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/.
