# Fine-tuned Flair Model on AjMC English NER Dataset (HIPE-2022)
This Flair model was fine-tuned on the
[AjMC English](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: `[3e-05, 5e-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` | [0.8565][1] | [0.8592][2] | [0.8513][3] | [0.8622][4] | [0.8534][5] | 0.8565 ± 0.0044 |
| `bs4-e10-lr5e-05` | [0.8582][6] | [0.852][7] | [0.8517][8] | [0.8544][9] | [0.842][10] | 0.8517 ± 0.006 |
| `bs8-e10-lr5e-05` | [**0.8412**][11] | [0.8369][12] | [0.853][13] | [0.8392][14] | [0.85][15] | 0.8441 ± 0.007 |
| `bs8-e10-lr3e-05` | [0.8483][16] | [0.8431][17] | [0.8443][18] | [0.8486][19] | [0.8359][20] | 0.844 ± 0.0052 |
