Concept origins and post-MELODI investigations. MELODI takes two concepts and derives intermediates. These concepts (solid lines) can originate from a number of places, e.g. an epidemiological observation, or a finding from a laboratory experiment. By creating article sets that represent these two concepts, potential intermediates (dashed lines) can be derived which may provide testable hypotheses. These can then be investigated further using approaches similar to those that created the initial concepts.
