DEXTER: Large-Scale Discovery and Extraction of Product Specifications on the Web

Summary: DEXTER locates product-spec pages with a focused crawler (queries + backlinks) and detects specs via a supervised HTML-fragment classifier. Extraction uses two wrappers: (i) a domain-independent unsupervised wrapper from shared structure, and (ii) a noisy-annotator hybrid; results on 1.46M pages show F≈0.9, precision 0.92, recall 0.95.
