Subject: Re: general type of controlled vocabulary

I have just started to study this so I have not yet read some of the
central literature (e.g. Hodges) on this topic. But I have discussed
this at length with faculty & other doctoral students here at Univ North

That caveat aside, I rather like the typology in the NISO Z39.19
standard -- Guidelines for the Construction, Format and Management of
Monolingual Controlled Vocabularies.  They have 4 types and a list of
criteria for them:

    Ambiguity Control
Synonym ring
    synonym control
    Ambiguity Control
    synonym control
    Hierarchical relationships
    Ambiguity Control
    synonym control
    Hierarchical relationships
    Associative relationships

And I found the definitions for the different criteria well developed
and easy to understand.


Hope this helps,
