US Patent 7613996 Enabling selection of an inferred schema part

Systems and/or methods (“tools”) are described that convert or present conversion problems for electronic documents. The tools may convert a generally unstructured electronic document to a generally structured electronic document using non-visual textual and layout information of the unstructured document. The tools can also present possible problems with this or other types of conversion. And the tools can enable a user to alter an electronic document's schema without altering its visual layout.
