A computer-implemented method comprising: obtaining a digital representation of a first version of a Graphical User Interface, GUI, wherein the GUI comprises a GUI element, wherein the digital representation of the first version of the GUI comprises a first digital file; obtaining a digital representation of a second version of the GUI, wherein the digital representation of the second version of the GUI comprises a second digital file; obtaining an indication of an element (647a, 647b) from an acquisition process, wherein the acquisition process is operated on the second version of the GUI, wherein the acquisition process comprises identifying the element (647a, 647b) in the second version of the GUI using a representation of the GUI element in the first version of the GUI, wherein the representation of the GUI element comprises a plurality of alternative representations of the GUI element in the first version of the GUI, wherein the indication indicates that the element (647a, 647b) is estimated to correspond to the GUI element in the first version of the GUI; displaying, in parallel, the first version of the GUI and the second version of the GUI, wherein said displaying comprises: presenting a first visual indication of the GUI element in the first version of the GUI; and presenting a second visual indication of the element (647a, 647b) in the second version of the GUI; obtaining user input based on the first and second visual indications, wherein the user input is indicative of whether the element (647a, 647b) that is indicated by the second visual indication corresponds to the GUI element that is indicated by the first visual indication; and updating the acquisition process based on the user input, wherein said updating the acquisition process comprises: updating the representation of the GUI element by removing a subset of the plurality of alternative representations of the GUI from the representation of the GUI element, wherein the subset comprises at least one alternative representation from the plurality of alternative representations that does not conform with the user input. obtaining a digital representation of a first version of a Graphical User Interface, GUI, wherein the GUI comprises a GUI element, wherein the digital representation of the first version of the GUI comprises a first digital file; obtaining a digital representation of a second version of the GUI, wherein the digital representation of the second version of the GUI comprises a second digital file; obtaining an indication of an element (647a, 647b) from an acquisition process, wherein the acquisition process is operated on the second version of the GUI, wherein the acquisition process comprises identifying the element (647a, 647b) in the second version of the GUI using a representation of the GUI element in the first version of the GUI, wherein the representation of the GUI element comprises a plurality of alternative representations of the GUI element in the first version of the GUI, wherein the indication indicates that the element (647a, 647b) is estimated to correspond to the GUI element in the first version of the GUI; displaying, in parallel, the first version of the GUI and the second version of the GUI, wherein said displaying comprises: presenting a first visual indication of the GUI element in the first version of the GUI; and presenting a second visual indication of the element (647a, 647b) in the second version of the GUI; presenting a first visual indication of the GUI element in the first version of the GUI; and presenting a second visual indication of the element (647a, 647b) in the second version of the GUI; obtaining user input based on the first and second visual indications, wherein the user input is indicative of whether the element (647a, 647b) that is indicated by the second visual indication corresponds to the GUI element that is indicated by the first visual indication; and updating the acquisition process based on the user input, wherein said updating the acquisition process comprises: updating the representation of the GUI element by removing a subset of the plurality of alternative representations of the GUI from the representation of the GUI element, wherein the subset comprises at least one alternative representation from the plurality of alternative representations that does not conform with the user input.
