Entity Linking

Entity Linking resolves mentions in text to specific records in a knowledge base — distinguishing whether "Apple" refers to the technology company, the fruit, or the record label. Entity linking systems combine named-entity recognition with disambiguation against a reference database (Wikipedia, Wikidata, an internal product catalog, a customer master, or a knowledge graph). The technique is essential for knowledge graph construction, semantic search, content recommendation, and question-answering systems. Famous research systems include DBpedia Spotlight, Babelfy, REL, and various LLM-based entity linkers. Modern enterprise systems link mentions to internal master data — connecting customer mentions in emails to CRM records, product mentions in social media to a product catalog, or supplier mentions in invoices to a procurement system. AI governance, AI compliance, and AI risk management programs use entity linking to build authoritative relationships across enterprise data — supporting responsible AI through traceable, canonical references across enterprise AI portfolios at scale.
