Abstract

The invention provides a similar case text retrieval system. The similar case text retrieval system comprises a server and a client which are in communication connection; m case records are stored inthe server, the i-th case record comprises a record ID, a disease ID and a word vector set Wi = (Wi1, Wi2,..., Win), and Win is the n-th word in the word vector set Wi. The client comprises a processor and a display interface, and the processor is used for realizing the following steps: receiving input text information and generating a word vector set W = (W1, W2,..., Wn) from the text information; determining the similarity of W and Wi; and outputting a corresponding retrieval result on the display interface according to the obtained similarity Si. According to the invention, the retrieval efficiency can be improved and the retrieval result is ensured to be more accurate.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a similar case text retrieval system. Background technique [0002] Patent Document 1 (CN107657062A) provides a similar case retrieval method, which includes: by extracting multiple field contents of multiple cases in the case database and converting the multiple field contents into word vectors, according to the word vectors, multiple The above cases are clustered and divided into multiple clusters; the field content in the original medical record is extracted and the field content is converted into the original word vector; the cluster closest to the original word vector is searched, and the multiple clusters in the cluster are Cases are sorted and given feedback. This method can reduce the amount of data calculation during retrieval and improve retrieval efficiency. However, it does not deal with the characteristics of the case text, but processes the case text as a g...
