SynSemClass lexikon version 5.0 explores the contextual semantic "equivalence" of Czech, English, German, and Spanish verbs, together with their valence behaviour in parallel Czech-English, German-English, and Spanish-English texts. SynSemClass5.0 is an ontology based on classes of multilingual verb synonyms, supplemented by semantic roles. The SynSemClass event-type ontology is enriched by a considerable number of new classes and the inclusion of Spanish synonyms is a novelty compared to older versions. Again, it contains references to other semantic lexical sources. In addition to the references already used (to PDT-Vallex, EngVallex, CzEngVallex, FrameNet, VerbNet, PropBank, Ontonotes Woxikon, E-VALBU, GUP, and German FrameNet), SynSemClass also includes references to Spanish linguistic lexical resources: to ADESSE, SenSem, AnCora, and Spanish WordNet and FrameNet. Examples of sentences in which multilingual synonyms have been used are also included.
