Unfortunately, these terms, as well as "facet", "array", "subfacet" and
others have been used in the past with various different and overlapping
meanings, often without any clear or precise definition. As terminology
specialists we have been remarkably imprecise in our usage of
The definitions on the site at
<http://www.willpowerinfo.co.uk/glossary.htm> are an attempt to bring
some order into this situation by recognising the different concepts
that we deal with and suggesting distinctive labels for each.
Personally I would have liked to have different names for the two types
of node labels specified in the glossary, but others thought that they
should both be called "node labels" while recognising the existence of
two types with very different contents and properties.

Yes, I too would be very interested to know whether people think that
the distinctions made in our glossary are clear, helpful and acceptable.
If not, alternative suggestions are welcome . . .

I'm not sure what you mean by "facet indicator labels" and "notation
labels", but generally thesaurus software is very poor at handling node
labels properly. At best they may be given an attribute that
distinguishes them from thesaurus terms, but the relationship between
them and the terms above and below them is generally just the standard
BT/NT; really these are just labels interposed in order to group terms
and should not themselves participate in the hierarchical structure.
Thesaurus software also cannot generally place these labels correctly in
an alphabetical list if they are written in parentheses or angle
brackets, as they conventionally are - they then sort at the start of
