The invention provides a multi-data-source-oriented diagnosis and treatment class entity identification method and apparatus, and relates to the technical field of medical entity identification. The method comprises the steps of obtaining a to-be-processed statement in original data; performing single word segmentation on the to-be-processed statement, and determining each text in the to-be-processed statement; according to a pre-trained CRF training model, determining an entity mark, in the to-be-processed statement, of each text in the to-be-processed statement, and determining an entity mark sequence of the to-be-processed statement; according to the entity mark sequence of the to-be-processed statement, determining a first group of candidate entities of the to-be-processed statement; according to a preset diagnosis and treatment class term segmentation policy, performing term segmentation on the to-be-processed statement, and determining a second group of candidate entities; screening the candidate entities to form a first group of candidate diagnosis and treatment class entities and a second group of candidate diagnosis and treatment class entities; and according to a preset judgment policy, determining a diagnosis and treatment class entity result in the first group of the candidate diagnosis and treatment class entities and the second group of the candidate diagnosis and treatment class entities.
Description
technical field [0001] The invention relates to the technical field of medical entity recognition, in particular to a multi-data source-oriented diagnosis and treatment entity recognition method and device. Background technique [0002] At present, with the development of network and medical information technology, the gradual aging of the Chinese population, and the gradual rise of Internet medical care, big data in the medical and health industry has also been generated one after another. In the actual clinical diagnosis and treatment process, a large amount of diagnosis and treatment information is generated every day. The utilization and research of these diagnosis and treatment information play an important role in fields such as medical statistics, scientific research, teaching, and medical management. Due to the massive quantity and various structures of medical information, it is almost impossible to identify medical information only by human power, and then conduct ...
