1. A system, comprising: a mapping logic, embodied as machine-executable instructions stored on a non-transitory machine readable medium, to create a mapping between an application object and an ontology data element, where the ontology describes a structure of application objects in an application; and an information extraction (IE) logic, embodied as machine-executable instructions stored on a non-transitory machine readable medium: to access the mapping logic to identify an one or more ontology data elements, the identification being based, at least in part, on the mapping between the application object that characterizes an application data element and the ontology data element, application data elements being stored in one or more application data repositories belonging to an enterprise; to locate the ontology data element in documents stored in the one or more data repositories; and to create a link between respective documents from which an ontology data element is selected and the respective applications having an application object mapped to the ontology data element located in the respective documents, where the link is appended to the document for use in future processing.
