The dataset generation failed because of a cast error
Error code:   DatasetGenerationCastError
Exception:    DatasetGenerationCastError
Message:      An error occurred while generating the dataset

All the data files must have the same columns, but at some point there are 2 new columns ({'DET', 'Die'}) and 2 missing columns ({'PROPN', '•'}).

This happened while the csv dataset builder was generating data using

hf://datasets/stefan-it/co-funer/dev.tsv (at revision 2b7ab02b5b7ad35aa13c26e3e6da306f16ee4049)

Please either edit the data files to have matching columns, or separate them into different configurations (see docs at https://hf.co/docs/hub/datasets-manual-configuration#multiple-configurations)

CO-Fun: A German Dataset on Company Outsourcing in Fund Prospectuses for Named Entity Recognition and Relation Extraction

This inofficial dataset repository provides a CoNLL-like version of the CO-Fun NER dataset, that was proposed in the CO-Fun paper (https://arxiv.org/abs/2403.15322):

The process of cyber mapping gives insights in relationships among financial entities and service providers. Centered around the outsourcing practices of companies within fund prospectuses in Germany, we introduce a dataset specifically designed for named entity recognition and relation extraction tasks. The labeling process on 948 sentences was carried out by three experts which yields to 5,969 annotations for four entity types (Outsourcing, Company, Location and Software) and 4,102 relation annotations (Outsourcing-Company, Company-Location). State-of-the-art deep learning models were trained to recognize entities and extract relations showing first promising results.

Preprocessing

The notebook Export-To-CoNLL.ipynb performs the necessary steps to create a CoNLL-like version of the CO-Fun dataset, that could easily be used for fine-tuning NER models.

Additionally, the FlairDatasetTest.ipynb notebooks loads the dataset with the Flair dataset loader and checks, if the number of parsed sentences is correct and identical to the number of sentences reported in the official CO-Fun paper.

Named Entites

The CO-Fun dataset provides annotations for the following Named Entities:

  • Auslagerung (engl. outsourcing)
  • Unternehmen (engl. company)
  • Ort (engl. location)
  • Software

Example: Load Dataset with Flair library

The notebooks FlairDatasetExample.ipynb shows how to load the dataset with the awesome Flair library.

Changelog

  • 25.03.2024: Initial version of the preprocessed CO-Fun NER dataset is released.

Licence

The original CO-Fun dataset is released under MIT license. Thus, this preprocessed version is also licenced under MIT.
