Struct EntityFeatureExtractor 

pub struct EntityFeatureExtractor { /* private fields */ }

Entity feature extractor.

Extracts comprehensive features from entities at multiple levels:

• Mention context (surrounding text, position)
• Chain aggregates (for coreference chains)
• Co-occurrence patterns (which entities appear together)

Extract only chain features (requires grouping).

pub fn extract_cooccurrence( &self, entities: &[Entity], ) -> HashMap<String, CooccurrenceFeatures>
