(i.e., concepts with erroneous synonymity) in
the Unified Medical Language System (UMLS). The
idea is to identify the inconsistencies by comparing the
semantic groups of hierarchically-related concepts using
Answer Set Programming. With this method, we
identified several inconsistent concepts in UMLS and
discovered an interesting semantic pattern along hierarchies,
which seems associated with wrong synonymy.},
