The application discloses an intelligent marketing document generation device and method based on multi-
source data fusion, and the method comprises four processes: user instruction analysis, regular cleaning,
model extraction parameter, Neo4j
knowledge graph verification, and output of structured parameters;
external data acquisition, parameter calling of a Baidu
large model to collect data, de-duplication,
semantic enhancement, and weighted screening of high-
quality data; internal case
processing, regular
slicing of case storage, filtering, propagation calculation, multi-dimensional scoring, and generation of a CoT reasoning chain report; multi-
modal output, format
adaptation,
data integration by a BART model, and output of a
metadata document. The device and the method are coordinated, multi-source fusion,
knowledge graph association and multi-
modal conversion are realized, high-quality marketing documents suitable for multiple industries are efficiently generated, decision-making is supported, and the
