MODIFYING AN APPEARANCE OF A GUI TO IMPROVE GUI USABILITY

A method, system, and/or computer program product modifies a graphical user interface (GUI) for an application to improve usability of the current GUI. One or more processors build a graphical user interface (GUI) neural knowledge base to capture GUIs used by multiple software applications based on a function, semantics, and context of captured GUIs. The processor(s) identify a current GUI that is utilized by a current software application, and match the current GUI to captured GUIs that have a same function, semantics, and context as the current GUI. The processor(s) identify a top-k active field used by the captured GUIs, and match a function of a current active field to a function of the top-k active field. If the visual appearance of the current active field does not match the visual appearance of the top-k active field, the processor(s) replace the current active field with the top-k active field.
