Information extraction method and device based on medical guide

The invention discloses an information extraction method and device based on a medical guideline, and the method comprises the steps: recognizing a document logic structure of the medical guideline, generating a structural vector of the medical guideline, and extracting a medical record structural vector of a target user, so that the structural vector of the medical guideline and the medical record structural vector of the target user can be utilized, and the information extraction efficiency is improved. Determining a target scheme corresponding to the medical record information in the medical guide and a content link corresponding to the target scheme; therefore, according to the embodiment, the document fragment (namely the target scheme corresponding to the medical record information in the medical guide) most matched with the medical record information can be found out more quickly and accurately, doctors and medical care providers are helped to locate related content in the medical guide more easily, an
