# Dataset Card for SmartData Corpus

## Dataset Description

- **Repository:** [https://github.com/dfki-nlp/smartdata-corpus](https://github.com/dfki-nlp/smartdata-corpus)
- **Paper:** [A German Corpus for Fine-Grained Named Entity Recognition and Relation Extraction of Traffic and Industry Events](https://www.dfki.de/web/forschung/projekte-publikationen/publikation/9427/)

### Dataset Summary

SmartData Corpus is a German-language dataset which is human-annotated with entity types and a set of 15 traffic- and 
industry-related n-ary relations and events, such as accidents, traffic jams, acquisitions, and strikes. 
The corpus consists of newswire texts, Twitter messages, and traffic reports from radio stations, police and 
railway companies.

This version of the dataset loader provides configurations for:

- Named Entity Recognition (`ner`): NER tags use the `BIO` tagging scheme
- Relation Extraction (`re`): n-ary Relation Extraction
- Event Extraction (`ee`): formatted similar to https://github.com/nlpcl-lab/ace2005-preprocessing?tab=readme-ov-file#format

For more details see https://github.com/dfki-nlp/smartdata-corpus and https://www.dfki.de/web/forschung/projekte-publikationen/publikation/9427/.

### Supported Tasks and Leaderboards
