You can perform keyword-based queries to knowledge stored within EpiK, the Episodic Logic Knowledge Base, produced by Knext. To learn more about Knext and Episodic Logic, see the Knext homepage.

Search Tips

  • Use verbs in base form (‘fight’), not conjugated or past tense (‘fighting’, ‘fought’).
  • Specific individuals are abstracted to kinds, so search for ‘philosopher’, not ‘Descartes’.

 

  • You can constrain your search with a part-of-speech tag: ‘bank.v’ will return fewer results than ‘bank’.
  • You can search for multiple terms, e.g., ‘house cat’ to get only results that contain both words.
