Disclaimer:
The institute's main page says: (we) "believe in the principle that
learning is key to successful NLP -- the same way that the language capabilities
of humans are based on learning". I don't believe this, and I doubt that we
know enough about learning of language capabilities in humans. As science is
not about believing, I prefer to develop algorithms, theorems and proofs.
