Third Workshop on Epistemic Extensions of Logic Programming

Several successful logic programming languages, evidenced by the availability of a multitude of solvers, industrial applications, and an active research community, have been proposed in the literature. Researchers have long recognized the need for epistemic operators in these languages. This led to a flurry of research on this topic, and renewed interest in recent years. A central question is that of the definition of a rigorous and intuitive semantics for such epistemic operators, which is still subject of ongoing research. Notions of equivalence, structural properties, and the inter-relationships between logic programming languages and established logics are all subjects being actively investigated. Another important topic is that of practical solvers to compute answers to logic programs that contain epistemic operators. Several solvers are actively developed, building on established solvers, or using rewriting-based approaches. For practical applications, additional language features are actively explored in order to be able to apply epistemic extensions of logic programming langauges to practical problems. The goal of this workshop is to facilitate discussions regarding these topics and a productive exchange of ideas.
