This presentation examines the applicability of ground truth for handwritten text recognition (HTR) on Nepalese manuscripts written in the Pracalit script (which is commonly used for Sanskrit and Newar manuscripts dating from approximately the 16th to 20th centuries) to use on an earlier Nepalese script, Bhujimol (which was prevalent from the 11th to 17th centuries). The presentation will outline several strategies identified as effective for adapting ground-truth data from one script to a similar script, and will discuss the broader relevance and significance of such models for scholarly research and cultural preservation.
