Semantic Interoperability among Thesauri: A Challenge in the Multicultural Legal Domain

In the last few years crucial issues like cross-language legal information retrieval, document classification, legal knowledge discovery and extraction have been considered in theory and in practice. The availability of services allowing cross-language and cross-collection retrieval is a growing necessity. This paper focuses on the need to develop solutions for automatic, language-independent procedures to provide interoperability between mono/poly-lingual thesauri at national and European levels. This will guarantee sustainable and scalable services enabling to manage the multilingual complexity of the European Union legal context to be used for cross-language and cross-collection legal information retrieval. Wider use of the service can also be envisaged as support to legal translation services, as well as in general to promote integration and sharing of widespread and heterogeneous legal resources, providing new market opportunities for stakeholders to exploit the economic potential of public sector information in a multilanguage environment.
