Ask HN: Is There a Platform for NLP (Natural Language Processing)?

I'd like to be able to use NLP as an API, however, not have my webapp do the heavy work, but rather feed it a bunch of data and be able to query that data via natural language.

For example, I could feed it a bunch of "Trips" or "People", and then query via natural language processing (e.g. "How long is John Doe?")
