Table 1 Research positioning relative to existing literature.
Dimension | Existing studies | This research |
|---|---|---|
AI architecture | General-purpose diffusion models; domain-agnostic fine-tuning | Cultural-aware attention mechanism; domain-specific loss functions; ablation-validated improvements |
Participatory mechanism | Isolated user studies; short-term experiments | CPDC theoretical framework; six-month longitudinal study; multi-level participation design |
Cultural evaluation | Subjective expert assessment; single-dimension metrics | Multi-dimensional evaluation system; inter-rater reliability validated; quantitative diversity indices |
Copyright protection | Conceptual discussions; centralized systems | Blockchain-based framework; Shapley value allocation (conceptual with preliminary validation) |
Empirical validation | Small samples; cross-sectional designs | 486 participants; longitudinal design; statistical causal analysis |
Generalizability claims | Often overstated | Explicit distinction between framework transferability and empirical result generalizability |
