In the last two decades, interest in the role played by phraseological units in the discourse of science has grown. Linguists have agreed that collocational frameworks help to structure the text and display a more restricted set of senses when used in this context. This paper aims at contributing to the study of collocations in the research article (RA). To this end, more than 400 collocations are analyzed in terms of Fillmore's Frame Semantics theory. Our methodology is corpus-based and explores adjective + noun open domain collocations extracted from the British National Corpus (BNC) in a specific corpus of more than three million words. The findings suggest that these collocations convey specific meanings when they are used in this genre, being the headword the element evoking the semantic frame of the combination and the collocate expressing a feature of the former. The frames evoked reflect the semantics of science and their combination shows the anatomy of the RA.
