A method and system for matching answers to evidence in a question and answer scenario

Abstract

The application discloses a question and answer scene answering evidence matching method and system, wherein the method comprises the following steps: obtaining and splitting a target answer text to obtain a plurality of answer segments; identifying and labeling the role types corresponding to each answer segment based on logical roles to obtain corresponding target answer segments; generating a candidate evidence set corresponding to each target answer segment based on original evidence; matching the target answer segment with each evidence segment in the candidate evidence set corresponding thereto, selecting a target evidence segment corresponding to the target answer segment from the candidate evidence set based on the matching result; identifying the relationship type between the target answer segment and the corresponding target evidence segment, and establishing a segment-level mapping relationship; and performing linkage control on the corresponding target answer segment and target evidence segment based on the segment-level mapping relationship, and performing differential display based on the corresponding role type and relationship type. The application can clearly display the internal logical structure of the answer and the evidence supporting relationship.
