Wordnet/SUMO/SubjectiveAssessmentAttribute

(documentation SubjectiveAssessmentAttribute EnglishLanguage "The Class of NormativeAttributes which lack an objective criterion for their attribution, i.e. the attribution of these Attributes varies from subject to subject and even with respect to the  same subject over time. This Class is, generally speaking, only used when mapping external knowledge sources to the SUMO. If a term from such a knowledge source seems to lack objective criteria for its attribution, it is assigned to  this Class.")
