  • Publication number: 20050060305
    Abstract: A pharmaceutical knowledge base is provided that contains multiple information items stored in at least one computer. Pharmaceutical knowledge is represented in a multi-dimensional coordinate space having at least first, second and third axes, where the first axis pertains to diseases, the second axis pertains to targets, and the third axis pertains to drug compounds. Pharmaceutical knowledge may be mapped into the multi-dimensional coordinate space by assigning each information item one or more locations in the space, dependent upon the data contained within the information item. This mapping may then be used to reveal hitherto unappreciated connections between the axes, such as the potential use of a particular compound or target for treating a certain disease.
