Object-level Vertical Search

Summary: Introduce object-level vertical search: extract and integrate structured object records from webpages and databases to enable entity-centric, domain-specific retrieval instead of document-level ranking. Outline techniques for object extraction, integration and combined relevance+popularity ranking; implemented in Libra Academic Search and Windows Live Product Search.
