+This corpus is an extension of the SFU Spanish Review Corpus (Brooke et al., 2009) with annotations about negation and its scope. It is a collection of 400 reviews of cars, hotels, washing machines, books, cell phones, music, computers and movies from the Ciao.es website. Each domain contains 25 positive and 25 negative reviews. Each review has been annotated at the token level with the lemma and the PoS and at the sentence level with negative keywords, their linguistic scope, the event and how the polarity of the sentence is affected by negation (if there is a change in the polarity or an increment or reduction of its value), also taking into account intensifiers and diminishers.

Negation detection is a challenge in most of the task related to NLP, so the availability of corpora annotated with this phenomenon is essential in order to advance in tasks related to this area. A thorough analysis of the problems found during the annotation could help in the study of this phenomenon.",
