Claim 16:
17. A question answering method comprising:
determining a token representation of a question to be answered and token representations of candidate paragraphs of a present reasoning path for the question, respectively;
by a neural network module:
transforming the token representation of the question and the token representations of the candidate paragraphs of the present reasoning path into vector representations; and
appending a first variable to the vector representations to produce a second variable;

selecting the candidate paragraphs from a knowledge database to extend a present reasoning path based on lexical relevance of the candidate paragraphs to the question;
selectively add ones of the candidate paragraphs to the present reasoning path;
determining a score for the present reasoning path based on the second variable; and
selectively determining an answer to the question based on multiple different portions of the present reasoning path when the score of the present reasoning path is greater than a predetermined value.
