+# Dataset Card for `nfcorpus/train`
+
+The `nfcorpus/train` dataset, provided by the [ir-datasets](https://ir-datasets.com/) package.
+For more information about the dataset, see the [documentation](https://ir-datasets.com/nfcorpus#nfcorpus/train).
+
+# Data
+
+This dataset provides:
+ - `queries` (i.e., topics); count=2,594
+ - `qrels`: (relevance assessments); count=139,350
+
+ - For `docs`, use [`irds/nfcorpus`](https://huggingface.co/datasets/irds/nfcorpus)
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+queries = load_dataset('irds/nfcorpus_train', 'queries')
+for record in queries:
+    record # {'query_id': ..., 'title': ..., 'all': ...}
+
+qrels = load_dataset('irds/nfcorpus_train', 'qrels')
+for record in qrels:
+    record # {'query_id': ..., 'doc_id': ..., 'relevance': ..., 'iteration': ...}
+
+```
+
+Note that calling `load_dataset` will download the dataset (or provide access instructions when it's not public) and make a copy of the
+data in 🤗 Dataset format.
