Pure basic research is experimental or theoretical work which is undertaken primarily to acquire new knowledge without a specific application in view, and is carried out without looking for long term economic or social benefits other than the advancement of knowledge. It includes most humanities research.
Strategic basic research is experimental or theoretical work which is undertaken primarily to acquire new knowledge without a specific application in view, and is directed into specific broad ares in the expectation of useful discoveries. It provides the broad base of knowledge necessary for the solution of recognised practical problems.
Applied research is original work which is undertaken to acquire new knowledge with a specific practical application in view. Applied research is undertaken to determine possible uses for the findings of basic research or to determine new methods or ways of achieving some specific and pre-determined objective.
Experimental development is systematic work, using existing knowledge gained from research and/or practical experience, for the purpose of creating new or improved materials, products, devices, processes or services. In the social sciences, experimental development may be defined as the process of transferring knowledge gained through research into operational programs.
