TSV - Processing Tools

Installation:

Setup virtual environment:

virtualenv --python=python3.6 venv

Activate virtual environment:

source venv/bin/activate

Upgrade pip:

pip install -U pip

Install package together with its dependencies in development mode:

pip install -e ./

PAGE-XML to TSV Transformation:

Create a TSV file from OCR in PAGE-XML format (with word segmentation):

page2tsv PAGE1.xml PAGE.tsv --image-url=http://link-to-corresponding-image-1

In order to create a TSV file for multiple PAGE XML files just perform successive calls of the tool using the same TSV file:

page2tsv PAGE1.xml PAGE.tsv --image-url=http://link-to-corresponding-image-1
page2tsv PAGE2.xml PAGE.tsv --image-url=http://link-to-corresponding-image-2
page2tsv PAGE3.xml PAGE.tsv --image-url=http://link-to-corresponding-image-3
page2tsv PAGE4.xml PAGE.tsv --image-url=http://link-to-corresponding-image-4
page2tsv PAGE5.xml PAGE.tsv --image-url=http://link-to-corresponding-image-5
...
...
...

For instance, for the file assets/example.xml:

page2tsv example.xml example.tsv --image-url=http://content.staatsbibliothek-berlin.de/zefys/SNP27646518-18800101-0-3-0-0/left,top,width,height/full/0/default.jpg
