Problems solved by technology

[0004] It can be seen that the existing question answering methods only support inputting questions into the question answering model in the form of text or voice, which has relatively large limitations, and the sentences determined by similarity calculation can only show that they are similar to the question and may be the source of the question , it may also be a similar question, and it is not necessarily the answer to this question. Therefore, the accuracy of the answer determined by the above method is low

Abstract

The invention provides a question answering method and device, and the method comprises the steps: extracting a first image feature and a second image feature of a target image, and a text feature of a target question, and enabling the dimension of the first image feature to be lower than that of the second image feature; performing attention analysis on the first image feature to obtain an attention coefficient, and determining a third image feature according to the second image feature and the attention coefficient; and determining a target answer of the target question based on the text feature and the third image feature. In the method, a more accurate attention coefficient can be determined through a first image feature including more image detail information, then a third image feature is determined according to a second image feature and the attention coefficient, and the third image feature carries the attention coefficient and a target answer determined based on a text feature and the third image feature. The accuracy of the target answer can be improved.

Description

technical field [0001] The present application relates to the technical field of natural language processing, and in particular, to a question answering method. The present application also relates to a question and answer device, a computing device, and a computer-readable storage medium. Background technique [0002] Artificial intelligence (AI) refers to the ability of an engineered (ie designed and manufactured) system to perceive the environment and to acquire, process, apply and represent knowledge. Natural Language Processing (NLP, Natural Language Processing) is an important direction in the field of computer science and artificial intelligence. It refers to the use of computers to process the shape, sound, meaning and other information of natural language. The operation and processing of input, output, recognition, analysis, understanding, generation, etc., it studies various theories and methods that can realize effective communication between humans and computers...
