Wikipedia link structureConfiguration: 40 iterations, damping factor 0.85, start value 0.1Languages: en, es, de, fr, it, ru, zh

Why “DBpedia”? Link structure is extracted by the DBpedia Extraction Framework

(page links dataset). The dataset is published with DBpedia IRIs.

Towards Wikidata PageRank

The DBpedia PageRank dataset has been published with Wikidata URIs since 2015-04.

Approach: Use English DBpedia PageRank and transform URIs.

Problems: Only addresses 5,789,754 entities (Wikidata 15,862,673).Language-specific bias.

Towards Wikidata PageRank

DBpedia 2016-04 provides the page links dataset with Wikidata URIs for each language edition.We merged the Wikidata URIs page links data of the ten biggest* language editions:

en , es , fr , de , zh , ru , pt , it , ar , ja

Increased coverage: 10,364,840 (Wikidata 15,862,673).

Particularity: Now we have duplicate links.

Can be leveraged – Hypothesis: reduce language-specific bias.

* Wikipedias with most users and at the same time have > 1M users
