Description

HTR model for Old Swedish following a modified TRIDIS (https://hal.science/hal-05008780v1/file/TRIDIS_dataset_HTR.pdf) Transcription Guideline customised for the Swedish National Archives' medieval letter material written in Old Swedish. Persons and places are capitalised (entity capitalisation); punctuation is standardised; consonantal "i" and "u" has been transcribed as "j" and "v", for instance: "iac" --> "jac", “j biscops” --> "i biscops". Abbreviations are expanded and resolved. While this model is not perfect, it serves as a useful starting place to speed up transcription of medieval letters written in Old Swedish. With more training data, accuracy is likely to improve further. The base model that this HTR model is finetuned on is the "German_Gothic_Scripts_14th-16th_century" available on Transkribus.

Measured on the model's own validation data. Results on your documents may differ depending on handwriting style, document condition, language, and how closely your material resembles the training data.
