The following analysis is done on Wikidata as a means to understand more about Wikidata itself. This includes what kind of subjects, properties, objects etc does it contain the most, the type of triples it contains, how much of it refers to wiki or non-wiki objects etc. The Analysis was done on Wikidata snapshot 20210614 using Python in Jupyter Notebook. Other packages used are: Spark, RDFLib, SPARQLWrapper, andas. Parts of some analysis collected data with SPARQL from WDQS endpoint, which fetches the latest data (to easily get labels and data types of literals for example). So a small difference is sometimes found with the snapshot and latest data.

Items

How many different things does Wikidata talk about? It's a very high-level overview question and answered based on the context from Wikidata. For example, all triples under Q42 context can be found here: Q42 dump. Top 20 items are shown in the table below.
