植基於知識本體之多維軍事新聞檢索系統之設計

本研究提出多維度軍事新聞檢索架構，在知識表達方面，將軍事新聞以檢索者意圖、時間及地理空間三個維度進行新聞檢索，除了使檢索能更貼近新聞本質外，也因加入時間與地理空間的維度，加速收斂檢索者的查詢需求。本研究以國防部、軍聞社及青年日報之軍事新聞為資料來源，經由時間及地理空間資料的實體識別，與查詢關鍵字詞整合，透過時間軸、Google地圖等應用程式介面，以視覺化方式呈現軍事相關新聞標題、時間序列與地理空間分佈等整合資訊及相關統計資料，不僅降低使用者衍生的資訊過濾負擔，也減少因新聞分類不符期望而降低對新聞檢索介面的滿意程度或再檢索的新聞搜尋時間。

This study proposed a framework of multi-dimensional information retrieval for military news. In knowledge representation, this work not only introduced a framework of three dimensions information retrieval associated with user intent, temporal, and geographic location to closely meet the essence of news but increased temporal and geographical dimensions to speed up the convergence of user's requirement. In problem solving, the sources of military news are the Ministry of National Defense, Military News Agency and Youth Daily. After the entity recognition of temporal and geographic data from the source of military news, the search keywords are used to retrieve the related news. The search outcome is represented by the APIs of visualization, timeline and Google Maps, associated with the related news title and the statistical graphs about the occurrence time and places of news events to reduce the potential workload of information filtering for user and to lower the dissatisfaction of search result derived from misclassification of military news or the time of retrieval again.
