Proceedings of the conference Terminology and Artificial Intelligence 2015 (Granada, Spain) 5 Multilingualism and Conceptual Modelling Ricardo Mairal Facultad de Filologa Dpto. de Filologas Modernas y sus Lingüı́sticas Paseo de la Senda del Rey, 7 UNED Madrid 28040 rmairal@flog.uned.es One of the leading motivations behind the multilingual semantic web is to make resources accessible digitally in an online global multilingual context. Con- sequently, it is fundamental for knowledge bases to find a way to manage multilin- gualism and thus be equipped with those procedures for its conceptual modelling. In this context, the goal of this paper is to discuss how common-sense knowledge and cultural knowledge are modelled in a multilingual framework. More particu- larly, multilingualism and conceptual modelling are dealt with from the perspective of FunGramKB, a lexico-conceptual knowledge base for natural language under- standing. This project argues for a clear division between the linguistic and the conceptual dimensions of knowledge. While the conceptual layer is organized into three modules, which result from a strong commitment towards capturing semantic knowledge (Ontology), procedural knowledge (Cognicon) and episodic knowledge (Onomasticon), the linguistic level includes a lexicon and a grammaticon (a syn- tactic repository of constructional schemata). Cultural mismatches are discussed and formally represented at both the conceptual and the linguistic levels of Fun- GramKB.
