Cross-language projection of multilayer semantic annotation in the NewsReader Wikinews Italian Corpus (WItaC)

English. In this paper we present the annotation of events, entities, relations and coreference chains performed on Italian translations of English annotated texts. As manual annotation is a very expensive and time-consuming task, we devised a crosslingual projection procedure based on the manual alignment of annotated elements. Italiano. In questo articolo descriviamo l’annotazione degli eventi, delle entità, delle relazioni e delle catene di coreferenza realizzata su traduzioni in italiano di testi inglesi già annotati. Essendo l’annotazione manuale un compito molto dispendioso, abbiamo ideato una procedura di proiezione interlinguale basata sull’allineamento degli elementi annotati.
