Embodiment 1

[0028] Such as figure 1 As shown, the embodiment of the present application provides a two-way data value evaluation method for big data transactions, wherein the method includes:

[0029]S100: Obtain the first data commodity information of the transaction between the first data supplier and the first data purchaser;

[0030] S200: Input the first data product information into a feature extraction unit to obtain the first data product features;

[0031] Specifically, the first data supplier is a data supplier, the first data purchaser is a data buyer, and the goods traded between the two parties are data analysis results rather than data itself, and the transaction of data analysis results is the key point. Through the results of data cleaning, analysis, modeling, and visualization, the underlying data, that is, the first data commodity information is not directly traded, and the first data commodity information is input into the feature extraction unit to perform data commod...

Embodiment 2

[0078] Based on the same inventive concept as the two-way evaluation method of data value of a big data transaction in the previous embodiment, as Figure 7 As shown, the embodiment of the present application provides a two-way data value evaluation system for big data transactions, wherein the system includes:

[0079] A first obtaining unit 11, the first obtaining unit 11 is configured to obtain first data commodity information for transactions between the first data supplier and the first data purchaser;

[0080] A second obtaining unit 12, the second obtaining unit 12 is configured to input the first data product information into the feature extraction unit to obtain the first data product features;

[0081] A first construction unit 13, the first construction unit 13 is used to construct a first user demand analysis model and a first data quality assessment model;

[0082] A third obtaining unit 14, the third obtaining unit 14 is configured to input the first data commod...

Abstract

The invention provides a bidirectional evaluation method and system for data value of big data transaction, and the method comprises the steps: obtaining first data commodity information; obtaining first data commodity features; constructing a first user demand analysis model and a first data quality evaluation model; obtaining first demand matching information and first quality evaluation information; inputting the first demand matching information and the first quality evaluation information as variable information into a first objective function for calculation to obtain a first response result, and generating bidirectional value evaluation information according to the first response result, and sending the first value evaluation information and the second value evaluation information to the first data purchaser. The technical problems that in the prior art, the matching degree of transaction commodities and transaction requirements is low, transaction data pricing scientificity is insufficient, accurate evaluation of the value of the transaction commodities cannot be achieved, and the data value cannot be fully released are solved.

Description

technical field [0001] The invention relates to the technical field of data transactions, in particular to a method and system for bidirectional evaluation of data value in big data transactions. Background technique [0002] With the maturity and development of big data technology, the application of big data in business is more and more extensive, and the examples of interaction, integration, exchange and transaction of big data are also increasing. Big data exchanges have also emerged as the times require. The business scope of the big data exchange includes big data asset trading, big data financial derivative data design and related services; technology development such as big data cleaning and modeling; big data related financial leverage data design and services; Other businesses approved by the supervisory authority and relevant departments. The big data exchange will carry out data futures, data financing, data mortgage and other businesses for data vendors, estab...
