Wikidata is a project of the Wikimedia Foundation (WMF), the organisation behind Wikipedia. It has the aim of developing a free and open knowledge base of structured data from Wikipedia, as well as WMF’s other projects and beyond. Wikidata classifies over 100 million items (such as people, places, objects and works) into a highly extensible ontology, which can then be linked to other Wikidata items or external datasets. Powerful query tools allow visualisation of the data as maps, timelines and a variety of charts and tables, or the data can be exported in a variety of structured formats. This talk will introduce Wikidata and explain how data is structured, modeled and referenced. It will demonstrate how data is edited and the various tools used to wrangle data. The talk will also look at how wikidata is used by Wikipedia itself and also communities who need an open, crowd-sourced, referenced database to support their work. The talk will also demonstrate how wikidata can be queried using SPARQL, the Wikidata API and other tools and how it can be visualised. YouTube:
