Enhancing Lexical Resources: Synset Expansion and Cross-Linking Between ItalWordNet and MariTerm

This paper outlines the first operation towards a full update of MariTerm, a WordNet-like resource on maritime terminology developed and maintained by CNR-ILC, in preparation for future compliance with FAIR principles (Wilkinson et al., 2016). The project focused on expanding and linking synsets between ItalWordNet (IWN), a general lexical database for Italian, and MariTerm to enrich IWN with maritime concepts. A semi-automatic pipeline was developed to facilitate this process, prioritizing critical semantic relations and automatic evaluation. Key outcomes include an enriched ItalWordNet with links to MariTerm concepts and a revised MariTerm with connections to IWN synsets. While further refinement is needed, this work marks a significant step toward integrating maritime terminology into ItalWordNet
