Text-Image Alignment: from alignment to enhancement

The first batch of our ground-truth and images has been processed. That are 489 pages, 7100 lines, 132’700 words! All on HD images provided by the French National Archive and based on the text edition by Paul Guérin. We now are able to see the text on the image :
Aligned text and image at word level on Paris, Archives Nationales, JJ 35, fol. 18v

From then on, we are now working on
1) the validation/correction of the alignment or segmentation… and here we have to acknowledge that our “ground-truth” was far from being 100% accurate (some links to images were wrong, some text paragraphs were omitted by Paul Guérin, and all sorts of funny discoveries)
2) the enhancement of the text edition, esp. by enriching it with the abbreviations as to create better models and a better ground-truth. For that, we have played with a little tool, which indicates which abbrevations are possible for a given word :
