Exploiting Content Redundancy for Web Information Extraction

Summary: Exploits content redundancy on template-based sites to bootstrap a seed database and extract matching attribute values from new pages. Presents a template-aware similarity metric and an Apriori-style search over fixed attribute positions to filter noise, with experiments on real web data. (summarized by gpt-5-nano on Feb 09 2026)
