Editing Application For Synthesized eBooks

A software application to assist human operators to efficiently correct errors in electronic books (eBooks) is described. The application presents the operator with a graphical user interface (GUI) including a page image of a source document (e.g., a printed publication) alongside a rendition of structured content extracted from the page image. The operator can make a structural change as well as a low-level text change in the rendition by issuing an editing command through the GUI. The editing command is sent to a server hosting an intermediate document for the source document and the page image. The server modifies the intermediate document by applying the editing command, and transmits to the application an updated rendition generated based on the modified intermediate document. The application displays the updated rendition to reflect the change made in response to the editing command.
