# 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 [example.xml](https://github.com/qurator-spk/page2tsv/blob/master/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
```

## Processing of already existing TSV files:

Create a URL-annotated TSV file from an existing TSV file:

```
annotate-tsv enp_DE.tsv enp_DE-annotated.tsv
```
