Allocation of research funding is based on changes to sizes of resource clusters. Each resource cluster is composed of a set of researchers devoted to a single aspect of a research field. A size change to a specific resource cluster indicates a change to a level of activities associated with a corresponding specific aspect of the research field. In response to identifying an under-attended aspect of the research field caused by the change in sizes of the resource clusters, a recommendation is issued to allocate additional funding for research to the under-attended aspect of the research field.
