The GT data has been labeled. The labeling is based on an ontology defined by the Pattern Recognition and Image Analysis Research Lab (PRImA-Research-Lab) at the University of Salford. This normalized and semantic description of the OCR-GT data can be found in the METS metadata file. The labeling metadata is created for each available page. The following labeling metadata is available for the complete collection.
Here you will find a description and explanation of the labeling metadata.
