Medical entity relation extraction is of great significance for medical text data mining and medical knowledge graph. However, medical field requires very high data accuracy rate, the current medical entity relation extraction system is difficult to achieve the required accuracy. A main technical difficulty lies in how to obtain high-precision medical data, and automatically generate annotated training sample set. In this paper, a medical entity relation automatic extraction system based on weak supervision is proposed. At first, we designed a visual annotation tool, it can automatically generate crawl scripts, crawling the medical data from the site where the entity and its attributes are Separate stored. Then, based on the acquired data structure, we propose a weakly supervised hypothesis to automatically generate positive sample training data. Finally, we use CNN model to extract medical entity relation. Experiments show that the method is feasible and accurate. |
