This paper describes the process of building SardaNet, a linguistic resource for Sardinian language including the different linguistic varieties in Sardinia. SardaNet aims at identifying the semantic relations between Sardinian terms, by manually mapping existing WordNet entries to Sardinian word senses. The work, still in progress, has been developed in collaboration with the University of Cagliari. After discussing some linguistic peculiarities, the paper presents the basic steps of the construction process, the method and the tools involved, the issues encountered during the development and the current version of SardaNet.
