Algorithms play a key role nowadays in many technological systems that control or affect various aspects of our lives. Decisions made by those systems are often driven by data and their processing, both of which are typically shielded from end users that are affected by them. For this reason, various recent regulations require organisations to explain and justify automated decisions affecting their data subjects.
Provenance, and its standard PROV, which describes how a piece of information or data was created and what influenced its production, provides the technological capability to explain complex decision pipelines and their outcomes.
On this website, we present a loan scenario in which we explored ways to explain various aspects of automated decisions to end users from the recorded provenance of those decisions.
