	## Dataset Description

	- Repository: [AIDA CoNLL-YAGO Wikidata repository](https://github.com/cyanic-selkie/aida-conll-yago-wikidata)

	### Dataset Summary

	The AIDA CoNLL-YAGO Wikidata dataset is the same as the original [AIDA CoNLL-YAGO](https://www.mpi-inf.mpg.de/departments/databases-and-information-systems/research/ambiverse-nlu/aida/downloads) dataset, but with Wikidata QIDs instead of Wikipedia titles as entity identifiers. They are automatically generated (with a few manual corrections) from Wikidata and Wikipedia dumps (March 1, 2023).

	The code for generating the dataset can be found [here](https://github.com/cyanic-selkie/aida-conll-yago-wikidata).

	### Supported Tasks

	- `named-entity-recognition`: The dataset can be used to train a model for Named Entity Recognition.
	- `named-entity-linking`: The dataset can be used to train a model for Named Entity Linking.

	### Languages

	The text in the dataset is in English. The associated BCP-47 code is `en`.

	## Dataset Structure

	### Data Instances

	A typical data point represents a document (news article).

	The `text` field contains the original text in an NFC normalized, UTF-8 encoded string.

	The `entities` field contains a list of entities, each represented by a struct with the inclusive starting byte `start` field, exclusive ending byte `end` field, a nullable `qid` field, and a nullable `pageid` field.

	Additionally, each document has a unique `document_id` field.

	An example from the AIDA CoNLL-YAGO Wikidata test set looks as follows:

	```

	### Data Fields

	- `document_id`: an integer that uniquely identifies the document this sentence belongs to
	- `sentence_index`: an integer that uniquely identifies the position of the sentence in its original document
	- `text`: an NFC normalized, UTF-8 encoded string representing the sentence
	- `entities`: a list of structs representing entities, each entity has:
	- `start`: an integer representing the inclusive starting UTF-8 code point of the entity
	- `end`: an integer representing the exclusive ending UTF-8 code point of the entity
	- `tag`: a string representing the entity type (PER, LOC, ORG or MISC)
	- `qid`: an integer representing the Wikidata QID this entity refers to; it can be null if the entity didn't exist in Wikidata at the time of the creation of the original dataset
	- `pageid`: an integer representing the English Wikipedia's pageID this entity refers to; it can be null if the entity didn't exist in Wikipedia at the time of the creation of the original dataset
	- `title`: an NFC normalized, UTF-8 encoded string representing the English Wikipedia's title this entity refers to; it can be null if the entity didn't exist in Wikipedia at the time of the creation of the original dataset

	### Data Splits

	The data is split into training, validation and test sets; all of the sentences belonging to an article are in the same split. The final split sizes are as follows:

	\| \| Train \| Validation \| Test \|
	\| :----- \| :------: \| :-----: \| :----: \|
	\| AIDA CoNLL-YAGO Wikidata - documents \| 946 \| 216 \| 231 \|
	\| AIDA CoNLL-YAGO Wikidata - entities \| 23,374 \| 5,912 \| 5,608 \|
