【Abstract】 Chunk parsing is an effective method to decrease the difficulty of language parsing.This paper proposes a formal description representing the characteristics of Chinese chunks.Based on the description,a statistical algorithm is accomplished to recognize definite levels of Chinese chunks.The experiments have proved that the algorithm gives a high accuracy for shallow parsing of real Chinese texts with robustness.更多还原
