Abstract
Based on the analysis of the characterizing of the emergency knowledge, an automatic constructing of semantic lexicon in emergency domain is proposed. In this paper, five dimensions are designed to represent the words of the emergency domain and an automatic construction system of semantic lexicon is provided. Based on the semantic dimension designed above, Self Organizing Map is applied to unsupervised clustering of Chinese words in emergency domain. The preliminarily experiment shows that our scheme is effective.
