12. A machine-based method for use in a conversion of data from a first form associated with a data source to a second form for use by a target data system, comprising the steps of: receiving content associated with said data source; obtaining first information from said content for use in said conversion; first using said first information to obtain second information from a location, external to said content, for use in said conversion; and second using said first information and said second information in said conversion of said content from said first form to said second form wherein said step of second using is executed by a machine having access to a first semantic metadata model including a classification structure for a subject matter under consideration and associated conversion rules, and a number of sets of frame rules, separate from said semantic metadata model, for use in disambiguating terms based on specific subject matter contexts within said subject matter under consideration, and said step of second using comprises selecting one of said sets of frame rules.

A method as set forth in claim 12 , wherein said first information identifies a subject matter context of said content and said step of first using comprises accessing conversion rules specific to said subject matter context.
