In biomedical research area, various researches have been carried out to develop novel tools for analyzing biomedical interactions and relationships between compounds, proteins, genes, and diseases. In previous project, we built network of biomedical information related to herbal medicine and developed multidimensional analysis tools exploiting those relationship between data. However the previous system is not capable of building network of traditional medical knowledge of herbal medicine and analyzing it. In this paper, therefore, we aimed to expand the previous system by adopting traditional Korean medical knowledge. In order to design the expanded system, we analyzed the process of building network and user interfaces of the previous system as well as the database schema related to herbal medicine in traditional Korean medicine information portal (OASIS). The expanded system has two sided view of network. In the left side of view, there is traditional medical knowledge based network which is composed of herbal medicine, herbal prescription, efficacy, and target and provides links to the web contents of papers, prescriptions, monographs, and specimen of OASIS. The expanded K-herb network multidimensional analysis system by connecting traditional medical knowledge will be a useful network analysis tool to researchers in the traditional medical and biomedical area.
