Abstract: The present disclosure disclosures an artificial intelligence based method and apparatus for determining regional information. A specific embodiment of the method comprises: acquiring to-be-determined information, and extracting a keyword set of the to-be-determined information; inputting the keyword set of the to-be-determined information into a pre-trained subject classification model for classifying, to obtain a subject category of the to-be-determined information, wherein the subject classification model is used for representing a corresponding relation between the keyword set of the information and the subject category of the information; selecting, from a pre-stored place name set, a place name corresponding to the subject category of the to-be-determined information as a target place name set; matching, in the to-be-determined information, the target place name set; and determining, based on a matching result, whether the to-be-determined information belongs to the regional information.
