Abstract: Aiming at the problem that short text contained small words and various expressions, which led to ineffective clustering of the same category of text, we proposed a method to extend metaphorical words in short texts by using the rich lexical relationships in Chinese Wikipedia, which solved the shortages of the short text with less information and various lexical expressions. Experimental results show that the algorithm can effectively enhance the clustering effect of short text.
