Claim 19:
20. A question answering system comprising:
a first means for 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;
a second means for:
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;

a third means for:
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; and
selectively adding ones of the candidate paragraphs to the present reasoning path,

wherein the second means is further for determining a score for the present reasoning path based on the second variable; and
a fourth means for 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.
