【目的/意義】案例庫是以規范化方式存儲記錄網絡輿情應對的知識及經驗。作為整個案例推理的前提,案例庫構建關系到推理過程整體運行效率以及決策支持的正確性。【方法/過程】通過集合突發事件網絡輿情案例信息,提取案例公共屬性特征,以自然語言描述案例屬性,運用本體技術構建出突發事件網絡輿情案例庫表示模型。【結果/結論】案例庫本體模型的構建不僅為案例表達提供語義表示的正式方法,而且闡明了本體內部組織建構模式,在案例結構規范化的基礎上,增加了案例知識的重用頻率,促進了其共享。

【Purpose/significance】The case base is a standardized way to store and record the knowledge and experience of network public opinions. As the premise of the whole case inference, the building of the case base is related to the correct operation of the inference process and the decision support.【[Method/process】By collecting the public opinion case information of emergencies and extracting the characteristics of public attributes of cases, the case attributes are described innatural language, and the ontology technology is used to build a case representation model of network public opinion casesof emergencies.【Result/conclusion】The construction of case base ontology model not only formally provides semantic rep-resentation for case expression, but also clarifies the model of hierarchical organization construction, standardizes the casestructure, improves the reusability of case knowledge, and facilitates sharing.
