# Dataset Card for Dataset Name

## Dataset Description

This dataset contains Key Figures with their properties from german tax acts. The dataset is annotated by tax experts and consists of 85 annotated paragraphs from 14 different German tax acts with 157 annotated tax key figures.
The annotation was performed based on a developed universally applicable annotation schema and a semantic model for key figures and their properties in legal texts.
More details about the schema and the semantic model can be found in our [Paper](https://ceur-ws.org/Vol-3441/paper7.pdf). There we also provide a knowledge graph populated from these annotated paragraphs.
