口碑是資訊傳遞者與接收者面對面所產生的資訊溝通行為,這種商業溝通行為是非商業意圖的,為談論有關某一品牌、產品或服務的訊息傳播過程,是影響顧客消費決策的重要因素。隨著網路的發展,口碑不只限於以傳統口耳相傳的方式傳播,而漸漸將顧客的意見、經驗與評論等藉由消費者自主媒體(CGM),如討論區、留言板、部落格等空間傳播,形成新型態的網路口碑。過多的網路口碑資訊,對人類來說不易閱讀,更別說透過網路口碑制定消費決策。因此本研究嘗試整合網路口碑資訊,解析商家評價,透過各項指標針對商家產品、服務做評論,透過各項指標比較商家之間的差異,對各類型消費者提出建議,建立出以網路口碑之語意萃取為基礎的推薦系統。本研究透過文字探勘(Text Mining)技術解析網路口碑,找出影響領域的關鍵詞彙,並透過萃取出的關鍵詞彙將非結構化電子文件,透過分析轉換成機器所能解讀的資訊。以知識本體(Ontology)建立店家的知識架構,透過語意網路規則語言(SWRL)將網路口碑納入知識架構之中,並經由文件量化處理,推論出各類型優質店家,並以摘要的方式呈現店家資訊,給予消費者查詢。
Word-of-mouth is an information communication behavior resulted from transmitter and receiver face to face. This kind of commercial communication behavior is non-commercial intention.
