The present application relates to the technical field of audit
data integration, and specifically relates to a heterogeneous
data integration method for off-site audit, a
computer device and a medium. For different data groups in a single
data type, the method identifies data groups with missing collection and combines the data groups with missing collection, and identifies data groups with repeated collection and combines the data groups with repeated collection, to obtain merged data corresponding to each
data type. Based on the merged data, the method performs
natural language processing and one-hot encoding on data of different data types, forms
column vector combinations between different data categories of each
data type, analyzes the matching degree between any two column vectors in the
column vector combinations corresponding to different data types, obtains matching column vectors of the column vectors, and completes the integration between the same data categories in different data types. When performing off-site audit on the integrated data,
data classification analysis can be more convenient, and the audit efficiency and accuracy can be improved.
