Abstract: Since the unknown word in military texts is excessive, and the feature of some words is incomplete, the word segmentation method which is based on lexical chunk as the unit was provided. word segmentation was divided into some sections:bidirectional scanning in the text in the base of dictionary,marking the various and segment the words;deleting the stop-words which share the same segmentation results, then count words mutual information and adjacency frequency by the first times word segmentation, according to this counting result, the lexical chunk with relevant words can be judged and signed. At last,picked up the signed various segment and lexical chunks to audit and deal with them artificially. The experimentation shows that after the word combination, the lexical chunk bears much more feature information which shares a better effect of the process.
