Emergency document structure modeling based on knowledge element
摘要
Abstract
Low utilization and search of emergency document knowledge result in making emergency decision inefficiently and slowly for the deciders.From the perspective of knowledge system engineering, this paper conducted in-depth study on the fine-grained knowledge discovery mode of emergency documents and provided a new way for decision-makers to quickly and effectively use emergency document knowledge by emergency document knowledge modeling based on knowledge element.The modeling process included the analysis of physical and logical structure, the navigation link based on knowledge element and the knowledge reasoning and retrieval.In the process of physical analysis, extracted the metadata and processed the document structured.In the logical analysis proposed an approach to extract the knowledge element.Established the link between the knowledge and the structured document, also developed a prototype of emergency knowledge decision support system and made an examination.The results indicated that the modeling approach is practical and effective.关键词
