Thesaurus Management - Semantic Web

This looks interesting - PoolParty, a company in Austria, has developed software for creating and managing a thesaurus. It supports SKOS and can be used to analyze text and do "semantic indexing".

PoolParty is a thesaurus management system and a SKOS editor for the Semantic Web including text analysis functionalities and linked data capabilities. The system helps to build and maintain multilingual thesauri providing a simple user interface and a couple of semantic services. PoolParty can be used to implement semantic search or can be integrated into existing systems like CMS, DMS or Wikis.

There are several screencasts and screenshots to demo the product. Registered users have access to a full demo. As well there is this very useful page on Application Scenarios and Use Cases.
