本研究依據本體理論、本體發展方法論與知識轉換模式,建構汽車引擎故障診斷知識本體的模型,以及語意查詢系統。首先蒐集國內外相關文獻,探討汽車引擎系統最常出現之故障現象與故障原因,並藉由深度訪談與專家會議,發掘汽車修護專家的內隱知識,完成汽車引擎系統故障分析表;再配合本體理論文獻探討的結果,建構以知識本體為基礎的汽車引擎故障診斷的框架體系,建置於美國史丹福大學所開發之protégé公共軟體,並建構出一個語意查詢系統,藉由建立汽車引擎故障診斷的知識本體,以及隱含查詢語法之網頁表單查詢介面,使用者能夠透過簡單的查詢步驟,獲得汽車引擎故障現象的故障原因及排序順位。 本研究發展出之汽車引擎故障診斷知識本體,主要是基於應用上的需求,可作為汽車消費者學習與了解汽車引擎故障診斷的知識平台,學校實施問題導向教學之數位學習教材,並與企業資訊系統結合,提供專家知識以提升車廠接待人員問診判斷之能力、維修技師之專業能力。
The purpose of this study was to construct an automotive engine fault diagnosis ontology model and a semantic search system based on ontology theory, building method and knowledge transfer pattern. In order to establish an engine system fault tree analysis diagram, this study explored the literature that is related to significant phenomenons and causes of engine failures through in-depth interviews and expert consultations to excavate implicit knowledge from an automotive repair and maintenance expert system. This paper presents basic automotive engine fault diagnosis frame for building ontology, which should enable using protégé on the semantic web. Users are provided simple and convenient steps when performing a diagnosis due to structured query language which are comprised of available protégé model descriptions and the query form interface search system of web pages. The described ontology guidelines are based on user needs that can be used to set up a platform for evaluation and application in the automobile industry or a technical school. The research study is expected to help students proceed problem-based learning and enhance technicians’ problem solving abilities.
