this volume contains the refereed proceedings of the 13thinternationalconference on logicprogramming and nonmonotonicreasoning, lpnmr 2015, held in September 2015 in Lexington, KY, USA. the 290long and 11 short papers presented together with 3 invited talks, the paper reporting on the Answer Set programming competition, and four papers presented by lpnmr student attendees at the doctoral consortium were carefully reviewed and selected from 60 submissions. lpnmr is a forum for exchanging ideas on declarative logicprogramming, nonmonotonicreasoning, and knowledge representation. the aim of the lpnmrconferences is to facilitate interactions between researchers interested in the design and implementation of logic-based programming languages and database systems, and researchers who work in the areas of knowledge representation and nonmonotonicreasoning.

In answer set programming, two groups of rules are considered strongly equivalent if they have the same meaning in any context. Strong equivalence of two programs can be sometimes established by deriving rules of each program from rules of the other in an appropriate deductive system. this paper shows how to extend this method of proving strong equivalence to programs containing the counting aggregate.

ErgoAI (abbr. Ergo) is a high level, multi-paradigm logicprogramming language and system developed by Coherent Knowledge Systems as an enhancement of and a successor to the popular Flora-2 system. Ergo is oriented towards scalable knowledge representation and reasoning, and can exploit both structured knowledge as well as knowledge derived from external sources such as vector embeddings. From the start, Ergo (and Flora-2 before it) were designed to exploit the well-founded semantics for reasoning in a multi-paradigm environment, including object-based logic (F-logic) with non-monotonic inheritance;higher order syntax in the style of HiLog;defeasibility of rules;semantically clean transactional updates;and extensive use of subgoal delay for better logical behavior and performance. Although Ergo programs are compiled into XSB and adopt many Prolog features, Ergo is altogether a different language with functionality equivalent to major Prologs.

Answer-set programming (ASP) is a declarative logicprogramming paradigm that provides an efficient problem-solving approach in logic-based artificial intelligence (AI). While it has proven successful, ASP encounters specific situations where its language falls short of accurately representing and reasoning about incomplete information. Researchers now widely agree that ASP requires powerful introspective reasoning withthe use of epistemic modal operators;yet, despite long-lasting debates on how to extend ASP with such operators, they cannot reach a consensus on satisfactory semantics. Cabalar et al. argue that such research should be grounded in formal robustness. thus, inspired by ASP's foundational properties, they introduce a structural principle called epistemic splitting and designate it as one of the compulsory criteria for epistemic ASP. this paper generalises their approach to a more comprehensive, meticulous, and conservative extension of ASP-splitting, thereby enhancing its applicability and efficiency.

Recently forms of abstraction have been proposed for bothlogic programs (LPs) under the answer set semantics (ASP) and for the related formalism of assumption-based argumentation (ABA), e.g., via clustering of atoms or assumptions, in order to simplify a given LP or ABA framework. In both approaches after clustering the original answer sets and assumption sets are over-approximated, withthe aim of avoiding spuriousness. In contrast, in ASP a given LP is syntactically modified to achieve over-approximation, while on ABA the framework is minimally modified and the semantics is abstracted. In this work we follow the latter approach and provide a novel semantical abstraction for LPs and for ABA frameworks corresponding to LPs.

Petri nets are a class of models of computation used to compactly represent discrete event systems. Among many application domains, they have now become the most prominent formalism to express process models in Process Mining, thanks to their formal semantics that enables automated analysis techniques. In this context, model repair is the task of aligning a process model with actual executions of the process. Current solutions to model repair do not allow for embedding domain knowledge, providing guarantees of rigor, and enforcing structural requirements at the same time. In this paper, we fill this gap by proposing an approach based on the Inductive logicprogramming system ILASP. We then implement our approach and perform an experimental evaluation, showing both its expressiveness and feasibility.

Traditionally, in the argumentation theory literature structured arguments are constructed from rules interpretations aiming to build well-supported deductive evidence. Different from other approaches, we emphasize the role of investigating general frameworks that can also provide a consistent and well-defined justification for a conclusion that cannot be inferred and there is certainty about it, which we call here NAF-arguments, which have been less explored in the formal argumentation theory, despite its potential use in practical applications for building nuanced well-structured explanations and justifications. this article introduces the so-called semantic argumentation guaranteeing well-known principles for quality in structured argumentation, and withthe ability to generate two types of arguments, those where the conclusion atoms are semantically interpreted as true, and those where the conclusion is assumed to be false, we call them here semantic and NAF-arguments respectively. this framework is defined on the set of all logic programs in terms of rewriting systems based on a confluent set of transformation rules, the so-called Confluent logicprogramming Systems, making this approach a general framework. Additionally, we introduce a method for building such arguments using the program's strata through partial interpretations. We implement our framework named semantic argumentation solver available open source.

Connections of intuitionistic and intermediate logics withlogicprogramming have been extensively studied in the literature. Among the different results in the literature we find equilibrium logic (Pearce, 1996) and Safe beliefs (Osorio et al., 2005). Pearce's approach admits a characterisation in terms of a fixpoint (consequence) operator on the here-and-there intermediate logic (Heyting, 1930), which is similar to the notion of theory completion in default and autoepistemic logics. Osorio's safe beliefs are also given in terms of a fixpoint operator under intuitionistic logic semantics. In this latter case, intuitionistic logic can be replaced by any intermediate logic without altering the result. In this paper we consider temporal equilibrium logic, an combination of equilibrium logic and linear-time temporal logic. In this context we extend Pearce's and Osorio's approach to temporal case and we discuss the relation of intuitionistic temporal logic and temporal logicprogramming.
