## Dataset Structure

```
{
    "title": "Title of the page",
    "qid": "QID of the corresponding Wikidata entity",
    "words": ["tokens"],
    "wikipedia": ["Wikipedia description of each entity"],
    "labels": ["NER labels"],
    "titles": ["Wikipedia title of each entity"],
    "qids": ["QID of each entity"],
}
```

The `words` field contains the article’s text splitted on white-spaces. The other fields are list with same length as `words` and contains data only when the respective token in `words` is the __start of an entity__. For instance, if the _i-th_ token in `words` is an entity, then the _i-th_ element of `wikipedia` contains a description, extracted from Wikipedia, of this entity. The same applies for the other fields. If the entity spans multiple words, then only the index of the first words contains data.

The only exception is the `labels` field, which is used to delimit entities. It uses the IOB encoding: if the token is not part of an entity, the label is `"O"`; if it is the first word of a multi-word entity, the label is `"B"`; otherwise the label is `"I"`.
