Semantic interoperability of multilingual language resources by automatic mapping

The PMKI project is an European Commission action aiming to create a public multilingual knowledge management infrastructure to support e-commerce solutions in a multilingual environment. Such infrastructure will consist in a set of tools able to create interoperability between multilingual classification systems (like thesauri) and other language resources, so that they can be easily accessible through a Web dissemination platform and reusable by small and medium-sized enterprises (SMEs), as well as by public administrations. In this paper the standards used to represent language resources and a methodology for automatic mapping between thesauri, based on an information retrieval framework, are presented.
