Linking CompL-it to the LiITA Knowledge Base

This paper presents the integration of CompL-it, a Linked Open Data (LOD) computational lexicon for contemporary Italian, into LiITA (Linking Italian), a Knowledge Base (KB) designed for linguistic interoperability. CompL-it contains over 101k lexical entries enriched with detailed morphological and semantic information, derived from multiple authoritative sources and modelled using the OntoLex-Lemon vocabulary. The linking process involved aligning lexical entries with lemmas in the LiITA’s Lemma Bank (LB), addressing both exact and ambiguous matches through systematic and semantically informed strategies. Moreover, 12,739 new lemmas were added to the LiITA LB. This integration enhances the expressiveness and interoperability of LiITA, enabling complex SPARQL queries that exploit the semantic network encoded in CompL-it. Examples are provided to demonstrate the advantages of querying interlinked resources.
