The construction of preposition knowledge base in the past had given more prominence to the study of semantics of prepositions as well as collocations of prepositions and their complements， while there had been few work on systematic research and knowledge extraction of preposition-verb collocations。 The characteristics of Chinese that prepositions are well-developed and that the heads of sentences being verbs determine that the study of preposition-verb collocations is crucial。 Being based on a technology of structures retrieving and fully utilizing phrasal structure attributes as well as information of structures， we have extracted 16033 pairs of preposition-verb collocations from a large-scale corpus， and came up with a method for measuring the closeness of a preposition-verb collocation， which was preliminarily proved to be superior to the method of absolute frequency。
