dc.description.abstract" 過去餐飲業評估顧客服務體驗與評價時,最常被使用的方法即為設計內部「用餐滿意度問卷」,以顧客被動填寫滿意度方式進行服務品質的衡量。然而,此種方式僅能提供靜態的資訊蒐集,難以瞭解顧客在服務過程中的動態體驗與回饋。近年顧客體驗當道,企業經營從產品主導的邏輯,轉向服務和顧客主導的邏輯(Service-Dominant Logic, S-D Logic)演進的現象,其主張以顧客為中心,強調企業可以與顧客價值共創(Lusch Vargo, 2006; Lusch, Vargo, Tanniru, 2010; Vargo Lusch, 2016; Vargo, Maglio, Akaka, 2008),在顧客服務網路中,藉由彼此間的互動及資源整合的活動中所實現。 本研究透過此觀點,我們以數據挖掘(Data mining)方法,了解線上評論消費者真實的聲音 (Voice of the Customer, VOC),並使用隱含狄利克雷分布(Latent Dirichlet allocation, LDA)分析消費者評論資料,來更深入地瞭解消費者的體驗,與識別評論背後的消息意圖,並結合服務藍圖(Service Blueprint)服務流程的設計工具,達到企業、消費者價值共創互動的機制。 本文研究的數據集來自中國知名的飲食評論平台:25,670個店家共266,544條線上評論,以及中國外送平台的消費者評論,並將這些評論資料依餐飲服務接觸型態區分成三類,包括:餐桌服務、櫃檯式服務、外送服務,使用隱含狄利克雷分布演算法(Latent Dirichlet allocation, LDA),其為非監督式的機器學習技術,來自動提取顧客在不同餐飲型態下的意見回饋,進行研究與滿意度因子分析。 最終LDA主題演算法萃取出餐飲三種不同型態下,各12項顧客評論中所關心的關鍵主題構面,接著與過去研究比較,發現本研究之方法所歸納出的主題,是可以涵蓋與解釋過去研究的結果,並有其可信度;更重要的是,還找到了原研究中幾乎沒有出現過的新的滿意度因子,包括事前準備資訊、優惠活動、新品、外送天氣、下單操作,這些都豐富了企業決策的數據庫。 將主題分析構面應用服務藍圖(Service Blueprint)與滿意度評分做進一步分析,洞察出商業意涵。在分析中發現不論哪種型態的服務,在負面評論中都是與顧客服務的相關主題(桌邊服務、店員服務、客服)占比最大,由此可以推論,不論與顧客接觸時間長短,人與人間的服務品質是影響顧客情緒產生的重要因素。而在餐桌服務的正面評論中「餐廳內裝」是最高比例會被提及;櫃臺式服務則是「優惠活動」;「外送天氣」最常在外送服務中提到,這幾項主題都會使消費者很有感的產生正面感受,因此企業可以掌握這些資訊做內部管理與外部行銷。 透過分析大量的用戶生成內容來了解消費者的真實聲音,對於競爭激烈的餐飲行業具有重要意義。此次結果資料也可以提供給未來AI客服系統前置訓練的資料建置,來準確歸納消費者的疑問,創造消費者與餐廳價值共創的新服務架構。 "zh_TW
