-Note: this example shows a quirk(?) of the Wiki data. The French Wikipedia page [The World's Finest Assassin Gets Reincarnated in Another World as an Aristocrat](https://fr.wikipedia.org/wiki/The_World%27s_Finest_Assassin_Gets_Reincarnated_in_Another_World_as_an_Aristocrat) used the English title as its translation. While this could be disadvantageous for direct translation training, it also provides insights into how native speakers might call this entity instead of the literal translation

+## Dataset Structure
+
+Each language has its own subset (aka config), which means you only have to download the languages you need with `datasets>=2.14.0`
+
+Each subset has these fields:
+- wikidata_id
+- lastrevid
+- label
+
+
+## Dataset Creation
+
+#### Data Collection and Processing
+
+- Filtered for item entities only
+- Ignored the descriptions as those texts are not very parallel
+
+## Bias, Risks, and Limitations
+
+- Might be slightly outdated (2022)
+- Popular languages have more entries
+- Labels are not guaranteed to be literal translations (see examples above)
