Patent ID: 8386295

Claim:
A method for checking the correctness of GIS data, comprising the steps of: receiving GIS data; receiving business data of each branch of an enterprise; determining a geographic area to which each branch belongs, wherein the GIS data in the geographic area will be checked; and, checking whether the GIS data of the geographic area to which each branch belongs are correct based on the business data of each branch; and wherein the checking step further comprises the sub-steps of: extracting business data features that can reflect the business transaction amounts of the enterprise branches from the business data of the enterprise branches; extracting, from the GIS data in the geographic areas to which the enterprise branches belong, GIS data features that can reflect a contribution capability of the geographic areas to the business transaction amounts of the enterprise branches; determining whether the GIS data in the geographic areas to which the enterprise branches belong are correct based on a correlation model between the business data features and the GIS data features, calculating a basic score of each POI based on relevant demographic attributes of each type of POIs in each geographic area where an enterprise branch is situated, the basic score reflecting the contribution capability of the POI to the business transaction amounts of the enterprise branch, normalizing the basic score of each POI in each geographic area with respect to the basic scores of all POIs of a same type, thus obtaining a final score of each POI, and obtaining a weighted sum of each final score of all POIs in each geographic area based on the types they belong to, thus obtaining a total score of all POIs in each geographic area as the GIS data feature of each geographic area wherein at least one of the steps is carried out using a computer device.
