The invention is applicable to the technical field of computers, and provides a Dify
workflow-based
data extraction method, which comprises the following steps of: constructing a
nodal Dify
workflow; receiving an Excel file uploaded by a user through the file uploading node, and carrying out multi-
modal analysis on the Excel file through the
document analysis node to obtain multi-
modal data; matching predefined rules from the rule
knowledge base through
rule processing nodes, and performing dynamic matching in combination with multi-
modal data to generate a comprehensive rule set; through the multifunctional cooperative
processing node, in combination with the multi-
modal data and the comprehensive rule set, target fields are extracted from the Excel file in parallel from a multi-dimensional angle, and a multi-path extraction result is obtained; according to the method, the node is judged through decision, confidence coefficient aggregation is carried out on multiple paths of extraction results, the
data extraction result is determined according to the aggregation result, and a complex
data processing flow for Excel files with various formats is converted into an intuitive
workflow process, so that the development efficiency and the flow transparency are greatly improved.
