexical, morphological, c-structure and f-structure discriminants for an LFG-based parser. Chief considerations in the computation of discriminants are capturing all distinctions between analyses and relating linguistic properties to words in the string. Our work is mostly tested on Norwegian, but our approach is independent of the language and grammar.
