As part of the work to build optical models, A2iA applied the techniques developped in the Oriflamms project to automatically align text and image, and extract each occurrence of any particular letter.
This is always a great fun for palaeographers to see this happening 🙂
The research project started on November 1st, 2015. We are now describing the first steps undertaken during the first 3 months of the HIMANIS project are the following: the partners created the CHANCERY corpus (Archives nationales, JJ 35 to JJ 91) and associated the ground-truth with the images. They also acquired the necessary linguistic resources and formatted them in order to apply them to the automated indexing. At the same time, they created a dictionary of named entities with a dual objective: on the one hand, allow for a better indexing, and, on the other hand, provide a tool for accuracy measure. This dictionary is mainly based on the diverse regional systematic surveys : Gascogne; Languedoc and Rouergue; Berry, Blésois, Chartrain, Orléanais, Touraine.
While working on these resources, we are moving from a linear and self-contained work and go to a direct index to spot on which page of which register, one can find a specific named entity.
The ground-truth is drawn from the large collection of Paul Guérin, Recueil des documents concernant le Poitou contenus dans les registres de la Chancellerie de France, 12 vol.
