摘要
[目的/意义]利用本体对重大突发事件下网络舆情信息源及要素等进行分析,更好地管理与组织相关数据,为设计重大突发事件网络舆情案例数据库奠定基础,进而辅助政府进行精准决策。[方法/过程]分析并提取异源平台网络舆情数据属性与属性值,依据舆情传播过程及要素分析本体核心概念、数据属性及关系,利用UML完成本体数据模型的构建。[结果/结论]为各类突发事件网络舆情异构信息源统一描述、组织、存储与管理建立了数据模型,为各类突发事件进一步应急决策与防范提供了有力支持。[局限]文章对数据模型的研究未进一步细化和解释相关概念、关系和数据属性,也未完成数据库存储平台的实际搭建并对数据的属性、属性值及数据类型进行深入分析。
[Purpose/significance]By using the ontology to analyze information sources and elements of online public opinion under major emergencies,this article can better manage and organize relevant data,laying the foundation for designing a database of online public opinion cases of major emergencies,and thereby assisting the government in accurate decision-making.[Method/process]By analyzing and extracting the attributes and attribute values of web opinion data from heterogenous platforms,the ontology core concepts,data attributes and relationships are analyzed based on the process and elements of public opinion dissemination,and the ontology data model is constructed using UML.[Result/conclusion]It establishes a data model for unified description,organization,storage and management of heterogeneous information sources for various types of emergencies,and provides powerful support for further emergency decision-making and prevention of various emergencies.[Limitations]The study of the data model in this paper does not further refine and explain the relevant concepts,relationships and data attributes,nor does it complete the actual construction of the database storage platform and conduct an in-depth analysis of the data attributes,attribute values and data types.
