Struct-Bench: A Benchmark for Differentially Private Structured Text Generation
Struct-Bench introduces a novel framework and benchmark for evaluating differentially private (DP) synthetic data generation, particularly for structured datasets with natural language components. Current methods struggle with structural properties and correlations. Struct-Bench leverages Context-Free Grammars (CFGs) to define data structure and offers metrics for syntactic and semantic quality, as well as downstream task performance. The benchmark includes seven diverse datasets and evaluates state-of-the-art DP generation techniques, highlighting their limitations in capturing complex data structures without sacrificing semantic integrity. A case study demonstrates how Struct-Bench can guide improvements in methods like Private Evolution (PE) to achieve near 100% structural compliance and enhanced semantic performance.

Structural Metrics
This category focuses on metrics that assess how well the synthetic data adheres to the specified structural rules defined by the Context-Free Grammar (CFG). It includes CFG Pass Rate (CFG-PR), Key Node Dependency (KND), and Attribute Match (AM).
Non-Structural Metrics
These metrics evaluate the semantic quality and diversity of the generated text, independent of the CFG. They include KNN-Precision and KNN-Recall, which measure the semantic similarity and coverage of the synthetic data compared to the real data.
Downstream Task Accuracy
This section measures the utility of the synthetic data for specific enterprise applications. It evaluates the accuracy of models trained on synthetic data when performing tasks like topic prediction, intent classification, or income prediction on real data.

Private Evolution (PE) Enhancement
Using Struct-Bench's insights, we significantly improved Private Evolution (PE)'s performance. By implementing LLM-assisted reformatting, PE's CFG-PR on ShareGPT increased by over 20%. Node extraction and auto-generation further boosted semantic diversity (KNN-Recall), demonstrating how targeted interventions guided by Struct-Bench lead to superior differentially private synthetic data generation.
Key Outcome: Near 100% structural compliance and enhanced semantic diversity for PE.
