A Hierarchical Approach to Model Web Query Interfaces for Web Source Integration

Summary: Automatically extracts Deep Web query interfaces as schema trees by combining HTML token classes with geometric layout. It reframes interface extraction as iterative integration of independently derived text and field hierarchies, improving accuracy 6.5% over prior methods. (summarized by gpt-5.6-luna on Jul 24 2026)
