Coreference Resolution

Coreference Resolution identifies when different expressions in text refer to the same entity — "Apple announced new products this week. The company unveiled iPhone 17 and Vision Pro 2. Tim Cook said he was excited about both." Coreference resolution links "Apple," "The company," and "Tim Cook... he" appropriately. The task is fundamental to deep text understanding and underpins many downstream applications: question answering, summarization, knowledge-graph extraction, and document understanding. Classical approaches used hand-crafted features and statistical models; modern approaches use transformer-based models like SpanBERT, CorefQA, and increasingly LLM prompting. Real-world applications include resolving "the patient" references throughout a clinical note, tracking parties through a legal contract, identifying who said what in meeting transcripts, and connecting customer mentions across long support threads. Tools include AllenNLP, Hugging Face transformers, spaCy's coreference extensions, and Stanford CoreNLP. AI governance, AI compliance, and AI risk management programs benefit from coreference resolution because it enables accurate entity-level tracking across documents — supporting responsible AI in any enterprise AI text-understanding pipeline.
