Confusion is also defined (§3.3) for hierarchies whose nodes are associated with predicates (called variables in the paper) in addition to hierarchies whose nodes are associated with values of a variable (item 1). An element set whose values are ordered by a < ("less than") relation. A hierarchy groups E into smaller sets of alike symbolic values. 3.3 Confusion between variables (not values) that form a hierarchy distance on hierarchies of symbolic values (to measure closeness between hierarchical • Confusions and similarity functions for values in different ontologies can be defined as The notions of hierarchy and hierarchical variable make possible to measure the confusion when a value is used instead of another.	./cache/work_i6rnbhcflbchhbsvdprmugxlxy.pdf	./txt/work_i6rnbhcflbchhbsvdprmugxlxy.txt
