Problems solved by technology
However, after searching through the above methods, a lot of search results will be obtained, and there is no way to further screen the most relevant literature information, and manual screening will be very time-consuming and laborious
Although the search results can be reduced by increasing the number of search terms, it is easy to miss the highly relevant documents in this case
[0003] In addition, for different users, there will be differences in the degree of understanding of medical knowledge. It is not that the more relevant literature is more useful to users, it is related to the user's knowledge level, and the existing medical databases are not aimed at this. take corresponding countermeasures

Embodiment Construction
[0019] In order to illustrate the present invention more clearly, a specific implementation is described below, and the method of using the medical database established by this implementation is also explained.
[0020] 1. Index establishment
[0021] 1.1. Recorded index fields
[0022] 1.1.1. Full-text search index
[0023] To establish a full-text retrieval system, the source document must first be converted into a full-text database capable of text search, including full-text segmentation processing and standardized format, that is, pre-processing. Typesetting symbols, format control characters, etc. in the source document, and then record the information up to the occurrence of each word, word, and phrase in the source document into the index library.
[0024] 1.1.2. Indexing index and feature word index
[0025] The index words of the full-text search all come from the content of the document, but when the search keyword entered by the user is a synonym or alias of the...

The invention provides a method for establishing a medical database, comprising the following the steps of: (1) transforming a source document into full text data capable of being subjected to text searching so as to establish the following retrieval indexes: a. a full text retrieval index, b. a comments index, c. a literature external characteristic index, d. and a difficulty level grading index; (2) and selecting part of the retrieval indexes for weighting distribution so as to establish a weighted grading and sequencing program based on the appearing frequency of searched words. The medical database established by using the method of the invention is capable of retrieving medical literatures, which have high correlation degree and are suitable to users, according to the intellectual level of the users. The method for establishing the medical database is capable of greatly improving retrieval efficiency, and is convenient to use for the users with different levels of medical knowledge.
Description
technical field [0001] The invention relates to a method for establishing a medical database (that is, a medical document retrieval system). Background technique [0002] Existing medical databases are established based on the most conventional retrieval methods, most of which are keyword retrieval or simple combined retrieval using Boolean logic operations. However, after searching through the above methods, there will be a lot of search results, and there is no way to further screen the most relevant literature information, and manual screening will be very time-consuming and laborious. Although the search results can be reduced by increasing the number of search terms, it is easy to miss the highly relevant documents in this case. [0003] In addition, for different users, there will be differences in the degree of understanding of medical knowledge. It is not that the more relevant literature is more useful to users, it is related to the user's knowledge level, and the ...
