# Fine-tuned Flair Model on Dutch ICDAR-Europeana NER Dataset

This Flair model was fine-tuned on the
[Dutch ICDAR-Europeana](https://github.com/stefan-it/historic-domain-adaptation-icdar)
NER Dataset using hmBERT Tiny as backbone LM.

The ICDAR-Europeana NER Dataset is a preprocessed variant of the
[Europeana NER Corpora](https://github.com/EuropeanaNewspapers/ner-corpora) for Dutch and French.

The following NEs were annotated: `PER`, `LOC` and `ORG`.

# Results

We performed a hyper-parameter search over the following parameters with 5 different seeds per configuration:

* Batch Sizes: `[4, 8]`
* Learning Rates: `[5e-05, 3e-05]`

And report micro F1-score on development set:

| Configuration     | Seed 1       | Seed 2           | Seed 3       | Seed 4       | Seed 5       | Average         |
|-------------------|--------------|------------------|--------------|--------------|--------------|-----------------|
| `bs4-e10-lr5e-05` | [0.5572][1]  | [0.5434][2]      | [0.5984][3]  | [0.5636][4]  | [0.5674][5]  | 0.566 ± 0.0203  |
| `bs8-e10-lr5e-05` | [0.5072][6]  | [0.5287][7]      | [0.5641][8]  | [0.5438][9]  | [0.5346][10] | 0.5357 ± 0.0208 |
| `bs4-e10-lr3e-05` | [0.519][11]  | [0.471][12]      | [0.5479][13] | [0.498][14]  | [0.4977][15] | 0.5067 ± 0.0286 |
| `bs8-e10-lr3e-05` | [0.4817][16] | [**0.4511**][17] | [0.4956][18] | [0.4627][19] | [0.4715][20] | 0.4725 ± 0.0171 |
