8. A GUI evaluation method for evaluating an evaluation target screen included in the evaluation system, comprising: storing, as screen information in a screen information recording section, information on text and input/output components as elements on the evaluation target screen; specifying a group of elements, and in specifying the group of elements, referring to the screen information stored in the screen information recording section to specify a small group, the small group specification being based on a set of i) an input/output component and ii) an element close to the input/output component, and specifying a medium group, the medium group specification being based on a set of a small group which is specified by the small group, and one of the group consisting of i) another small group, ii) text close to the small group, iii) the other small group and the text; and evaluating appropriateness of a layout of elements and input/output components in the small group included in the medium group based on a presence or an absence of elements in the medium group containing the specified element and a relationship between the position of an input/output component and the position of an element close to the input/output component, wherein upon evaluating the layout of elements, determining whether text display corresponding to the input/output component is included in respective medium groups and respective small groups.
