| Abstract | In this paper we present a description of negation cues and their scope inbiomedical texts, based on the cues that occur in the BioScope corpus. Weprovide information about the morphological type of the cue, thecharacteristics of the scope in relation to the morpho-syntactic features ofthe cue and of the clause, and the ambiguity level of the cue by describing inwhich cases certain negation cues do not express negation. Additionally, weprovide positive and negative examples per cue from the BioScope corpus. Weshow that the scope depends mostly on the part-of-speech of the cue and on thesyntactic features of the clause. Although several studies have focused onprocessing negation in biomedical texts, we are not aware of publicly availableresources that describe the scope of negation cues in detail. This paper aimsat providing information for producing guidelines to annotate corpora with anegation layer, and for building resources that find the scope of negation cuesautomatically. |
