Abstract

The invention provides a general matching solution aimed at business characteristics. The ICD9 / 10 disease classification and surgical operation lexicon formed and accumulated by natural language processing methods such as keyword extraction and part-of-speech tagging have a high degree of matching of texts in ICD9 / 10 related fields. At the same time, a personalized Elasticsearch analyzer is configured to improve targeting The full-text index hit rate and accuracy rate of the service.

Description

technical field [0001] The present 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 the medical information system. Due to inconsistent coding standards, differences in doctors' idioms, and inconsistent design methods for cross-vendor information systems. For disease classification, ICD (International Classification of Diseases, International Classification of Diseases) codes have been produced internationally for easy sharing and processing. [0004] Due to the data format and data content of each medical institution, even if the same code is used, there will usually be unique personalized processing. ...
