Claim 18:
19. A question answering method comprising:
by one or more processors, receiving a question from a computing device via a network, the question including a first plurality of words, and to encode the question into a first vector representation;
by the one or more processors, encoding a document D into a second vector representation, the document including a second plurality of words;
by the one or more processors, generating a third vector representation based on the first and second vector representations;
by the one or more processors, generating a first reformulated vector representation for the question based on the first vector representation;
by the one or more processors, generating a fourth vector representation based on the second vector representation and the first reformulated vector representation;
by the one or more processors, generating a second reformulated vector representation for the question based on first reformulated vector representation;
by the one or more processors, determining an answer to the question based on the second reformulated vector representation; and
by the one or more processors, transmitting the answer to the computing device via the network,
by the one or more processors, determining (a) first and (b) second sets of probabilities that represent (a) a probability of each word of the document being a beginning of an answer span and (b) a probability of each word of the document being an end of the answer span, respectively, the answer span being a span of words of the document that correctly answers the question; and
by the one or more processors, based on the first and second sets of probabilities, determining an attention vector of probabilities of entries of the second vector representation being part of the answer span.
