-### Dataset
+### Dataset Description
 The dataset consists of over 100K figure+caption pairs from the [astroexplorer.org](https://www.astroexplorer.org/) from recent open access astronomy papers. More details to come.
+```
+Dataset({
+    features: ['image', 'UUID', 'Image ID', 'Paper DOI', 'Paper Title', 'Image Caption', 'Image Authors', 'References DOIs', 'Citing DOIs'],
+    num_rows: 94233
+})
+```
+(test set  to be released in November 2026)
+- `images` are stored as PIL PNG objects.
+- `Image Caption` are English language text.
+- `UUID`, `Image ID`, `Paper DOI`, `Paper Title` are metadata.
+
+A more complete descriptions of the dataset can be found on the WASP2026 website [here](https://ui.adsabs.harvard.edu/WIESP/2026/shared_task_labels).
 
 ### Task Description
 The goal of the task is single-class classification.
 The inputs are pairs of figures, a figure and a caption, or a pair of captions.
-The possible classes are:
-- `"same paper"`
-- `"different paper but related"` (cited/citing)
-- `"unrelated"`
-- `"same figure"` (only for figure+caption pairs)
+The possible output classes are:
+- `same paper`
+- `related papers` (references or citing)
+- `unrelated papers` (neither references nor citing)
+- `same figure` (only for figure+caption pairs)
+
+The challenge is being evaluated on Kaggle [here](https://www.kaggle.com/competitions/astroclimb/overview).
