The ConanDoyle-neg (Morante and Daelemans 2012) is a corpus of Conan Doyle stories annotated with negation cues and their scopes, as well as the event or property that is negated.
it is noteworthy that in some of the corpora (BioInfer, Genia Event, Product Review, EMC Dutch, IxaMed-GS, and German negation and speculation corpus) negation cues have not been annotated, despite the fact that the cue is the element that denotes the presence of negation in a sentence and the one to which the rest of the elements (scope, event, and focus) are connected.
