This paper presents a three-step approach for interoperabilising heterogeneous semantic resources. Firstly, we construct homogeneous representations of these resources in a pivot format, namely OWL DL, with respect to the semantics expressed by the original representation languages. Secondly, mappings are established between concepts of these homogenised resources and stored in a so-called articulation ontology. Thirdly, an approach for ranking those mappings is suggested in order to best fit users' needs. This approach is currently being implemented in the Semantic Resources Interoperabilisation and Linking System (SRILS). The mapping results as well as the work to be done are discussed.
