# Fine-tuned Flair Model on CO-Fun NER Dataset

This Flair model was fine-tuned on the
[CO-Fun](https://arxiv.org/abs/2403.15322) NER Dataset using German BERT as backbone LM.

## Dataset

The [Company Outsourcing in Fund Prospectuses (CO-Fun) dataset](https://arxiv.org/abs/2403.15322) consists of
948 sentences with 5,969 named entity annotations, including 2,340 Outsourced Services, 2,024 Companies, 1,594 Locations
and 11 Software annotations.

Overall, the following named entities are annotated:

* `Auslagerung` (engl. outsourcing)
* `Unternehmen` (engl. company)
* `Ort` (engl. location)
* `Software`

## Fine-Tuning

The latest [Flair version](https://github.com/flairNLP/flair/tree/42ea3f6854eba04387c38045f160c18bdaac07dc) is used for
fine-tuning.

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

* Batch Sizes: [`16`, `8`]
* Learning Rates: [`3e-05`, `5e-05`]

More details can be found in this [repository](https://github.com/stefan-it/co-funer). All models are fine-tuned on a
[Hetzner GEX44](https://www.hetzner.com/dedicated-rootserver/matrix-gpu/) with an NVIDIA RTX 4000.

## Results

A hyper-parameter search with 5 different seeds per configuration is performed and micro F1-score on development set
is reported:

| Configuration      | Seed 1       | Seed 2       | Seed 3       | Seed 4          | Seed 5       | Average         |

| `bs16-e10-lr3e-05` | [0.9136][16] | [0.9269][17] | [0.9231][18] | [0.9251][19]    | [0.9247][20] | 0.9227 ± 0.0053 |
