P. 711-722Thesauri are valuable knowledge organization systems (KOSs) that support advanced information retrieval. The Semantic Web has
brought a renewed interest in thesauri as a support for semantic searches and other added-value services. Tools that manage thesauri
permit them to be created, edited and queried. The integrity restrictions on thesauri should also be controlled by these tools.
However, there is also the possibility of thesaurus exchange, which becomes relevant in the Semantic Web context, where information
exchange is a crucial facility. In fact, interoperability at the information level has received an important boost with the stabilization
of the SKOS standard as a World Wide Web Consortium (W3C) Recommendation. Furthermore, the feasibility of integrating software
is a valuable feature for software developers. An evaluation framework for thesaurus tools is proposed, which includes the issues
of functionalities, construct support, integrity, information interoperability and feasibility of integrating software. It is original in focusing
on SemanticWeb conformity and interoperabilityS
