Fine-tuned Flair Model on CO-Fun NER Dataset
This Flair model was fine-tuned on the CO-Fun NER Dataset using German BERT as backbone LM.
Dataset
The Company Outsourcing in Fund Prospectuses (CO-Fun) dataset 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 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. All models are fine-tuned on a Hetzner GEX44 with an NVIDIA RTX 4000.
