pub struct EntityExtractor { /* private fields */ }Expand description
Rule-based entity extractor for dialogue systems.
Extracts dates, numbers, potential names (capitalised phrases), and location hints without relying on trained models.
Implementations§
Source§impl EntityExtractor
impl EntityExtractor
Sourcepub fn add_gazetteer_entry(&mut self, term: &str, kind: EntityKind)
pub fn add_gazetteer_entry(&mut self, term: &str, kind: EntityKind)
Add a custom gazetteer entry. Matching is case-insensitive.
Sourcepub fn extract(&self, utterance: &str) -> Vec<ExtractedEntity>
pub fn extract(&self, utterance: &str) -> Vec<ExtractedEntity>
Extract entities from utterance.
The extraction order is: gazetteer, dates, numbers, names (consecutive capitalised tokens), location hints. Overlapping spans are not deduplicated; callers should post-process if needed.
