Understanding Web Query Interfaces: Best-Effort Parsing with Hidden Syntax

Summary: Models web query forms as a visual language with a hidden, shared syntax guiding interface construction. Introduces a 2P grammar and best-effort parser to derive this syntax and extract query conditions, achieving ~85% accuracy across random sources. (summarized by gpt-5-nano on Feb 09 2026)
