Relation Extraction

Relation Extraction identifies relationships between entities in text — "Apple acquired Beats Electronics in 2014" yields the relation (Apple, acquired, Beats Electronics, 2014). The technique is foundational to knowledge graph construction, document understanding, regulatory analysis, and structured information retrieval. Real-world applications include extracting drug-drug interactions from medical literature, identifying corporate mergers and acquisitions from news, mapping organizational hierarchies from filings, building product-to-feature relationships from reviews, and constructing financial entity graphs from earnings reports. Classical approaches used hand-crafted features and supervised classifiers; modern approaches use transformer models like REBEL (Relation Extraction By End-to-end Language generation) or simply LLM prompting ("extract all subject-verb-object relations from this paragraph as JSON"). Tools include spaCy with custom components, Hugging Face transformers, and the structured-output features of modern LLM APIs. AI governance, AI compliance, and AI risk management programs use relation extraction to build evidence of regulatory relationships and compliance obligations across enterprise AI environments.
