Abstract: This paper finds the essential differences between objects in terms of available attributes in a knowledge representation system (KR-system) where neither condition nor decision attributes are distinguished. We find these differences by using the concepts of "almost indiscernibility relation" and "approximate decision logic (ADL)" language. Here, an information system has been considered where attribute values are not always quantitative, rather subjective having vague or imprecise meanings.

Keywords: Almost; indiscernibility; relation; ADL-language; [alpha]-reduct; [alpha]-core (search for similar items in EconPapers)
