ADAPTIVE EDITING IN USER INTERFACE APPLICATIONS

Systems and methods for improving automated processing of electronic media items are disclosed. In one embodiment, a computer system identifies a first set of regions of a page of an electronic media item, and a respective region type for at least one region of the first set, where the identification of the respective region type is based on one or more typographical features, historical data, and, optionally, the position and/or dimensions of the region. The computer system receives an identification by a user of a second set of regions of the page and a respective region type for at least one region of the second set, and then modifies the historical data when there is a difference between the regions and respective region types of the first set, and the regions and respective region types of the second set.
