    Abstract: 近年來,受惠於網路的盛行及其帶來的便利性,許多網
    站得以收集到大量的使用者對於商品之評價以及評論,運用
    這些使用者的回饋資料進行分析,以更精準的進行商業行銷
    正是當今浪潮。
    而推薦系統廣泛應用於商業行銷,常用的推薦系統之計
    算理論,乃依據使用者對商品的評分進行協同式的過濾,以
    找出合適的產品給予推薦,其理論的基礎是品味相近的消費
    者應該會喜歡類似的商品,使用者對商品的評分即為此模式
    所採用的依據,例如:運用User-based Collaborative Filtering
    ,可以找出與被推薦者的特徵值類似的使用者,並以類似使
    用者中較高評分的項目作為推薦清單,這種方式能得到相當
    不錯的推薦結果,且計算的運算量亦不太大。
    相較之下,以使用者對商品的文字評論作為依據的推薦
    方法則較為少見,但我們認為文字訊息在推薦系統中亦佔有
    相當份量的重要性;直覺上,將使用者的評分與其文字評論
    作結合進行分析,應可更完整呈現該使用者的意向,並進而
    應能改進推薦系統之推薦效能。在這份論文研究中,我們嘗
    試結合使用者對商品的評分與文字評論於推薦系統中,並以
    一份取自TripAdvisor.com的使用者對於飯店評價之資料集進
    行實驗,透過libFM 建立推薦模型;從實驗結果探討中印證
    了我們的想法:使用者的文字評論訊息的確能夠用以改進推
    薦系統之效能。
