# Why natural language as an interface medium?

- Simple formulation of complex queries:
  The formulation of complex queries is easier, faster, and more precise in natural language than in formal retrieval languages.
- Humane access to computers:
  The machine serves the user, not vice versa.
- Democratic access to information:
  Information access does not require special skills.
