突发事件案例是各种非常规突发事件发生后事件演变过程、应急处置和事后恢复与总结的真实记述。基于突发事件案例的特征和应急平台人工智能技术对案例的复用要求,根据系统工程的思想,设计了突发事件案例元模型、案例库组织模型、案例库主题词表、数据库系统及其高级应用方案。

Keywords
list and that of advanced application
the system engineering principles
the resolutions of the unit model
as well as the organization model.And
then
we have made a detailed discussion of the database system function and its due targets.The working principle of the database mainly includes three parts
that is
the selection principle of the original emergency cases
the case construction principle and the whole design principle.The case unit model includes seven first-level fields
such as the indexing field
case summary
response process
cause analysis
case property
lessons and case origin.The indexing field contains thirteen sub-fields
that is
the case caption
the case abstract
key words
category
nation
province
district
location
date
casualty
emergency scale
emergency property and the property damage.As to the organization model
it can be made up of four first-level fields
that is
the natural disasters
accidents
public sanitation emergency and society security
and fifty-six second level fields.Next
we have made a detailed presentation of the structure and construction principle of the key word list.And
finally
we have brought forward a three-level construction method
i.e.the model-View-Controller construction.In the aspect of advanced application of the database system
we would like to recommend the following analysis systems
that is
the case based reasoning
the grey relational analysis and the single factor analysis.Therefore
it can be seen that the database system design for the provincial-level oriented emergency platform we propose here can be expected to provide a new method for the storage
management and application of emergency platform oriented emergency events.Key words： safety control
case database
emergency platform
emergency
design

文摘
传统的农业知识服务是基于关键字而不是基于内容的,查全率和查准率都有待提高,运用基于语义网的知识表达,可以真正实现语义级的知识服务。分析了农业知识服务系统的现状并指出其不足,阐述了语义网技术和本体构建方法;构建基于语义网的农业知识服务系统模型并给出了它的框架结构和功能设计;并设计了适合种植、生产与销售实际的茶叶本体,部分实现了茶叶领域的农业知识服务系统。

the recall rate and precision rates are to be improved. The knowledge representation based on semantic Web can truly achieve the semantic-level knowledge services. The status of agricultural knowledge services system was analyzed and its shortcomings were pointed out
semantic web technologies and building methods of ontology were elaborated
the model of agricultural knowledge services system based on the semantic Web was built
the framework and function design were given. An ontology adapting to the plantation
production and market in tea field was constructed
tea knowledge services system was partly achieved.Key words Knowledge services
