Our Take
TCI is the reference for Thai research — a national citation index that captures Thai journals the global indexes overlook and computes local impact metrics, and it pioneered the model now spreading across ASEAN. For Southeast Asian topics with a Thai research base it’s the primary source. It’s national and largely Thai-language. Use it to find and evaluate Thai journals directly; pair with the ASEAN Citation Index and OpenAlex for the wider regional picture.
Power Tips
- Search TCI directly for Thai research and use its tiered journal quartiles to judge a Thai source’s standing
- combine with the ASEAN Citation Index (ACI) for cross-border Southeast Asian coverage.
