The Open World Assumption

The Open World Assumption (OWA) (as opposed to the Closed World Assumption (CWA)) means that we know our model is incomplete. Is this a good assumption to make? In short: it depends. In this video, we explore how to think about this in terms of your data.

OWL/RDF does the OWA by default, but we'll see in future videos different ways to enforce a CWA locally.
