This invention provides a land value verification device, a land value verification method, and a computer program that enable more accurate verification of land values. [Solution] The land price verification device includes an acquisition unit that acquires land prices and price formation factor data for each of the multiple routes included in the target area; a selection unit that selects a combination of two or more routes from the multiple routes as a verification route set; a verification unit that verifies the consistency of the land prices of each route based on the price formation factor data of each route included in the verification route set and outputs the verification result; and a storage control unit that stores the verification result in association with the verification route set.

This invention discloses an online intelligent assessment system for urban land value based on big data analysis, comprising: a data normalization module for acquiring and preprocessing multi-source heterogeneous data; an association mapping module for performing temporal registration, using data components as graph nodes and calculating association weights to construct a value association graph; a propagation solution module for locating nodes to be assessed, iteratively updating access probabilities along node connections to obtain an association propagation state sequence; an evolution and recombination module for performing multi-scale time window rearrangement, elevating to a linear evolution space and recursively recombinating to obtain the value evolution state; an inversion assessment module for variational Bayesian inversion, filtering out posterior state components and retaining posterior parameters to obtain the value assessment result; and an incremental update module for acquiring feedback data and incrementally updating the value association graph. This invention enables online intelligent assessment of urban land value, improving the accuracy of value assessment.
