The invention provides an
intelligent decision-making method and device for cross-
modal data, equipment and a storage medium, and the method comprises the steps: carrying out the
blockchain storage of collected multi-
modal process data, and generating an on-chain hash
certificate; performing cross-
modal space-
time alignment and
feature fusion on the multi-modal process data according to the space-time
metadata analyzed by the Hash
certificate on the chain to generate a
process knowledge graph; constructing an interactive teaching model according to the
process knowledge graph; determining a multi-dimensional contribution measurement value according to the use data of the interactive teaching model; and based on the multi-dimensional contribution magnitude and the hierarchical
smart contract architecture, determining the
data access permission through a
community voting mechanism. Through implementation of the scheme, the
process knowledge graph and the interactive teaching model, the inheritor operation data and the material response data form a causal
association model, a traceable decision basis is provided for accurate
reproduction of an endangered process, and meanwhile, the intelligent contract can automatically execute a decision to ensure high efficiency and transparency of the
decision process.
