Alterra NLP Engine converts natural language questions or commands to formal queries a computer can understand.

It is powered by our phrase2vec sequence embedding algorithm. (It’s like word2vec, but for multiple-word queries.) Phraser semantic intent classifier and FAQ API QnA system are built on top of it. They are combined with our LSTM-based slot filler that extracts entities and parameters from phrases and returns them in a structured SQL-like format.
