One result from this work is that the well-founded semantics can formally be understood as a stratified version of Fitting (or Kripke Kleene) semantics. The construction leading to this result, however, show a certain asymmetry which is not readily understood. We will study this situation here with the result that we will obtain a coherent picture of relations between different semantics.10aKripke Kleene semantics10alogic programming10aprogramming semantics1 aHitzler, Pascal uhttp://knoesis.wright.edu/node/1633
