In this paper we illustrate and underline the importance of making detailed linguis- tic information a central part of the pro- cess of automatic acquisition of large-scale lexicons as a means for enhancing robust- ness and at the same time ensuring main- tainability and re-usability of deep lexi- calised grammars. Using the error mining techniques proposed in (van Noord, 2004) we show very convincingly that the main hindrance to portability of deep lexicalised grammars to domains other than the ones originally developed in, as well as to ro- bustness of systems using such grammars is low lexical coverage. To this effect, we develop linguistically-driven methods that use detailed morphosyntactic informa- tion to automatically enhance the perfor- mance of deep lexicalised grammars main- tai...
