Embodiment 1

[0090] as attached figure 1 Shown, the medical automatic question answering method of the present invention, this method comprises the steps:

[0091] S1. Build a medical question-and-answer knowledge base: crawl question-and-answer pairs from the Internet medical question-and-answer community, and preprocess the question-and-answer pairs to build a medical question-and-answer knowledge base;

[0092] S2. Build a question-and-answer model training data set; for each medical question, there are two correct answers in the medical question-and-answer knowledge base in step S1, construct a positive training example with the correct answers and questions, and combine answers and questions other than the correct answers Construct training negative examples; wherein, the number of negative examples is set according to the size of the medical question-and-answer knowledge base;

[0093] S3. Building a question answering model: constructing a question answering model using a convoluti...

Embodiment 2

[0160] as attached Figure 7 Shown, based on the medical automatic question answering device of embodiment 1, this device comprises:

[0161]The medical question and answer knowledge base construction unit is used to use crawler technology to crawl question and answer pairs from the medical question and answer community on the Internet, and preprocess the questions and answers of the medical question and answer knowledge base. Preprocessing includes splitting questions with multiple answers And hyphenate the content of questions and answers to build a medical question-and-answer knowledge base;

[0162] A question answering model training data set generation unit, used to construct training positive examples and training negative examples according to the medical question answering knowledge base, and then construct a training data set;

[0163] A question answering model construction unit, used to construct a character mapping conversion table, an input layer, a character ve...

Embodiment 3

[0183] A storage medium based on Embodiment 1, wherein a plurality of instructions are stored, and the instructions are loaded by a processor to execute the steps of the medical automatic question answering method of Embodiment 1.

Description

technical field [0001] The invention relates to the technical field of natural language processing and the field of computer artificial intelligence, in particular to a medical automatic question answering method and device, a storage medium, and electronic equipment. Background technique [0002] With the rapid development of the current Internet, the traditional medical industry has begun to embrace the Internet, and a large number of Q&A websites for patients have emerged. Among them, the online medical Q&A community has developed rapidly, because it greatly reduces the links for patients to seek help from doctors. Patients post questions in the Internet community, and doctors in relevant professions answer their questions, avoiding the process of going to the hospital, registering, and queuing in the traditional medical treatment process. However, with the increase in the number of users asking questions online, the increase in questions is much faster than the speed of ...
