Problems solved by technology

[0003] It is well known that the recall rate and precision rate are the main indicators for evaluating information retrieval technology. However, in practice, even if all the information corresponding to the keyword is searched, due to the massive amount of information, it is often impossible for users to browse every One piece of information, that is, it is impossible to filter all the retrieved information; and even if all the information that matches the keyword is found, the found information often cannot meet the real needs of users
Especially for medical information retrieval technology, if the found information cannot solve the user's problem, or even false or unreliable medical information, it may cause irreparable damage to the user's physical and mental health

Embodiment Construction

[0039] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] The information retrieval technology involved in the present invention relates to information retrieval technology in a narrow sense, that is, according to the retrieval needs of information users, the process of using existing retrieval tools or databases to find out specific information is equivalent to what people call information query. Search). The basic principle of this kind of information retrieval is to compare the similarities and differences between the query features describing the information required by a specific user and the retrieval identifiers stored in the information, and find out the information that is consistent or basically consistent with the query features. At present, computer information retriev...
