The invention relates to a cognitive place feature recognition method for an urban subway station domain. The method comprises the steps of acquiring and preprocessing subway station and POI data are;removing POIs with abnormal coordinates; taking subway station names and surrounding POI addresses as search terms at the same time, and obtaining the cognitive intensity of the public to the subwaystation-surrounding POI relationship according to the number of co-occurrence webpages obtained by searching; according to the obtained cognitive intensity, extracting POIs having significant cognitive relationships with the subway station; extracting the boundary of the cognitive range of the subway station domain according to the extracted spatial position of the POI with significant cognitive relationship with the subway station; and recognizing cognitive semantic features of the subway station area according to the type of the POI in the cognitive range of the subway station area. The invention further relates to a cognitive place feature recognition system for the urban subway station area. The method pays attention to the cognitive place characteristics of the urban subway station area, extracts the cognitive range of the urban subway station area and identifies the semantic characteristics of the urban subway station area so as to serve geographic information retrieval, positionservice, urban planning and other applications.
