Abstract: A system comprising: an input receiving an input document comprising text data and graphical data distinguishing hierarchically first and second portion of the text data; a display displaying said input document; a user interface allowing a user to add, in superposition with the displayed input document, boundary markers visually bounding said first and second text portions; and a processor arranged for, using the boundary markers added to the displayed input document, training a layout data analysis model to determine, in a further input document having further text data, if graphical data distinguishes hierarchically first and second portions of the further text data to display automatically boundary markers visually bounding said first and second portions of said further text data; the user interface allowing said user to correct the boundary markers displayed by the layout analysis model and the processor training the layout data analysis model using the corrected boundary markers.
