摘要： In response to receiving a user inquiry describing one more symptoms of a medical condition, an online medical diagnosis system can determine one or more medical conditions related to the one or more symptoms. The online medical diagnosis system can include a parser to parse the user inquiry into keywords. The keywords can be looked up in a correlation graph model to determine a correlation of the keywords to one or more expert keywords. Keywords meeting a threshold correlation to expert keywords can be used to look up one or more medical conditions using an expert knowledge graph model. A user profile can be used to modify correlation values of keywords to expert keywords. The user profile can also be used to narrow the number medical conditions returned by the expert knowledge graph model. A medical resources crawler can use keywords parsed from stored user inquiries, and expert keywords, to update the correlation graph model.
