Contrast-Ita Bank consists of 169 news stories (for a total of 65,455 tokens). The documents correspond to the documents of the Fact-Ita Bank corpus, annotated with factuality information and, partially, with negation (Fact-Ita Bank-Negation). Originally, the documents were selected from the larger corpus Ita-TimeBank: a language resource manually annotated with temporal and event information. The same documents are also part of the I-CAB corpus: a corpus of Italian news annotated with temporal expressions and different types of entities (i.e. persons, organizations, locations, and geo-political entities). Despite the existing information that had already been annotated in these documents, the annotation of contrast was carried out on raw text.
In Contrast-Ita Bank we annotated explicit and implicit relations of contrast (CONTRAST and CONCESSION) for a total of 372 relations.
