Ground Truth is the basis of the creation of the Handwritten Text Recognition models. It is a typewritten copy of a document which is 100 % correct. It is used to train the A.I. Any mistake in the Ground Truth will train Transkribus to learn something wrong. Therefore, it is important that the Ground Truth is a document which is as close as possible to the original text. To ensure this, please refer to the Transkribus transcriptions conventions.
