Traditional approaches to natural language processing (NLP) can be considered construction-based. That is to say, they employ surface oriented, language specific rules, whether in the form of an Augmented Transition Network (ATN), logic grammar or some other grammar/parsing formalism. The problems of such approaches have always been apparent; they involve large sets of rules, often ad hoc, and their adequacy with respect to the grammar of the language is difficult to ensure.
