CO-Fun: A German Dataset on Company Outsourcing in Fund Prospectuses for Named Entity Recognition and Relation Extraction
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). Furthermore, state-of-the-art deep learning models were trained on this dataset to recognize entities and extract relations. This repository is the anonymized version of the dataset, along with guidelines and the code used for model training. Additionally, this dataset is also hosted on Zenodo.
In the following the content of each file is explained:
- CO-Fun-1.0-anonymized.jsonl file contains the raw data of CO-Fun consists of records formatted in JSON. Each entry has the annotated text which is present in form of HTML. The annotation for each named entity in the text are specified with span tags. Below you can find an exmple of an entry in raw data:
