AnCora-Verb-Ca is a verbal lexicon containing 2,141diferent verbs. In AnCora-Verb-Ca lexicon, the mapping between syntactic functions, arguments and thematic roles of each verbal predicate it is established taking into account the verbal semantic class and the diatheses alternations in which the predicate can participate. Each verbal predicate may be divided in different senses where each sense is related to one or more semantic classes (Lexical Semantic Structures), basically differentiated according to the four event classes -accomplishments, achievements, states and activities-, and on the diatheses alternations in which a sense can occur.

This lexical resource can be used for syntactic and semantic parsing, lexical representation, etc. This lexicon was used in the SemEval 2007 task: Multilevel Semantic Annotation of Catalan and Spanish

At present AnCora-Verb-Ca is the largest verbal lexicon containing information about verbal semantic classes, syntactic subcategorization, argument structure and the corresponding thematic roles, as well as diatheses alternations, freely available.
