I can understand this. Would s/scope/application scope improve the situation?

In fact I expect that these cases would be quite frequent. If a KOS designer agreed that a mapping link between two concepts in her KOS fit her intent when creating the KOS, she would have created it as a standard semantic relationship then, wouldn't she?
