Feature cooccurrence restrictions (de)

Feature cooccurrence restrictions (FCRs) formulate well-formedness conditions for feature structures used by Generalized Phrase Structure Grammar. As a feature structure in this approach is taken to be an arbitrary set of feature specifications, it is necessary to block the combination of feature specifications which from a linguistic point of view make no sense. Most FCRs are formulated as implications.

Beispiel

Nur in verbalen Kategorien können das Merkmal vform enthalten: [VFORM] <math>\rightarrow</math> [+V, -N]

Phrasale Katgorien dürfen nicht das Merkmal subcat enthalten: [BAR 2] <math>\rightarrow</math> <math>\neg</math> [SUBCAT]

Kommentare

Moderne unifikationsbasierte Grammatikformalismen wie die Head-Driven Phrase Structure Grammar verwenden anstelle von FCRs typisierte Merkmalsstrukturen.
