On Properties of Update Sequences Based on Causal Rejection

  title={On Properties of Update Sequences Based on Causal Rejection},
  author={Thomas Eiter and Michael Fink and Giuliana Sabbatini and Hans Tompits},
In this paper, we consider an approach to update nonmonotonic knowledge bases represented as extended logic programs under the answer set semantics. In this approach, new information is incorporated into the current knowledge base subject to a causal rejection principle, which enforces that, in case of conflicts between rules, more recent rules are preferred and older rules are overridden. Such a rejection principle is also exploited in other approaches to update logic programs, notably in the… CONTINUE READING
