| dc.description.abstract | 近年來，人們大量在網路上發表自己的想法及言論，因考慮到這些大量網路言論的價值，部份學者開始對這些資料做情感分析，若是能將情感分析和政治領域做結合，就能在短時間內得到民眾對候選人的支持率或是施政的滿意度，節省傳統問卷的時間及人力。然而，因情感分析資料來源來自於網路，搜集到的詞語勢必充斥著大量的網路用語，這些網路用語也含有強弱不等的情感在內，若將這些非正規情感詞排除在研究範圍之外，將會損失大量有價值的資料，因此，建立一個網路用語情感辭典，對以網路言論做情感分析有重大的作用。本研究蒐集2016總統大選前一個月的Facebook文章，分析各候選人的支持率，結果顯示在Facebook上以情感分析挖掘網路社群媒體民眾意見較趨向特定族群，和實際支持率有落差，。網路用語情感辭典目前因網路文章不嚴謹、結構不完整問題受到了很大的限制，但在一些限制條件下，正確率有微幅提升。而辭典的建制雖然還不是很完整，但也為將來分析網路文章時所需的領域專用情感辭典，做為一個開端。 | zh_TW |
