以本體為基礎建構營養照護知識模型─以慢性腎臟病為例
An Ontology-Based Knowledge Model of Nutrient Care─A Case Study for Chronic Kidney Disease
摘要
本研究提出一個針對慢性腎臟病患者的營養照護知識模型，根據全國腎臟基金會研究顯示，大部分的病患並不能夠調整自己的飲食，本研究將整合各領域異結構的知識源，並利用知識庫系統作為問題解決，藉由知識模型為核心的設計，包括：(1) 建置「領域本體」為共用的知識概念，使用is-a關係來表達的實例知識的分類架構，並提供標準術語讓本體之間溝通；(2) 建置物件導向的知識框架為「任務本體」，使用has-a關係來表達問題組成；以及(3) 針對問題解決與計算式「開發語意規則」邏輯以提供推論引擎運算。最後，本研究從醫療機構取得慢性腎臟病患者的基本資料做為實驗對象，已完成十位患者的實驗結果，實驗顯示此知識模型符合實務上營養照護之計算原則。

This study proposes a knowledge model of nutrient care especially for chronic kidney disease. According to national kidney foundation reports, most patients are incapable to adjust their proper dietary plan. This study will integrate the different structure of the source domain knowledge, and uses knowledge-based system development as a solution. With the knowledge model as the core of design, the system includes: First, a Domain Ontology for establishing common knowledge concepts and instances using is-a relations to express the knowledge categorization structure and to provide a standard terminology set for ontology communication; Second, a Task Ontology to establish an objective-oriented knowledge framework using has-a relations to express the combination of questions; and Third, Semantic Rules to develop the logical steps for problem solving and the computation rules for inference engine computation. Finally, this study obtaining basic information about chronic kidney disease patients as experimental subjects from medical institutions, the experiments results have been completed ten patients, and show that it is in line with pragmatic way to computing of nutrition care principles.
