The Castle of Ferrara (Castello Estense)


Probabilistic logic programming (PLP) approaches have received much attention in this century. They address the need to reason about relational domains under uncertainty arising in a variety of application domains, such as bioinformatics, the semantic web, robotics, and many more. Developments in PLP include new languages that combine logic programming with probability theory as well as algorithms that operate over programs in these formalisms.

PLP is part of a wider current interest in probabilistic programming. By promoting probabilities as explicit programming constructs, inference, parameter estimation and learning algorithms can be run over programs which represent highly structured probability spaces. Due to logic programming's strong theoretical underpinnings, PLP is one of the more disciplined areas of probabilistic programming. It builds upon and benefits from the large body of existing work in logic programming, both in semantics and implementation, but also presents new challenges to the field.

This workshop aims to bring together researchers in all aspects of probabilistic logic programming, including theoretical work, system implementations and applications. Interactions between theoretical and applied minded researchers are encouraged. The presence of this workshop at ILP is intended to encourage collaboration with researchers from the field of Inductive Logic Programming.

PLP: a brick to build your own starship

When one thinks about what she/he needs to fully represent and work with the domain she/he wants to model, it is not always easy to determine which approach would be the best to use. One could have to cope with uncertainty, different closure assumptions, large amount of data. For these reasons, in the last years, the combination of different technologies has achieved an exponentially increasing attention. Many researchers have focused on the combination of (probabilistic) logic programming with other formalisms, using it as a component to build more powerful approaches, which pave the way to the management of domains that are too complex to handle with the current technologies alone. In this talk, we will take an overview of some of these proposals. Especially, we will focus on the combination of probabilistic logic programming with description logics, to combine both open and closed world assumption.
