Conditionals are fascinating and versatile objects of knowledge
representation. On the one hand, they may express rules in a very
general sense, representing, for example, plausible relationships,
physical laws, and social norms. On the other hand, as default
rules or general implications, they constitute a basic tool for
reasoning, even in the presence of uncertainty. In this sense,
conditionals are intimately connected both to information and
inference. Due to their non-Boolean nature, however, conditionals
are not easily dealt with. They are not simply true or false -
rather, a conditional "if A then B" provides a context, A, for B to
be plausible (or true) and must not be confused with "A entails B"
or with the material implication "not A or B." This ill- trates how
conditionals represent information, understood in its strict sense
as reduction of uncertainty. To learn that, in the context A, the
proposition B is plausible, may reduce uncertainty about B and
hence is information. The ab- ity to predict such conditioned
propositions is knowledge and as such (earlier) acquired
information. The ?rst work on conditional objects dates back to
Boole in the 19th c- tury, and the interest in conditionals was
revived in the second half of the 20th century, when the emerging
Arti?cial Intelligence made claims for appropriate
formaltoolstohandle"generalizedrules."Sincethen,conditionalshavebeenthe
topic of countless publications, each emphasizing their relevance
for knowledge representation, plausible reasoning, nonmonotonic
inference, and belief revision.
Ausgehend von der Informationstheorie untersucht und bewertet
Friedhelm Kulmann fur die Betriebswirtschaftslehre spezielle
Methoden der Wissensverarbeitung und setzt probabilistische
Konzepte zur Vorbereitung unternehmerischer Entscheidungen ein.
Seine Methode veranschaulicht er am Beispiel von Anfragebewertungen
aus dem Bereich Industriegutermarketing."
