## 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)

### 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    |
