Problems solved by technology

First, the truth discovery method. In order to calculate the credibility of the answer and the knowledge level of the doctor, one possible way is to mark the quality of the answer and then learn a classification or regression model. However, this is a relatively professional field. , ordinary workers cannot effectively label samples, and workers with certain medical knowledge are required to label samples, which increases the cost of labeling. Realization; second, the purification of noise input, the medical questions and answers on the medical consultation website are all unstructured and noisy text data, which brings inconvenience to the reliability of the calculation and the doctor's knowledge level, in order to obtain more For good results, you need to better express the questions and answers; third, the long tail phenomenon, most questions only received two or three or even only one answer, which brings trouble to the screening of answers, because there are too few answers to screen It is meaningless, and these few answers are not even reasonable, so we need to find a way to expand the answer set; fourth, the correlation between the answers to the same question, the answer to the medical consultation question is not uniquely determined Yes, a question may have multiple reasonable and reliable answers, and these answers may have a relatively high similarity, which can also be an important basis for calculating the credibility of the answer
[0005] At present, most of the text mining of medical question-answering information focuses on the identification of medical named entities and the discovery of the relationship between entities, and eventually the potential medical knowledge in medical question-answer pairs can be obtained, but the quality of medical question-answering is not considered.
In reality, there are indeed some low-level doctors on medical question-and-answer websites, and even some doctors do not seriously answer patients' questions just to make money, so the quality of medical knowledge obtained is difficult to guarantee

Embodiment Construction

[0019] The invention proposes a method for extracting medical knowledge. The basic idea is to extract the "question-answer" pairs on the website and relevant information about doctors by means of automatic information extraction, and evaluate the credibility of the answers and the knowledge level of doctors through calculations to provide medical consultation questions. Screen out high-quality answers to form valuable medical knowledge. These medical knowledge have very important practical significance and can be used to construct the knowledge base of intelligent medical diagnosis system.

[0020] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0021] to combine figure 1 , including the following steps:

[0022] data collection. Select a specific medical and health consultation website, use the existing web crawler technology to crawl the medical question and answer information on the website and th...

Abstract

The invention discloses a method for aggregation and analysis of medical consultation information, which comprises the following steps: Step 1: Obtain medical information in the triple form of "question-answer-doctor" on an existing medical and health consultation website by means of web crawler technology; Step 2: Transform medical information in text format into entity-based structured data; Step 3: Calculate the similarity between structured questions, and merge questions with high similarity to expand the answer set of questions; Step 4: Use iteration The credibility of the answer is calculated in the same way, and the medical knowledge in the form of "question-answer-credibility" is obtained. The invention calculates the doctor's medical knowledge level and the reliability of the answer in an unsupervised manner, saves a lot of money and time costs, and thus obtains valuable medical knowledge.

Description

technical field [0001] The invention relates to the field of medical consultation, in particular to a method for aggregation and analysis of medical consultation information. Background technique [0002] With the development of society and economy, people's living standards are getting higher and higher, and people pay more attention to their health. The demand for authoritative health information is growing urgently. In recent years, with the rapid development of Internet, mobile Internet and other technologies, people are deeply involved in network knowledge production and online social interaction, and a large number of online question-answer consulting application systems have emerged. Among them, the medical crowdsourcing question-and-answer website is welcomed by the majority of users because it can conveniently provide timely first-diagnosis to patients. In foreign countries, such as medhelp.org in the United States, there are xywy.com and Baidu Thumb Doctor (muzhi....
