In this talk, we will discuss how knowledge graphs can support reasoning (also known as inference), how to describe information required by reasoning in a form of rules, and how to manage the inferred facts across the data lifecycle. This capability is important for many applications such regulatory compliance. For example, if we captured information about our data sources in a knowledge graph and knew that one of the sources stored data about EU residents, we could infer that the data source and a company that owns it are subject to GDPR regulations.
Topics we will cover in this talk are:
- Syntax for defining rules that will support inferences
- Differences between rules that check for data quality/validity and rules that infer new facts
- Testing and debugging rules
- Static (batch) inferencing vs. dynamic, query time inferencing
- Performance considerations for using inferencing
- Uncertainty and inferencing
