This paper provided a method of the automatic discovery of the conjunctions' collocation pattern. Built a large corpus, and it was tagged by a Chinese automatic segmenting system, and tagged and proofed the connects words artificially. Set a threshold, and regard the collocation whose parameters were above of the value as candidates for the collocation pattern. The accuracy of tagging was 88.75% ,which indicated that this method was feasible. Many syntactic patterns are discoved in the research which will promot buliding a top-quality knowledg...
