It is indispensable to index stop-word before word segmentation in knowledge extraction.The key technique of processing stop-word is how to select stop-word,acquire and organize stop-word lists,and match stop-word.To recognize stop-word,constructing stop-word list is necessary.In processing stop-word,recognizing false stop-word can decrease noise.According to experiment,processing stop-word can not only save segment time,but also improve following syntactic analysis efficiency.
