kgdata.wikidata.datasets.entity_redirections

Functions

entity_redirections()	Wikidata entity redirections.
extract_id(row)
postprocess_groupby(record)

entity_redirections() → Dataset[Tuple[str, str]]

Wikidata entity redirections. It combines two datasets: page_ids and entity_redirection_dump. The first one contains mapping from page_id => entity_id (can be old id). The second one contains mapping from page_id => final entity_id.

We did a join between two datasets based on page_id so we can get the mapping from old entity_id to the final entity_id.

Finally, we check if the final entity id is in the entity_ids dataset. If not, we remove the mapping.

Returns:

Dataset[tuple[str, str]]

Return type:

Dataset[Tuple[str, str]]

extract_id(row: list) → tuple[str, str] | None

Parameters:

Return type:

tuple[str, str] | None
