  • Patent number: 12050632
    Abstract: A question answering method that is performed by a question answering apparatus includes: receiving a data set including video content and question-answer pairs; generating input time-series sequences from the video content of the input data set and also generating a question-answer time-series sequence from the question-answer pair of the input data set; calculating weights by associating the input time-series sequence with the question-answer time-series sequence and also calculating first result values by performing operations on the calculated weights and the input time-series sequences; calculating second result values by paying attention to portions of the input time-series sequences that are directly related to characters appearing in questions and answers; and calculating third result values by concatenating the time-series sequences, the first result values, the second result values, and Boolean flags and selecting a final answer based on the third result values.

  • Patent number: 12051012
    Abstract: There are proposed a method and system for information theory-based questioning for a goal-oriented dialog system. An information theory-based question provision system includes an approximate answer generation unit configured to generate an approximate answer by approximating the generation of an answer to a question by an answer module constituting a part of the goal-oriented dialog system; an intention inference unit configured to infer an intention value, which is the degree of proximity of the question to a goal, based on the answer of the answer module, and a question provision unit configured to provide a question to the answer module based on the intention value.

  • Publication number: 20240070492
    Abstract: Disclosed herein are a reasoning method based on a structural attention mechanism for knowledge-based question answering and a computing apparatus for performing the reasoning method. The reasoning method includes: recognizing one or more entities in a query including content and a question, and linking the recognized entities to a knowledge base; constructing a question hypergraph and a query-aware knowledge hypergraph by performing a multi-hop graph walk on a question graph and the knowledge base; and inferring a correct answer to the question by applying as attention mechanism to a query hyperedge and a knowledge hyperedge included in the question hypergraph and the query-aware knowledge hypergraph, respectively.

  • Patent number: 11188774
    Abstract: There are proposed an attention memory method and system for locating an object through visual dialogue. The attention memory system for identifying an object on an image includes: a control unit which generates a question for identifying a preset object on the image, derives an answer to the generated question, and identifies the preset object on the image based on the question and the answer; and memory which stores the image. The control unit generates the question by incorporating information about objects included in the image into the question, and updates the information about the objects based on the answer.
