  • On the grammar-based side, [[1992_SurfaceGramAnForTheExtrOfTermNPs|Bourigault (1992)]] describes a system for extracting “terminological noun phrases” from French text. This system first uses heuristics to find “maximal length noun phrases", and then uses a grammar to extract “terminological units." For example, from the maximal NP le disque dur de la station de travail it extracts the two terminological phrases disque dur, and station de travail. Bourigault claims that the grammar can parse "around 95% of the maximal length noun phrases" in a test corpus into possible terminological phrases, which then require manual validation. However, because its goal is terminological phrases, it appears that this system ignores NP chunk-initial determiners and other initial prenominal modifiers, somewhat simplifying the parsing task.
