Title: Empowering Student Query Debugging: Feedback for Aggregate Queries via Provenance Summarization

Abstract:
Data provenance contains valuable information about the data involved in a query and the process it underwent to produce the output. Despite extensive research on data provenance generation and refinement, its potential in query debugging has not been fully exploited. Observing students’ struggle in writing aggregate queries, we adapted a provenance summarization technique for pedagogical purposes and introduced a novel feedback approach to assist students in query debugging. Our user study confirmed the effectiveness and helpfulness of this technique.
