Public Syriac HTR Models on Transkribus: Benchmarks and Guidelines for Multi-Scripts

Syriac is now on Transkribus — and it works. The first public HTR models for this ancient Semitic script, covering both Serto and Estrangelo-Melkite hands, achieve a validated CER as low as 3.00%. This poster presents the technical journey from fixing fundamental Right-to-Left directional logic to releasing production-ready models, along with the Syriac HTR Guidelines that standardise how diacritics are handled. An essential resource for the global scholarly community working with Semitic manuscripts.
