Embodiment Construction

[0035]The invention is further illustrated in conjunction with the accompanying drawings and specific embodiments.

[0036]Such asfigure 1As shown, a machine reading comprehension method based on multitasking joint training, including model construction and training phase, test phase;

[0037]The model build and training phase include the following steps:

[0038]Step 1, build training sets, including the following steps:

[0039](1.1) Collecting training materials, the training media includes articles, based on the problems of the article, the answer of the problem;

[0040](1.2) Preprocessing the training language, the pretreatment includes converting traditional Chinese characters to simplicity words, full-horn numbers, and all-angle letters to half-angle numbers and half-angle letters, remove the punctuation of the first position of the answer, removing the problem in training media Or the article is empty, remove the problem and the same corpus;

[0041](1.3) When the article is long, the existi...

Abstract

The invention discloses a machine reading comprehension method based on multi-task joint training and a computer storage medium, wherein the method includes a model building and training phase, and a testing phase; the model building and training phase includes: 1. Building a training set; 2. Establish a machine reading comprehension model, including an encoding layer, an attention matching layer, and a decoding layer; 3. Divide the training set into W sub-sample sets according to the number of samples, and use W sub-sample sets to train the machine reading comprehension model to obtain W Machine reading comprehension model; the test stage includes: truncating the article to be tested, and inputting the processed article and question into the trained W machine reading comprehension models to obtain W predicted answer start positions and end positions And the corresponding distribution probability, calculate the mean value as the starting position, ending position and corresponding distribution probability of the final answer. This method can solve the problems of low accuracy of Chinese texts in existing machine reading comprehension methods.

Description

Technical field[0001]The present invention belongs to the technical field of machine learning, and in particular, the present invention relates to a machine reading comprehension method and a computer storage medium.Background technique[0002]Let the machine to complete reading comprehension and question and answer are a hot topic of the current Ai-bound edge, mainly involving deep learning, natural language processing and information retrieval. Machine reading understandings have a high research value in the industry or academic community, which allows computers to help humans find the answer you want in a large number of texts, thereby alleviating the cost of people's acquisition. Perhaps, the future search engine will not only return to the user-related links and web pages, but by reading a massive resource on the Internet, they directly give the answer to the user.[0003]At present, the extraction-based reading comprehension task is relatively mature, and the reading comprehension...
