abstract = {Logic Programs with Annotated Disjunctions (LPADs) allow
to express probabilistic information in logic programming. The semantics
of an LPAD is given in terms of well founded models of the normal logic
programs obtained by selecting one disjunct from each ground LPAD
clause. The paper presents SLGAD resolution that computes the (con-
ditional) probability of a ground query from an LPAD and is based on
SLG resolution for normal logic programs. The performances of SLGAD
are evaluated on classical benchmarks for normal logic programs under
the well founded semantics, namely the stalemate game and the ancestor
relation. The results show that SLGAD has good scaling properties and
is able to deal with cyclic programs.},

Complex and flexible business processes are critical not only
because they are difficult to handle, but also because they often
tend to be less intelligible. Monitoring and verifying complex and
flexible processes becomes therefore a fundamental requirement. We
propose a framework for performing compliance checking of process
execution traces w.r.t.~expressive reactive business rules, tailored
to the MXML meta-model. Rules are mapped to (extensions of) Logic
Programming, to the aim of providing both monitoring and
a-posteriori verification capabilities. We show how different rule
templates, inspired by the ConDec language, can be easily specified
and then customized in the context of a real industrial case study.
We finally describe how the proposed language and its underlying
a-posteriori reasoning technique have been concretely implemented as
a ProM analysis plug-in.},

abstract = {Logic Programs with Annotated Disjunctions (LPADs) provide a simple
and elegant framework for representing probabilistic knowledge in logic programming.
In this paper we consider the problem of learning ground LPADs starting from a set of
interpretations annotated with their probability. We present the system ALLPAD for
solving this problem. ALLPAD modifies the previous system LLPAD in order to tackle
real world learning problems more effectively. This is achieved by looking for an
approximate solution rather than a perfect one. A number of experiments have been
performed on real and artificial data for evaluating ALLPAD, showing the feasibility
of the approach},

abstract = {The management of business processes has recently received a lot of attention. One of the most interesting problems is the description of a process model in a language that allows the checking of the compliance of a process execution (or trace) to the model. In this paper we propose a language for the representation of process models that is inspired to the SCIFF language and is an extension of clausal logic.
A process model is represented in the language as a set of integrity constraints that allow conjunctive formulas as disjuncts in the head.
We present an approach for inducing these models from data: we define a subsumption relation for the integrity constraints, we define a refinement operator and we adapt the algorithm ICL to the problem of learning such formulas. The system has been applied to the problem of inducing the model of a sealed bid auction and of the NetBill protocol. The data used for learning and testing were randomly generated from correct models of the processes.},
