國立臺灣師範大學 大眾傳播研究所 蔣旭政所指導 林晏竹的 AI客服聊天機器人與媒介豐富度對消費者態度與行為意圖之影響—以電商平台為例 (2021),提出Django model manager關鍵因素是什麼,來自於聊天機器人、人工智慧、客戶服務、媒介豐富度、社會資訊處理模式、消費者行為、電商平台。

AI客服聊天機器人與媒介豐富度對消費者態度與行為意圖之影響—以電商平台為例
為了解決Django model manager 的問題,作者林晏竹 這樣論述:
行動商務與即時通訊軟體的蓬勃成長使聊天機器人受到高度的發展與運用。為了提供良好的客戶服務,電商平台利用聊天機器人作為即時服務媒介創造更優質的服務體驗。然而,任務導向聊天機器人卻無法解決在既定腳本外更深入、細微的消費問題,進而影響消費者行為。由此,本研究透過將人工智慧應用於客服聊天機器人,期望藉此提升消費者行為。本研究以電商平台為研究背景,採2(對話導向AI聊天機器人 vs. 任務導向聊天機器人)x2(高媒介豐富度 vs. 低媒介豐富度)二因子組間實驗設計,且就個人相關使用經驗(網路購物售後服務經驗)做進一步研究分析,並以聊天機器人態度、持續使用意圖與口碑推薦意願等三元素為消費者行為組合作為依
變項,探討自變項與依變項兩者之間的交互作用與影響。 本研究結果證實:(1)對話導向AI聊天機器人相較於任務導向聊天機器人,對於消費者行為有較佳的影響;(2)高媒介豐富度相較於低媒介豐富度,對於消費者行為有較正面的影響;(3)無論是何種媒介豐富度,在對話導向AI聊天機器人中,對於聊天機器人態度、持續使用意圖與口碑推薦意願皆不會有差異;(4)在任務導向聊天機器人中,高媒介豐富度相較於低媒介豐富度,會產生較佳的聊天機器人態度、持續使用意圖與口碑推薦意願;(5)使用客服聊天機器人後,相較於使用前會產生較正面的消費者行為;(6)具有網路購物售後服務經驗的消費者,相較於無網路購物售後服務經驗
的消費者,會產生較佳的持續使用意圖,但在聊天機器人態度與口碑推薦意願則無顯著差異。
設計與製作具高互動之網站伺服器平台
為了解決Django model manager 的問題,作者彭俊濠 這樣論述:
在現今的時代,資訊化已成為各行業的基礎,而網站的規劃與建置需求也愈來愈高,需要更加仔細的考慮,網站能為我們做些什麼?能提供什麼樣的功能?然而國內部分網站仍停留於單純的顯示資訊與新增、修改、刪除資料等方式,有些甚至是紙本人工作業,缺少了平台化、標準化與管理者和使用者之間的「互動性」。為了能更加明確與更有幫助的建置具有高「互動性」網站,本論文與精英國際教育集團及新北市公立托育中心合作,希望藉由專業的知識協助與理解目前業界工作流程,進而設計並實作出符合業界實際需求之具高互動性網頁管理平台。本論文提出了「親子照護平台」的設計與實作,將具高互動網站以服務平台的方式呈現,並在服務平台上設計出五大功能模組
分別為「前台服務模組」、「後台管理模組」、「訊息服務模組」、「操作紀錄模組」、「排程管理模組」。此服務平台支援手機、平板、筆記型電腦和桌上型電腦等各種設備上網使用,並提高使用者對親子機構的資訊獲取管道、管理者對使用者需求的掌握的和管理者與使用者之間的互動性,且保留網站的彈性令未來可以依照需求進行擴充。
