Fine-tuned Flair Model on CO-Fun NER Dataset

This Flair model was fine-tuned on the CO-Fun NER Dataset using German DBMDZ 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: [8, 16]
• Learning Rates: [5e-05, 3e-05]

More details can be found in this repository. All models are fine-tuned on a Hetzner GEX44 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:
