We present the web application "cplint on SWISH", that allows the user
to write probabilistic logic programs and compute the probability of queries
with just a web browser. The application is based on SWISH, a recently
proposed web framework for logic programming. SWISH is based on various
features and packages of SWI-Prolog, in particular its web server and
its Pengine library, that allow to create remote Prolog engines and to pose
queries to them. In order to develop the web application, we started from
the PITA system which is included in cplint, a suite of programs for reasoning
on Logic Programs with Annotated Disjunctions, by porting PITA
to SWI-Prolog. Moreover, we modified the PITA library so that it can be
executed in a multi-threading environment. Developing "cplint on SWISH"
also required modification of the JavaScript SWISH code that creates and
queries Pengines. "cplint on SWISH" includes a number of examples that
cover a wide range of domains and provide interesting applications of Probabilistic
Logic Programming (PLP). By providing a web interface to cplint
we allow users to experiment with PLP without the need to install a system,
a procedure which is often complex, error prone and limited mainly to the
Linux platform. In this way, we aim to reach out to a wider audience and
popularize PLP.},

abstract = {Probabilistic logic models are used ever more often to deal with
the uncertain relations typical of the real world.
However, these models usually require expensive inference procedures. Very recently the problem of identifying tractable
languages has come to the fore.
In this paper we consider the models used by the learning from interpretations
ILP setting, namely
sets of integrity constraints, and propose a probabilistic version
of them. A semantics in the style of the distribution semantics is adopted, where each integrity constraint is annotated with a probability.
These probabilistic constraint logic models assign a probability of being positive to interpretations. This probability can be computed
in a time that is logarithmic in the
number of ground instantiations of violated constraints.
This formalism can be used as the target language in learning systems and
for declaratively specifying the behavior of a system.
In the latter case, inference corresponds to computing the probability of compliance
of a system's behavior to the model.

title = {Probabilistic Hybrid Knowledge Bases under the Distribution
Semantics},
author = {Marco Alberti and Evelina Lamma and Fabrizio Riguzzi and Riccardo Zese},
abstract = {Since Logic Programming (LP) and Description Logics (DLs) are based on
different assumptions (the closed and the open world assumption,
respectively), combining them provides higher expressiveness in
applications that require both
assumptions.
Several proposals have been made to combine LP and DLs. An especially
successful line of research is the one based on the Lifschitz's
logic of Minimal Knowledge with Negation as Failure (MKNF). Motik
and Rosati introduced Hybrid knowledge bases (KBs), composed of LP
rules and DL axioms, gave them an MKNF semantics and
studied their complexity. Knorr et al. proposed a well-founded semantics for
Hybrid KBs where the LP clause heads are non-disjunctive, which
keeps querying polynomial (provided the underlying DL is polynomial)
even when the LP portion is non-stratified.
In this paper, we propose Probabilistic Hybrid Knowledge Bases (PHKBs),
where the atom in the head of LP clauses and each DL axiom is
annotated with a probability value. PHKBs are given a distribution
semantics by defining a probability distribution over deterministic
Hybrid KBs. The probability of a query being true is the sum of the
probabilities of the deterministic KBs that entail the query. Both
epistemic and statistical probability can be addressed, thanks to
the integration of probabilistic LP and DLs.},

abstract = {
The management of business processes can support efficiency improvements in organizations. One of the most interesting problems is the mining and representation of process models in a declarative language.
Various recently proposed knowledge-based languages showed advantages over graph-based procedural notations.
Moreover, rapid changes of the environment require organizations to check how compliant are new process instances with the deployed models.
We present a Statistical Relational Learning approach to Workflow Mining that takes into account both flexibility and uncertainty in real environments.
It performs automatic discovery of process models expressed in a probabilistic logic.
It uses the existing DPML algorithm for extracting first-order logic constraints from process logs. The constraints are then translated into Markov Logic to learn their weights.
Inference on the resulting Markov Logic model allows a probabilistic classification of test traces, by assigning them the probability of being compliant to the model.
We applied this approach to three datasets and compared it with DPML alone, five Petri net- and EPC-based process mining algorithms and Tilde.
The technique is able to better classify new execution traces, showing higher accuracy and areas under the PR/ROC curves in most cases.
