This chapter is concerned with verb collocations in the specialized language of science. I pay attention to their semanticity, since my main objective is to discover the topics evoked in terms of their integrating elements. The methodology applied is as follows: first, I compile a specialized corpus of research articles; second, I automatically extract a list of collocation candidates, which is manually revised; third, the selected collocations are semantically classified. As this work is motivated by a previous study on noun collocations, I perform a comparative analysis. The findings are that noun and verb collocations share similar semantic frames, although the method employed in each study yields different, but complementary, results.
