Named entities and information extraction

Pull names, places and facts out of text.

📖 Key ideas

  1. NER finds entities: person, organisation, location, date, money.
  2. Part-of-speech tagging labels nouns, verbs, etc.
  3. Dependency parsing finds grammatical relationships.
  4. Relation extraction links entities (Sundar Pichai → CEO of Google).
  5. spaCy provides ready NER models.
💡 Real-life example: NER is a highlighter marking names in blue, places in green and dates in yellow.
