摘要 於2013年正式公開的GDELT專案號稱能監控全球65種發行語言的數位新聞媒體，利用現今完善的機器學習演算法、自然語言處理及深度學習等先進人工智慧技術，將寶貴的新聞資料，萃取與轉換成具有58組欄位資訊的結構化資料，提供各領域進一步研究與應用。本研究以GDELT新聞事件資料集來開發大數據資料分析流程，並且利用Spark ML Pipeline的技術，在亞馬遜網路服務（AWS）的雲端平台上，完成以滾動式機器學習演算法，來進行以GDELT資料為主的美國標普500（S&P 500）股市指數追蹤，與特定「佔領華爾街」事件影響力的因果分析。本研究所採用的45天滾動式隨機森林模型，在歷史指數的追蹤與預測表現上，獲得了方均根差僅43.35（誤差2.12%）的優異成果；於雲端系統上的15分鐘近即時滾動式預測誤差，更是低於1.5%。在因果分析方面，本研究採用貝氏時間序列模型分析「佔領華爾街」事件影響股市的反事實指數，闡釋該事件的發生與後續效應，促使S&P 500股市指數在觀察區間中上漲116.76點。
