# 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 Tiny 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         |
|-------------------|--------------|-----------------|--------------|--------------|--------------|-----------------|

| `bs8-e10-lr5e-05` | [0.5301][6]  | [0.468][7]      | [0.525][8]   | [0.4989][9]  | [0.4707][10] | 0.4985 ± 0.0292 |

| `bs8-e10-lr3e-05` | [0.4402][16] | [0.3531][17]    | [0.4141][18] | [0.3808][19] | [0.4073][20] | 0.3991 ± 0.0333 |
