AI Technical Summary

Technical Problem

The existing data quality evaluation methods have problems with weight allocation subjectivity and security of centralized evaluation nodes, and it is difficult to adapt to data needs in different scenarios.

Method used

The weight of the multidimensional data quality evaluation model is determined by using the analysis of hierarchy (AHP) and stored on the blockchain. The immutable and decentralized characteristics of the blockchain are used, and the dynamic evaluation and incentive mechanism are realized by combining the hyperbolic incentive mechanism and smart contracts.

Benefits of technology

It improves the transparency and credibility of data quality evaluation, solves the subjectivity problem of weight allocation, avoids the risk of tampering by centralized nodes, promotes high-quality data sharing, and optimizes the data sharing ecosystem.

Abstract

The invention relates to a data quality assessment method and device based on AHP and blockchain, and the method comprises the steps: constructing a multi-dimensional data quality assessment model, determining the weight of each dimension index in the multi-dimensional data quality assessment model through an analytic hierarchy process, and carrying out the chaining storage of the weight of each dimension index; the dimension indexes of the multi-dimensional data quality evaluation model comprise a metadata integrity index, a data integrity index, a data accuracy index, a data redundancy index, a historical scoring index and a data timeliness index; executing the multi-dimensional data quality evaluation model by the block chain smart contract, performing quality evaluation of the shared data, and storing an evaluation result to the block chain; the weight of the multi-dimensional data quality evaluation model is determined through an analytic hierarchy process, the problem that the weight of an existing method is high in subjectivity is solved, the weight is stored in a chained mode, evaluation is executed through an intelligent contract, the safety is improved through block chain characteristics, and the multi-dimensional model can adapt to multi-scene data requirements.
