One aspect of common sense reasoning is reasoning about normal
cases, e.g. a physician will first try to interpret symptoms by a
common disease, and will take more exotic possibilities only later
into account. Such "normality" can be encoded, e.g. by
a relation, where case A is considered more normal than case B.
This gives a standard semantics or interpretation to nonmonotonic
reasoning (a branch of common sense reasoning), or, more formally,
to nonmonotonic logics. We consider in this book the repercussions
such normality relations and similar
constructions have on the resulting nonmonotonic logics, i.e. which
types of logic are adequate for which kind of relation, etc.
We show in this book that some semantics correspond nicely to some
logics, but also that other semantics do not correspond to any
logics of the usual form.
Key features:
- provides a coherent picture of several formalisms of nonmonotonic
logics.
- gives completeness and incompleteness results for many variants
of preferential, distance based, and other semantics.
- gives probably the first systematic investigation of definability
preservation and its consequences.
- gives new proof techniques for completeness results.
- is centered on semantics
