A medical fact verification method, performed by a computer, the method comprising: acquiring a medical fact to be verified and candidate evidence, wherein the medical fact to be verified comprises a target entity, a target attribute and a target attribute value, wherein the target attribute comprises at least one of a clinical feature, an etiology, a pathology, a therapeutic regimen, a recommended medication, a complication, and a drug effect, and the candidate evidence is retrieved from a designated medical database based on the medical fact to be verified; inputting the target entity, the target attribute value and the candidate evidence into an attribute decision model to obtain a decision attribute; inputting the target entity, the target attribute value and the candidate evidence into a relevancy decision model to obtain a relevancy of the candidate evidence in a case that the target attribute and the decision attribute are the same; and determining that the medical fact to be verified is correct in a case that the relevancy of the candidate evidence accords with a preset condition, and in a case where the medical fact to be verified is correct, adding the verified medical fact into a medical knowledge graph, to enrich the medical knowledge graph; wherein after inputting the target entity, the target attribute value and the candidate evidence into the attribute decision model to obtain the decision attribute, the method further comprises: determining that the candidate evidence cannot verify that the medical fact to be verified is correct in a case that the target attribute and the decision attribute are not the same. acquiring a medical fact to be verified and candidate evidence, wherein the medical fact to be verified comprises a target entity, a target attribute and a target attribute value, wherein the target attribute comprises at least one of a clinical feature, an etiology, a pathology, a therapeutic regimen, a recommended medication, a complication, and a drug effect, and the candidate evidence is retrieved from a designated medical database based on the medical fact to be verified; inputting the target entity, the target attribute value and the candidate evidence into an attribute decision model to obtain a decision attribute; inputting the target entity, the target attribute value and the candidate evidence into a relevancy decision model to obtain a relevancy of the candidate evidence in a case that the target attribute and the decision attribute are the same; and determining that the medical fact to be verified is correct in a case that the relevancy of the candidate evidence accords with a preset condition, and in a case where the medical fact to be verified is correct, adding the verified medical fact into a medical knowledge graph, to enrich the medical knowledge graph; wherein after inputting the target entity, the target attribute value and the candidate evidence into the attribute decision model to obtain the decision attribute, the method further comprises: determining that the candidate evidence cannot verify that the medical fact to be verified is correct in a case that the target attribute and the decision attribute are not the same.
