Relation Extraction

Relation Extraction is a natural language processing (NLP) task that involves identifying and classifying semantic relationships between entities mentioned in unstructured text. It automatically extracts structured information about how entities (like people, organizations, or locations) are connected, such as 'works for', 'located in', or 'founded by'. This transforms raw text into machine-readable data for knowledge graphs, databases, or downstream applications.

Also known as: RE, Relationship Extraction, Semantic Relation Extraction, Entity Relation Extraction, Relation Mining
🧊Why learn Relation Extraction?

Developers should learn Relation Extraction when building systems that require understanding text beyond simple keyword matching, such as information retrieval, question answering, or knowledge base construction. It's essential for applications like automated news summarization, biomedical literature analysis (e.g., extracting drug-disease relationships), and enhancing search engines with semantic understanding, as it enables machines to grasp contextual connections in data.
