Multilingual translations of the MIC21 ontology classes

The classes of the MIC21 ontology of visual objects are translated into 25 languages (English, Albanian, Bulgarian, Basque, Catalan, Croatian, Danish, Dutch, Galician, German, Greek, Finnish, French, Icelandic, Italian, Lithuanian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovene, Spanish, and Swedish). Openly available wordnets have been used from the Extended Open Multilingual WordNet. For the Ontology classes which are not inherited from WordNet the appropriate WordNet hypernyms are taken. Where WordNet translations are not available, some additional sources of translations as BabelNet are employed. The Multilingual translations of classes are presented in a separate JSON file which contains information about the language and the translation source (sample). The translations of the Ontology classes are accompanied by their synonyms, the concept definition and usage examples (if available in the sources). The explicit association of objects and images with appropriate text fragments is relevant for multilingual image caption generation, image-to-text alignment and automatic question answering for images and video.
