The SphereSearch Engine for Unified Ranked Retrieval of Heterogeneous XML and Web Documents

Summary: SphereSearch: unified ranked retrieval across heterogeneous XML and Web data. Supports vague structure and text criteria, plus concept- and link-aware ranking via IR statistics and ontologies; HTML/PDF pages convert to XML with semantic tagging, enabling rich queries on a richly tagged encyclopedia.
