1. A method for simplifying the presentation of a visually complex semantic model comprising: within a presentation area of a graphical modeling application running on a computing device, visually displaying on a display screen a visually complex semantic model, comprising a first quantity of visual objects and a first quantity of associations between the objects, wherein each visual object is visually connected to another of the objects by at least one association, wherein each association visually represents a relationship between the objects shown on the display screen; the graphical modeling application running on the computing device receiving a user-selected command to simplify a presentation of the displayed visually complex semantic model by a model simplification tool determining an association status for each object representation in the visually complex semantic model according to a plurality of simplification rules, wherein the association status determined for each of the objects is one of an autonomous object, a containment object, and a subordinate object; and transforming the presentation of the visually complex semantic model into a different visual representation referred to as a simplified semantic model, which is visually displayed in the presentation area, wherein the simplified semantic model comprises a second quantity of objects and a second quantity of simplified associations, wherein each displayed object of the second quantity is connected to another object of the second quantity by at least one of the simplified associations, wherein at least a portion of the objects of the second quantity are containment objects comprising at least one subordinate object visually nested within the containment object, wherein the second quantity of objects is less than the first quantity of objects, wherein the second quantity of associations is less than the first quantity of associations, and wherein each object of the visually complex semantic model is represented within the simplified semantic model by an object of the second quantity or by at least one subordinate object, wherein the simplified semantic model is rendered within the presentation area of the graphical modeling application.
