A semantic approach for the analysis of verbs in life sciences texts

This paper presents a corpusbased study of a group of lexical verbs in eighteenth and nineteenth century scientific texts. The study has a twofold aim. Firstly, it aims to select four types of verb classes (verbs of communication, desire, aspectuals and perception) identified by Levin and Noonan and explore their use in the Corpus of English Life Sciences Texts, a subcorpus of the Coru & ntilde;a Corpus of English Scientific Writing. Secondly, it aims to determine if the frequency of these verbs varies based on the gender of the authors. Further, the study seeks to ascertain if a shifting pattern could be attested in the use of these verbs throughout the two centuries examined in the corpus, at a time when the scientific register was already becoming established. The findings of the study obtained from the greater or lesser occurrence of the verbs in question over the two centuries indicate which ones were more frequent in Life Sciences texts, whether they were more commonly used either by men or women and whether there was a pattern of continued usage of these verbs in Late Modern English scientific language rather than a shift towards nominalisation in this type of discourse.
