[Sigia-l] Integrated online thesauri

[Web Indexing]

While people seem to recognise the value of information retrieval
thesauri in websites and intranets, few seem to use them to their full
extent, especially making them explicitly available to users. Eg, when
results of a search are provided the thesaurus context (BT, NT, RT) of
the search term is also provided, so that users can refine their search
using the other thesaurus terms. 

Has anyone worked on intranets or websites in which the thesaurus was
displayed to users? What software did you use? Did it need extra
programming? 

I find that while programs such as Microsoft SharePoint and Ultraseek
say they integrate thesauri they don't seem to go beyond simple synonym
expansion. 

Thanks,

Glenda.
