#### Data input format
The input data format is based on the format used in the [GermEval2014 Named Entity Recognition Shared Task](https://sites.google.com/site/germeval2014ner/data). Text is encoded as one token per line, with name spans encoded in the BIO-scheme, provided as tab-separated values:
* the first column contains either a `#`, which signals the source the sentence is cited from, or the token position within the sentence
* the first column contains either a `#`, which signals the source the sentence is cited from, or
* the token position within the sentence ``>=1``
* sentence boundaries are indicated by ``0``
* the second column contains the token text
* outer spans are encoded in the third column
* embedded spans are encoded in the fourth column
* the second column contains the token ``text``
* outer entity spans are encoded in the third column ``NE-TAG``
* embedded entity spans are encoded in the fourth column ``NE-EMB``
Example (simple):
```tsv
@ -42,9 +43,9 @@ No. TOKEN NE-TAG NE-EMB
```
For our purposes we extend this format by adding
* a fifth column for an identifier for the outer span from an authority file (in this case, the [GND](https://www.dnb.de/EN/Professionell/Standardisierung/GND/gnd_node.html) is used)
* column six for use as a variable
* finally, columns 7+ are used for storing pixel coordinates for facsimile snippets
* a fifth column for an ``ID`` for the outer ``NE-TAG`` from an authority file (in this case, the [GND](https://www.dnb.de/EN/Professionell/Standardisierung/GND/gnd_node.html) is used)
* column six for use as a variable ``url_id``
* finally, columns 7+ are used for storing ``left,right,top,bottom pixel`` coordinates for facsimile snippets
