    • An attribute-value system is a basic knowledge representation framework comprising a table with columns designating "attributes" (also known as "properties", "predicates," "features," "dimensions," "characteristics" or "independent variables" depending on the context) and rows designating "objects" (also known as "entities," "instances," "exemplars," "elements" or "dependent variables"). Each table cell therefore designates the value (also known as "state") of a particular attribute of a particular object.

Some authors use feature as a synonym for attribute (e.g., in feature-subset selection).
