The present invention relates to an address structuring method and device. The address structuring method comprises: step 10, segmenting an address text into address word sequences; step 20, marking the part-of-speech of each address word in the address word sequences according to a predefined part-of-speech marking set reflecting address word features; and step 30, performing dependency syntax analysis on the marked address word sequences according to a predefined address word dependency relationship rule, and generating a dependency syntax diagram structure reflecting the address structure by using entity address words as nodes and using a dependency relationship between the entity address words as edges. The present invention also provides an address structuring device. According to the address structuring method and device in the present invention, a dependency syntax diagram structure can be efficiently and automatically generated to represent a dependency relationship between words in an address text; a manual intervention policy is simple, and a great amount of background knowledge is not required; the present invention expands a dependency tree structure, so that the relationship between address words can be expressed in a diagram manner.
