Abstract

The invention provides a universal matching solution directed at the characteristics of service. ICD9 / 10 disease classification and surgical operation lexicons which are formed and accumulated by adopting natural language processing modes such as keyword extraction and part-of-speech tagging are adopted; a text matching degree in ICD9 / 10 related fields is high; and meanwhile, a personalized Elasticsearch analyzer is configured, so the full-text index hit rate and accuracy of the service are improved.

Description

technical field [0001] This application relates to the field of information retrieval, in particular to the field of full-text retrieval for medical information word segmentation thesaurus. Background technique [0002] With the advancement of medical informatization, hospitals have formed medical information systems such as HIS (Hospital Information System) and EMR (Electronic Medical Records). [0003] A large amount of unstructured data exists in medical information systems. Due to non-uniform coding standards, differences in doctors' idioms, and non-uniform design methods of cross-vendor information systems. For the classification of diseases, ICD (International Classification of Diseases, International Classification of Diseases) codes have been generated internationally for easy sharing and processing. [0004] As each medical institution adopts the same code in terms of data format and data content, it usually has unique personalized processing. Therefore, under no...
