We in this paper have constructed herb and formula ontologies. Herb instances and formula instances can be distinguished by nature, used part, effect, disease pattern, symptom, and formula and constituent herb, dosage, effect, disease pattern, symptom, and medical book, respectively. The knowledge for herbs and formulas in ontology is formalized with the distinguishable elements and their relations. Based on the herb and formula ontologies, we propose the three reasoning rules as follows: In herb ontology, the relation between herb and disease can be reasoned if there are the relation between herb and effect, and effect and disease. In formula ontology, there are two reasoning rules. First, if each constituent herb, dosage, effect, disease pattern, and symptom of two formulas is same, it can be reasoned that two formulas are same though the medical books of the formulas are different. Second, if each constituent herb and dosage is same in two formula, it can be reasoned that each formula has all of effects, disease patterns, and symptoms of formulas. In future study, we study other ontologies such as disease ontology with respect to Korean Medicine and define the reasoning rules about the ontologies.

본 연구에서는 다양한 Open API를 이용한 매쉬업 검색서비스를 통해 한의 분야의 약재 정보를 검색하는 약재 검색 매쉬업 시스템을 구축하였다. 특히 본 논문에서는 일반적인 Open API외에도 현재 서비스되고 있는 한의 분야의 논문과 연구개발과제 서비스에 대한 2개의 Open API를 개발하고 공개하여 전문적인 지식을 쉽게 공유하고 검색할 수 있도록 하였다. 한의 분야의 약재 정보는 다른 분야와는 다르게 정보의 출전이 어디냐에 따라 다양한 이름과 설명들을 가지기 때문에 일반적인 검색 방법과 같이 한 두 개의 검색어를 이용해서는 원하는 검색 결과를 얻기 힘들다. 본 연구에서는 이러한 문제를 해결하기 위해서 기존에 한의 약재 100건의 정보를 온톨로지로 구축한 약재 온톨로지를 이용해서 검색어를 확장하고 이를 여러 Open API를 통해 검색하는 시스템을 구축함으로써 정확하고 포괄적인 검색이 이루어질 수 있도록 하였다.

Knowledge which is represented by formal logic are widely used in many domains such like artificial intelligence, information retrieval, e-commerce and so on. And for medical field, medical documentary records retrieval, information systems in hospitals, medical data sharing, remote treatment and expert systems need knowledge representation technology. To retrieve information intellectually and provide advanced information services, systematically controlled mechanism is needed to represent and share knowledge. Importantly, medical expert's knowledge should be represented in a form that is understandable to computers and also to humans to be applied to the medical information system supporting decision making. And it should have a suitable and efficient structure for its own purposes including reasoning, extendability of knowledge, management of data, accuracy of expressions, diversity, and so on. we call it ontology which can be processed with machines. We can use the ontology to represent traditional medicine knowledge in structured and systematic way with visualization, then also it can also be used education materials. Hence, the authors developed an Shanghanlun ontology by way of showing an example, so that we suggested a methodology for ontology development and also a model to structure the traditional medical knowledge. And this result can be used for student to learn Shanghanlun by graphical representation of it's knowledge. We analyzed the text of Shanghanlun to construct relational database including it's original text, symptoms and herb formulars. And then we classified the terms following some criterion, confirmed the structure of the ontology to describe semantic relations between the terms, especially we developed the ontology considering visual representation. The ontology developed in this study provides database showing fomulas, herbs, symptoms, the name of diseases and the text written in Shanghanlun. It's easy to retrieve contents by their semantic relations so that it is convenient to search knowledge of Shanghanlun and to learn it. It can display the related concepts by searching terms and provides expanded information with a simple click. It has some limitations such as standardization problems, short coverage of pattern(證), and error in chinese characters input. But we believe this research can be used for basic foundation to make traditional medicine more structural and systematic, to develop application softwares, and also to applied it in Shanghanlun educations.

Anethole and garlic have an immune modulatory effects on avian coccidiosis, and these effects are correlated with gene expression changes in intestinal epithelial lymphocytes (IELs). In this study, we integrated gene expression datasets from two independent experiments and investigated gene expression profile changes by anethole and garlic respectively, and identified gene expression signatures, which are common targets of these herbs as they might be used for the evaluation of the effect of plant herbs on immunity toward avian coccidiosis. We identified 4,382 and 371 genes, which were differentially expressed in IELs of chickens supplemented with garlic and anethole respectively. The gene ontology (GO) term of differentially expressed genes (DEGs) from garlic treatment resulted in the biological processes (BPs) related to proteolysis, e.g., "modification-dependent protein catabolic process", "proteolysis involved in cellular protein catabolic process", "cellular protein catabolic process", "protein catabolic process", and "ubiquitin-dependent protein catabolic process". In GO analysis, one BP term, "Proteolysis", was obtained. Among DEGs, 300 genes were differentially regulated in response to both garlic and anethole, and 234 and 59 genes were either up- or down-regulated in supplementation with both herbs. Pathway analysis resulted in enrichment of the pathways related to digestion such as "Starch and sucrose metabolism" and "Insulin signaling pathway". Taken together, the results obtained in the present study could contribute to the effective development of evaluation system of plant herbs based on molecular signatures related with their immunological functions in chicken IELs.
