Custom Online Thesaurus

[Campbell]

Hi all,

I'm looking to set up a custom thesaurus that would be hosted online so anyone can access it. The thesaurus would be very specific to a particular research area, in this case contemporary art. As an individual is writing a paper, the thesaurus would be able to suggest similar ideas, people, places, exhibitions, works, concepts that are related. The content itself isn't what I'm confused about though, it's the mechanics.

Ideally the thesaurus would also be editable by anyone as well.

I know that you can setup Word to access online thesauruses, but can't actually see any guide to how you can set one up.

If anyone can advice on a suggestion for this it would be greatly appreciated.

Thanks.
