The paper presents a review of principles and applicability of collostructional analysis — a cluster of corpus methods developed by Anatol Stefanowitsch and Stefan Th. Gries since 2003. Collostructional analysis measures the strength of association by which lexemes are attracted to a particular position in a construction. It derives from the Construction Grammar concept of construction as conventionalized pairing of form and meaning. Collostructional analysis allows for systematic measurements of the degree of conventionalization of constructions. The paper introduces various types of collostructional analysis and provides an overview of research areas where collostructional analysis has been employed. It concludes with a case showing how collostructional analysis can be applied to the description of Czech.
