Internet-based medical information retrieval system

The invention discloses a medical information retrieval system based on the Internet. The system comprises a medical information data set module, a database module, a medical information data retrieval module, a feedback module and a management module. By using a natural language processing technology and an information noise reduction algorithm, medical information can be efficiently and accurately extracted from a medical data information source, and useless or redundant information is removed, so that the efficiency and accuracy of subsequent processing are improved. The medical information can be classified, structured and stored in a medical information database by utilizing a structured conversion algorithm, so that medical professionals can better manage medical information data, and subsequent retrieval and analysis are facilitated; and by arranging the feedback module, when the retrieved content is too small or does not exist, the content is fed back to a manager, so that a database can be expanded i
