US Patent 7228314 Apparatus and method for controlling user interface

The user describes in advance conflict process rules, which indicate descriptions for avoiding conflicts that occur between setup data, in a conflict process rule description file (301). An inference engine (302) refers to this conflict process rule description file (301) and generates complementary rules indicating complementary conflict avoidance descriptions. The complementary rules are implemented by generating inverse logic rules of given descriptions for a function, which are described to allow inference by analogy.
