摘要
【目的/意义】突发事件新闻具有连续性特征,现存的语义模型无法很好地表示这一特征,通过构建突发事件新闻语义模型可以实现对这些连续性信息的深层次语义描述和利用。【方法/过程】本文根据由表及里的建模思维,构建了一个突发事件新闻深层次语义描述本体模型。该模型分为元数据和内容语义两部分,内容语义部分以事件为起点、以连续性情景和动作为核心。在对突发事件新闻案例进行语义描述的基础上,实现了语义检索、语义推理、语义数据可视化分析等应用。【结果/结论】通过语义标注和应用实验,验证了该模型的可用性。【创新/局限】本文提出的突发事件新闻本体模型,较好地解决了突发事件新闻连续性信息的语义标注问题。
【Purpose/significance】The emergency news has continuity feature.However,the existing semantic model cannot express this feature well.By constructing semantic model for emergency news,deep semantic description and utilization of these continuous information can be realized.【Method/process】According to the thinking of modeling from the surface to the inside,the semantic model for emergency news was divided into two parts:metadata and contentsemantic.The latter part takes the event as the starting point and the continuous situation and action as the core.【Result/conclusion】Through the semantic annotation and application experiments,the availability of the model was verified,and the semantic annotation problem of continuity information of emergency news was solved.【Innovation/limitation】The emergency news ontology model proposed in this paper can better solve the problem of semantic annotation of continuity information of emergency news.
