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.
Example
Only verbal catgories can contain the feature vform: [VFORM] <math>\rightarrow</math> [+V, -N]
Phrasal catgories can not contain the feature subcat: [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.
