Assignee: NAVER CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 16:
17. A training system comprising:
a question answering system comprising:
a first encoder module configured to receive 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;
a second encoder module configured to encode a document D into a second vector representation, the document including a second plurality of words;
a first reading module configured to generate a third vector representation based on the first and second vector representations;
a first reformulation module configured to generate a first reformulated vector representation for the question based on the first vector representation;
a second reading module configured to generate a fourth vector representation based on the second vector representation and the first reformulated vector representation;
a second reformulation module configured to generate a second reformulated vector representation for the question based on first reformulated vector representation; and
an answer module configured to determine an answer to the question based on the second reformulated vector representation and to transmit the answer to the computing device via the network; and

a training module configured to train the question answering system by minimizing a first loss regarding facts support answers to questions, a second loss regarding spans of words, and a third loss regarding classification of answers.
