7 WHAT

8 K Dictionaries multi-language Global Series Spanish set of the K Dictionaries (KD) multi-language Global Series (24 languages) The approach followed in this series is to compile for each language a core vocabulary as a standalone project and have it translated to other languages in more projects. Not biased towards any language, and each is represented on its own terms. Translated to another language at a later phase, creating a pair-specific, and thus pairsensitive, interlingual representation 4

12 5 tasks to migrate resources into linked data (Vila Suero et al., 2014): 1. Data exploration 2. URI naming strategy definition 3. Modeling 4. RDF generation 5. Linking

14 Modeling lemon-ontolex Model for representing linguistic information in RDF(s) (semantics by reference) An ontology-based semantic lexicon would leave the semantics to the ontology, focusing instead on providing domain-specific terms and object descriptions in the ontology. (Buitelaar, 2010) Concise and descriptive (external repositories of linguistic categories) Modular and extensible (5 modules)

15 The origins LMF -Lexical Markup Framework (ISO 24613) XML LexInfo, LIR Represent lexical information relative to an ontology OWL SKOS (W3C Standard) Designed for Taxonomy/Vocabulary representation in RDF Nowadays de facto standard for transforming linguistic resources into the linked data format From McCrae, J., lemon: The Lexicon Model for Ontologies SD-LLOD-15

19 CONCLUSIONS

20 LD paradigm EN DE Innovative way of representing and linking data Keeping language specificities as much as possible, in a crosslingual graph, bottom-up fashion ES FR IT Retrieving language information by linking translations In the KD case, RDF links contribute to automatic growth of lexical resources, at a different pace One-stop shop, rather than many shops 4
