This paper is an exercise in corpus-driven metaphor research. In the main part, we demonstrate the use of collocation evidence for the construction of Fillmorian semantic frames for four expressions in the 'War' domain - FIGHT WAR, DECLARE WAR, BATTLEFIELD and BATTLEGROUND. We combine manual categorization of collocates identified in concordance lines extracted from the British National Corpus (BNC) with automatically derived collocation statistics (z-score). We then show how corpus citations demonstrate the scalar nature of metaphor. Finally, we use the L- Word Query function in the BNC Sara concordancer to identify and categorize metaphorical compounds containing the word war. General comments regarding the usefulness of corpus-based empirical methods for metaphor research are offered throughout the paper and in the conclusions.
