    Abstract: 意見調查指透過詢問的回答方式,蒐集回答者感覺或意見的資料蒐集方法,具有花費時間與成本高等缺點;網路意見分析指從網路資訊中進行意見分析能夠自動分析大量的資料,比起意見調查具有效率較高等優勢。因此本研究主旨於利用部落格與微網誌進行網路意見分析,並與意見調查比較以公共議題為例,除了比較傳統民調並將網路意見製成意見摘要,期望本研究能提供未來社會公共議題研究者之參考。研究方法為系統發展研究法,建置網路意見分析的雛型系統,發展各系統功能包含網頁擷取技術、資料前處理、CopeOpi網路意見分析工具進行意見分析與意見摘要步驟。研究結果顯示「廢除死刑」議題的結果與民調結果的意見傾向趨勢相同,且系統評估的結果為負面意見效能最好,可推知網友有負面情緒時較易於發表在網路平台上。總結而言,此研究希望能透過將網路意見分析技術運用於公共議題上期望能達到輔助民調的效果,聆聽網路上之意見聲音。

Apart from comparing to the opinion poll of telecommunications, we look forward to offering the public issue researchers a reference in the future. This study adopts Systems Development Methodology, and it uses a web crawler, data preprocessor, CopeOpi online textual opinion analysis and opinion summarization to build an online textual opinion analysis system.
