+### [Dataset Summary](#dataset-summary)
+
+Multiple entities in a document generally exhibit complex inter-sentence relations, and cannot be well handled by existing relation extraction (RE) methods that typically focus on extracting intra-sentence relations for single entity pairs. In order to accelerate the research on document-level RE, we introduce DocRED, a new dataset constructed from Wikipedia and Wikidata with three features:
+    - DocRED annotates both named entities and relations, and is the largest human-annotated dataset for document-level RE from plain text.
+    - DocRED requires reading multiple sentences in a document to extract entities and infer their relations by synthesizing all information of the document.
+    - Along with the human-annotated data, we also offer large-scale distantly supervised data, which enables DocRED to be adopted for both supervised and weakly supervised scenarios.

+An example of 'train_annotated' looks as follows.
+```
+{
+    "labels": {
+        "evidence": [[0]],
+        "head": [0],
+        "relation_id": ["P1"],
+        "relation_text": ["is_a"],
+        "tail": [0]
+    },
+    "sents": [["This", "is", "a", "sentence"], ["This", "is", "another", "sentence"]],
+    "title": "Title of the document",
+    "vertexSet": [[{
+        "name": "sentence",
+        "pos": [3],
+        "sent_id": 0,

+    }, {
+        "name": "sentence",
+        "pos": [3],
+        "sent_id": 1,
+        "type": "NN"
+    }], [{

+        "sent_id": 0,
+        "type": "NN"
+    }]]
+}
+```
+
+### [Data Fields](#data-fields)
+
+The data fields are the same among all splits.
+
+#### default
+- `title`: a `string` feature.
+- `sents`: a dictionary feature containing:
+  - `feature`: a `string` feature.
+- `name`: a `string` feature.
+- `sent_id`: a `int32` feature.
+- `pos`: a `list` of `int32` features.
+- `type`: a `string` feature.
+- `labels`: a dictionary feature containing:
+  - `head`: a `int32` feature.
+  - `tail`: a `int32` feature.
+  - `relation_id`: a `string` feature.
+  - `relation_text`: a `string` feature.
+  - `evidence`: a `list` of `int32` features.
