	### 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.

	## Dataset Structure

	### Data Instances

	#### default

	- Size of downloaded dataset files: 21.00 MB
	- Size of the generated dataset: 20.12 MB
	- Total amount of disk used: 41.14 MB

	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,
	"type": "NN"
	}, {
	"name": "sentence",
	"pos": [3],
	"sent_id": 1,
	"type": "NN"
	}], [{
	"name": "This",
	"pos": [0],
	"sent_id": 0,
	"type": "NN"
	}]]
	}
	```

	### 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.
