Abstract
An underlying schema is discovered for an HTML document or a set of HTML documents, authored in various styles. Prior domain knowledge regarding punctuation, keywords, synonyms and HTML tags is used to 1) break a document up into separate objects, 2) identify the objects corresponding to keywords, 3) regroup objects: into hierarchical layers of abstraction, 4) logically order objects at the same level of abstraction, and 5) finally remove any non-keyword related information from the document's discovered schematic structure. The discovered schema supports structural queries from search engines that locate data that are more semantically related to the requested information than data located by simple keyword searching.
