基于知识图谱的结构化应急数据展现研究
|
摘要
当面对突发事件时,指挥员通常同时面临有效信息不足和垃圾信息过载困境,可用信息在短时间内难以有效发现和利用,信息与决策之间存在着巨大鸿沟,基于知识图谱对应急数据进行组织和展示提供一种可行的解决路径。简要分析基于知识图谱对应急数据进行组织的优势,构建应急知识图谱的信息搜索模型,提出应急知识图谱的构建步骤。
When emergencies happen,commanders often face with information overload dilemmas. The available information is difficult to use effectively in a short period of time. There is a huge gap between information superiority and decision-making advantage. The mapping knowledge domain is one of the available ways to solve this puzzle. Briefly analyzes the value of mapping knowledge domain for emergency data,studies the data composition model of emergency mapping knowledge domain,and proposes the steps of constructing emergency mapping knowledge domain.
