Title: Data resource valuation method for network platform
Inventor: XIA GAO
IPC: G06Q30/02
Filed: 2021-04-14
Abstract: The present disclosure relates to a data resource valuation method for a network platform. The method includes: 1: constructing a data resource valuation index system under a network platform—based trading environment; 2: determining an evaluation index weight according to an entropy correction G1 method; 3: prescreening, according to a grey correlation analysis (GCA) method, traded data resources on a network platform; and obtaining traded data resources whose degrees of correlation with pre-evaluated data resources are greater than or equal to a threshold, to constitute a model sample set T; and 4: selecting a random forest regression (RFR) model as a basic data resource valuation model of the network platform, and using the model sample set T to construct a data resource valuation model. Evaluation indexes of the pre-evaluated data resources are input into the data resource valuation model, and an average value of output values of all regression trees is used as a result of data resource valuation performed based on the data resource valuation model. The present disclosure not only can remarkably improve accuracy of data resource value prediction, but also can reduce an amount of calculation of the RFR model and improve training efficiency of the RFR model.
