中醫在長時間的歷史中,發展出「辨證論治」的特殊診治方式。透過四診─望、聞、問、切的方法診察病情,依據四診獲得的疾病資訊進行分析及判斷,即辨證;最後由辨證的資訊,確立治療方式,即為「論治」。 由於中醫辨證體系的龐雜,我們計畫運用計算機龐大的記憶能力及迅速的分析能力,研製一個中醫自動辨證系統,提供研究中醫辨證體系的平台。然而在中醫發展的過程中,因為時代背景、氣候、派別、習慣等因素,使得在古籍及文獻中充滿不同的症狀字詞及描述。沒有標準化的症狀字詞導致系統在辨證上難以作精確的判斷與區分。 因此我們先研製一個中醫症狀字詞庫,以解決中醫症狀字詞的標準化,未來可進一步作為中醫自動辨證系統的基礎建設。我們透過建立中醫症狀知識本體,來定義標準症狀,並建立症狀、症狀物件與症狀屬性之間的關係,使得標準症狀滿足一詞一義的標準。不過,一個中醫症狀字詞庫必須經過長期的使用與修訂,才會漸趨正確與完整。這個中醫症狀知識本體的建立,也能夠提供其他中醫資訊系統運用中醫症狀字詞做更有系統地分析、推論與管理。
Through the evolution of Traditional Chinese medicine for a long period of time, a special approach, called syndrome differentiation and treatment, for the diagnosis and therapy of diseases is developed. In syndrome differentiation, the doctors first analyze and differentiate properties of diseases, called syndromes, including causes, locations, and mechanisms of diseases, based on the symptoms collected from four examinations: inspection, listening and smelling, inquiry, and palpation. In syndrome treatment, the doctors then determine the principles of treatment according to differentiated syndromes. Since the system of syndrome differentiation is very huge and complex, we plan to utilize the huge memorizing capability and the speedy analyzing capability of computers to develop an automatic syndrome differentiation system to provide a platform for the research of the system of syndrome differentiation. However, during the evolution of traditional Chinese medicine, there exist various symptom terminologies and descriptions in books and literatures due to different backgrounds, climates, factions, habits, etc. The lack of standardization of symptom terminologies and descriptions makes it difficult to achieve precise analysis and differentiation of syndromes in an automatic syndrome differentiation system. Hence, we first develop a traditional Chinese medicine symptom thesaurus to solve the lack of standardization of symptom terminologies and descriptions. This symptom thesaurus can provide an infrastructure for an automatic syndrome differentiation system in the future. In this symptom thesaurus, we develop symptom ontology for traditional Chinese medicine. In this symptom ontology, we define standard symptoms, and establish the relationships between symptoms and symptom objects, and the relationships between symptoms and symptom properties so that each standard symptom represents a basic symptom and each basic symptom is represented by a unique standard symptom. However, symptom ontology must go through applications and modifications for a long period of time in order to gradually become correct and complete. By utilizing this symptom ontology, other traditional Chinese medicine information systems may perform analysis, inference and management in a more systematic way.
