| Descripción |
. We present a new approach to probabilistic logic programs
with a possible worlds semantics. Classical program clauses
are extended by a subinterval of [0; 1] that describes the range for
the conditional probability of the head of a clause given its body.
We show that deduction in the defined probabilistic logic programs
is computationally more complex than deduction in classical logic
programs. More precisely, restricted deduction problems that are Pcomplete
for classical logic programs are already NP-hard for probabilistic
logic programs. We then elaborate a linear programming approach
to probabilistic deduction that is efficient in interesting special
cases. In the best case, the generated linear programs have a number
of variables that is linear in the number of ground instances of
purely probabilistic clauses in a probabilistic logic program.

There is already a quite extensive literature on probabilistic propositional
logics and their various dialects. The most fa...
