The application discloses an online medical intelligent doctor guiding
system based on
text graph embedding and belongs to the technical field of
medical doctor guiding. Through fine-grained medical entity recognition and
ambiguity resolution on online
medical consultation texts, fine-grained entities can be accurately recognized, and the problem of fine semantic
granularity can be solved. Through matching of a medical dictionary and context, the
ambiguity generated by the entity can be effectively eliminated. Through a dynamic updating mechanism, the latest
medical knowledge can be ensured to be incorporated into the graph, and the knowledge can be prevented from being outdated. From text preprocessing to graph construction, a complete link is formed, which can provide a high-quality
knowledge base for subsequent
graph embedding and doctor guiding reasoning. The entity vector obtained through
processing contains graph structure, deep
semantics and clinical logic, and can effectively solve the defects of single mode of traditional embedding. Through a constraint
loss function, the vector can be ensured to conform to the path rules of authoritative clinical guidelines, clinical logic consistency can be realized, and vectors that violate medical common sense can be avoided.
