Abstract Based on Conditional Random Fields(CRF), the article identifies the Chinese prepositional phrase. In order to identify the prepositional phrase effectively, the article counts and analyzes the external and internal linguistic features of the prepositional phrase. The prepositional phrases without nesting and nested prepositional phrases are identified with the complex feature model,and in open tests,the best F value can reach 90.29% and 89.99% respectively.
