Adding Knowledge to a Graph

Now that we have a graph created, let's populate it with knowledge by generating triples from unstructured text. The generate_triples method extracts structured subject-predicate-object relationships and disambiguate automatically.

[36]

📝 Input Text:
Albert Einstein developed the theory of general relativity in 1915.
He was born in Ulm, Germany, and later became a Swiss citizen.
Einstein received the Nobel Prize in Physics in 1921 for his explanation
of the photoelectric effect. He worked at the Institute for Advanced Study
in Princeton, New Jersey.

🔗 Generated Triples:
------------------------------------------------------------
  Albert Einstein → developed → general relativity
  Albert Einstein → developed → the theory of general relativity
  Albert Einstein → published → the general theory of relativity in 1915
  Albert Einstein → born_on → 14 March 1879
  Albert Einstein → born_in → Ulm
  Ulm → located_in → Germany
  Albert Einstein → became_citizen_of → Switzerland
  Albert Einstein → became_Swiss_citizen_in → 1901
  Albert Einstein → received → the Nobel Prize in Physics (1921)
  Albert Einstein → received_Nobel_Prize_in_Physics_for → his discovery of the law of the photoelectric effect
  Albert Einstein → served_as_faculty_member_at → Institute for Advanced Study

Working with Entities

Entities are the subjects and objects in your knowledge graph. You can manage them directly.
