-# Dataset Card for "dawiki_categories"
+# Danish Wikipedia Categories
 
-[More Information needed](https://github.com/huggingface/datasets/blob/main/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)
+The dataset was created entirely from the [last Danish Wikipedia dump](https://dumps.wikimedia.org/dawiki/20240101/)
+by traversing the category hierarchy in the [categorylinks table](https://www.mediawiki.org/wiki/Manual:Categorylinks_table).
+
+All categories that were one level bellow the topcategories, and which had more than 30 articles assigned to them were selected.
+In order to see whether an article belongs to a certain category I checked, whether the article was connected to the category in the directed graph of the category hierarchy.
+If the length of the path between the article and a category was less than or equal to 5 edges (arbitrary choice, but I found it to work well),
+the category was assigned to the article.
+
+Note that this is a multilabel classification task.
+Its purpose is to train sentence transformers for the [DFM project](https://centre-for-humanities-computing.github.io/danish-foundation-models/) using a technique similar to [SetFit](https://arxiv.org/abs/2209.11055).
