Research on online book user purchase behavior based on the event logic graph

The innovation lies in integrating Top2Vec theme clustering with ELG visualization technology, establishing a "semantic aggregation + logical deduction" research paradigm for consumer behavior. Limitations include the potential for small sample themes to weaken the explanatory power for group heterogeneity, and the research scope being currently confined to the "purchase behavior" stage without extending to the entire reading lifecycle. Future research should deepen conclusions by expanding data dimensions and scenario boundaries.
