SynSemClass 4.0

The SynSemClass synonym verb lexicon version 3.5 investigates, with respect to contextually-based verb synonymy, semantic ‘equivalence’ of Czech, English, and German verb senses and their valency behavior in parallel Czech-English and German-English language resources. SynSemClass4.0 is a multilingual event-type ontology based on classes of synonymous verb senses, complemented with semantic roles and links to existing semantic lexicons. The SynSemClass is not only enriched by an additional number of classes but in the context of content hierarchy, some classes have been merged. Compared to the older version of the lexicon, the novelty is the definitions of classes and the definitions of roles. Apart from the already used links to PDT-Vallex, EngVallex, CzEngVallex, FrameNet, VerbNet, PropBank, Ontonotes, and English WordNet for Czech and English entries the new links to German language lexical resources are exploited for German verb entries, such as Woxikon, E-VALBU, and GUP. The German part of the lexicon has been created within the project Multilingual Event-Type-Anchored Ontology for Natural Language Understanding (META-O-NLU) by two cooperating teams - the team of the Charles University, Faculty of Mathematics and Physics, Institute of Formal and Applied Linguistics, Prague (ÚFAL), Czech Republic and the team of the German Research Center for Artificial Intelligence (DFKI) Speech and Language Technology, Berlin, Germany
