Abstract  Based on PAT array,introducing LCP array to count the length of the common prefixes of text suffixes, a new algorithm without thesaurus is presented for extracting high-frequency words of Chinese text by scanning LCP arrary.The algorithm does not depend on segmentation dictionary and can extract any repeated string,especially the new words and combined words.Experimental results show that high-frequency words extracted by the algorithm achieve a high acceptance rate and this algorithm is more effective in extracting combined words than ICTCLAS.
