Struct EventExtractor 

pub struct EventExtractor { /* private fields */ }

Event extractor with optional neural backend.

Rule-based (default): Uses ACE 2005 trigger lexicon for fast extraction. Neural (with candle feature): Uses GLiNER bi-encoder for zero-shot extraction.

The neural backend is preferred when available as it generalizes better to unseen event types and handles ambiguity.

Implementations

impl EventExtractor

pub fn new() -> EventExtractor

Create a new event extractor with default lexicon (rule-based only).

pub fn with_config( config: EventExtractorConfig, ) -> Result<EventExtractor, Error>

Create with custom configuration.

If config.gliner_model is set and candle feature is enabled, will attempt to load the GLiNER model for neural extraction.

pub fn with_gliner(model_id: &str) -> Result<EventExtractor, Error>

Create with GLiNER model for neural extraction.

pub fn has_neural_backend(&self) -> bool

Check if neural extraction is available.

pub fn extract(&self, text: &str) -> Vec<EventMention>

Extract events from text.

Uses GLiNER (neural) if available, otherwise falls back to rule-based extraction.

pub fn extract_referents(&self, text: &str) -> Vec<DiscourseReferent>

Extract events and convert to discourse referents.

pub fn extract_with_entities( &self, text: &str, entities: &[Entity], ) -> Vec<EventMention>

Extract events with entity context (for argument filling).

When entities are provided, they OVERRIDE heuristic argument extraction since NER entities are more reliable than capitalization heuristics.

pub fn lexicon(&self) -> &EventTriggerLexicon

Get the lexicon for inspection or modification.

Trait Implementations
