display of a thesaurus structure based on broader/narrower
In such a display narrower terms are commonly shown
indented under the broader term which is their parent.
Each hierarchy, starting from a "top term" contains terms
from only a single facet
, so node
containing facet names do not occur within
hierachies, though they may be shown at the top of each.
A hierarchical display may contain node labels specifying
characteristics of division. An example of a hierarchical
display is shown under characteristic of division
