Dataset Card for Dataset Name
This repository contains the Norwegian Summarisation Benchmark Dataset, which consists of 378 human-authored summaries from prominent Norwegian news sources across various domains. The dataset is designed to benchmark the abstractive summarisation capabilities of generative language models. NorSumm is the first manually created Norwegian news summarization datasat, created from scratch in Norwegian. The dataset consists of 378 manually generated summaries for 63 new articles. Each news article has been summarised by three native Norwegian speakers, and each generated summary has been translated to either Norwegian written form (Bokmål or Nynorsk) depending on which language the original summary has been written in.
The accompanying paper by Touileb et al. (2025) provides a comprehensive account of the data creation process and evaluates the performance of existing open large language models for Norwegian on this dataset. Additionally, it offers insights from a manual human evaluation, comparing human-authored summaries to those generated by models. The findings suggest that the dataset presents a challenging benchmark for assessing the summarisation capabilities of LLMs in Norwegian.
Source data
We used a subset of news articles from the Norwegian event extraction dataset EDEN (Touileb et al., 2024), as the source for summarisation. Due to the time-intensive nature of creating summaries, we only created summaries for the development and test splits of EDEN, comprising 30 and 33 news articles, respectively.
Dataset Description
The dataset contains pairs of articles and six generated summaries (generetaed by three individual people, in both Bokmål and Nynorsk). The news articles represen the Bokmål portion of the Norwegian Dependency treebank data NDT.
