Evaluating Search System Explainability with Psychometrics and Crowdsourcing

no code implementations17 Oct 2022 Catherine Chen, Carsten Eickhoff

In this paper, we use psychometrics and crowdsourcing to identify human-centered factors of explainability in Web search systems and introduce SSE (Search System Explainability), an evaluation metric for explainable IR (XIR) search systems.
