+# Dataset Card for `cranfield`
+
+The `cranfield` dataset, provided by the [ir-datasets](https://ir-datasets.com/) package.
+For more information about the dataset, see the [documentation](https://ir-datasets.com/cranfield#cranfield).
+
+# Data
+
+This dataset provides:
+ - `docs` (documents, i.e., the corpus); count=1,400
+ - `queries` (i.e., topics); count=225
+ - `qrels`: (relevance assessments); count=1,837
+
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+docs = load_dataset('irds/cranfield', 'docs')
+for record in docs:
+    record # {'doc_id': ..., 'title': ..., 'text': ..., 'author': ..., 'bib': ...}
+
+queries = load_dataset('irds/cranfield', 'queries')
+for record in queries:
+    record # {'query_id': ..., 'text': ...}
+
+qrels = load_dataset('irds/cranfield', '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.
