# Fine-tuned Flair Model on AjMC German NER Dataset (HIPE-2022)

This Flair model was fine-tuned on the
[AjMC German](https://github.com/hipe-eval/HIPE-2022-data/blob/main/documentation/README-ajmc.md)
NER Dataset using hmBERT 64k as backbone LM.

The AjMC dataset consists of NE-annotated historical commentaries in the field of Classics,
and was created in the context of the [Ajax MultiCommentary](https://mromanello.github.io/ajax-multi-commentary/)
project.

The following NEs were annotated: `pers`, `work`, `loc`, `object`, `date` and `scope`.

# 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-lr3e-05` | [0.8806][1]  | [0.8988][2]      | [0.8967][3]  | [0.8924][4] | [0.8994][5]  | 0.8936 ± 0.0078 |
| `bs8-e10-lr5e-05` | [0.8951][6]  | [0.8972][7]      | [0.8933][8]  | [0.8892][9] | [0.8902][10] | 0.893 ± 0.0033  |
| `bs4-e10-lr5e-05` | [0.8789][11] | [0.891][12]      | [0.9012][13] | [0.891][14] | [0.8873][15] | 0.8899 ± 0.008  |
| `bs8-e10-lr3e-05` | [0.88][16]   | [**0.8889**][17] | [0.8764][18] | [0.897][19] | [0.8948][20] | 0.8874 ± 0.009  |
