KG2Cypher: Data-Centric Pipeline for Building Enterprise Text-to-Cypher Systems
KG2Cypher addresses a real enterprise pain point: converting private knowledge graphs into natural-language interfaces without massive annotation overhead. The system inverts the typical pipeline by generating synthetic training data from existing graph structure, then validates outputs through LLM judges and human review before fine-tuning. This data-centric approach reduces the cost barrier for deploying text-to-query systems in corporate settings, particularly relevant as enterprises embed knowledge graphs deeper into search and analytics workflows. The Korean enterprise validation signals growing adoption outside Western tech hubs.

ExplainerThe key insight is the inversion itself: instead of collecting labeled text-to-query pairs from humans (expensive), KG2Cypher generates synthetic training data directly from graph structure, then uses LLM judges to filter before human review. This flips the annotation bottleneck from data collection to data validation.
This connects directly to the SHIFT paper from the same day, which also tackles the tension between learned model knowledge and external grounding (in that case, retrieved context conflicting with parameters). KG2Cypher solves a related reliability problem for enterprise systems: how to ground language models in structured knowledge without massive labeling overhead. Both papers treat grounding as a solvable engineering problem rather than an inherent model limitation. The temporal fusion NER work also shares the underlying concern with domain-specific adaptation, though KG2Cypher targets a different modality (structured queries rather than temporal metadata).
If KG2Cypher's validation approach (LLM judge + human review) produces query accuracy above 90% on held-out enterprise graphs without domain-specific prompt engineering, that confirms the synthetic-data-first model generalizes. If accuracy drops below 85% when tested on graph schemas the system hasn't seen during training, the approach is overfitting to graph topology rather than learning robust text-to-query reasoning.
