Robin Shing Moon Chan, Rita Sevastjanova, Mennatallah El-Assady

TL;DR
PleaSQLarify introduces a pragmatic repair approach with a visual interface for clarifying ambiguous natural language database queries, improving user control and interpretation accuracy.
Contribution
It operationalizes pragmatic repair through interpretable decision variables and a visual interface, enabling efficient clarification in natural language database querying.
Findings
Enhanced user understanding of query interpretations
Efficient ambiguity resolution through minimal interaction
Pragmatic repair improves natural language interface control
Abstract
Natural language database interfaces broaden data access, yet they remain brittle under input ambiguity. Standard approaches often collapse uncertainty into a single query, offering little support for mismatches between user intent and system interpretation. We reframe this challenge through pragmatic inference: while users economize expressions, systems operate on priors over the action space that may not align with the users'. In this view, pragmatic repair -- incremental clarification through minimal interaction -- is a natural strategy for resolving underspecification. We present \textsc{PleaSQLarify}, which operationalizes pragmatic repair by structuring interaction around interpretable decision variables that enable efficient clarification. A visual interface complements this by surfacing the action space for exploration, requesting user disambiguation, and making belief updates…
