摘要：In this paper, a formal description of knowledge element is given. On the basis of the formal description, a preliminary research about knowledge element acquisition method of emergency management system is proposed. For the characteristics of emergency management knowledge which is multi-field, multidisciplinary, multi-granularity and multi-dimensional, the knowledge element acquisition method is combined with web2.0 ideas that pay more attention to the interaction of the users. The knowledge element acquisition method provides unstructured and structured knowledge building interfaces and uses a Semi-Automatic Model of knowledge acquisition which is combined with a variety of key technologies. Because of this, knowledge element of the final acquisition is more comprehensive and scientific. ? 2011 IEEE.
