An introduction to querying linked data, using the SPARQL query language and the free knowledge base Wikidata. Which films starred more than one future head of government? What’s the largest city with a female mayor? And when did women finally outnumber Johns in the House of Commons? These are the kinds of questions that **linked data** can answer. This workshop will give an introduction to the SPARQL query language, showing how it can be used to answer these and other questions, using the free knowledge base **Wikidata** as the data source.
