AI Technical Summary

Technical Problem

Conventional question answering methods cannot provide a basis for why a question cannot be answered, leading to incomplete information and reduced user understanding.

Method used

An information processing device equipped with a machine learning model that generates both answers and the basis for the inability to answer a question by analyzing multiple related texts, using techniques such as Fusion-In-Decoder (FiD) models, to output 'unanswerable' with evidence when necessary.

Benefits of technology

Enhances the reliability and robustness of answers by providing users with the reasons for unanswerable questions, allowing for question refinement and improved decision-making.

Abstract

Provided is an information processing device in which a first acquisition means acquires a query. A second acquisition means acquires a plurality of texts pertaining to the query. A generation means generates an answer and grounds for the answer from the query and the plurality of texts by using a machine learning model. Here, in case where an answer cannot be found for the query, the generation means generates the reason for being unable to answer from the plurality of texts. The information processing device can assist the decision making of a user by presenting the answer reason.
