Abstract

The invention discloses a text mining method and system based on unstructured electronic medical records. The method comprises the steps that multiple current medical history records derived from a hospital database serve as the original experimental data, and each sample is spread in a time series, words describing the meaning of time are identified at first, then long text is divided into several pieces of short text by taking a time node as boundary, that is to say, current medical histories are split into each hospital record; the features of the current medical history and extraction rules are determined and saved as an xml file; on the basis of medical history information extraction and structured storage, the defined rules are rewritten to form a regular expression to achieve feature extraction of unstructured text; quantitative representation of features is conducted, wherein by means of the data type of eigenvalue obtained after analysis and extraction, the eigenvalue is numerically quantified. The quantified eigenvalue is unified into the feature representation X=(x1, x2, x3, ..., x57) during one hospital stay, and then serves as the text features of an unsupervised clustering algorithm to implement text clustering.

Description

technical field [0001] The present disclosure relates to the technical field of natural language processing and machine learning, in particular to a text mining method and system based on unstructured electronic medical records. Background technique [0002] In Chinese Electronic Medical Record (EMR) data, main complaints, current medical history, past history, imaging reports, surgical records, etc. are mainly described in natural language, and collected and stored in structured and unstructured data formats. It is a concrete embodiment of clinicians' actual diagnosis and treatment details, including a comprehensive, professional and accurate description of patient health information, and is a valuable medical knowledge resource. Therefore, the structured processing and text mining of Chinese electronic medical records are of great significance to medical clinical auxiliary diagnosis and treatment. [0003] Currently, structured data in electronic medical records is stored...
