In the field of automated planning, an action is called reversible when other actions can be applied in order to revert the effects of this action and return to the original state. In recent years, there has been rene...

In this paper, we present an argument-based mechanism to generate hypotheses about belief-desire-intentions on dynamic and complex activities of a software agent. We propose to use a composed structure called activity as unit for agent deliberation analysis, maintaining actions, goals and observations of the world always situated into a context. Activity transformation produces changes in the knowledge base activity structure as well in the agent's mental states. For example, in car driving as a changing activity, experienced and novice drivers have a different mental attitudes defining distinct deliberation processes withthe same observations of the world. Using a framework for understanding activities in social sciences, we endow a software agent withthe ability of deliberate, drawing conclusion about current and past events dealing with activity transformations. An argument-based deliberation is proposed which progressively reason about activity segments in a bottom-up manner. Activities are captured as extended logic programs and hypotheses are built using an answer-set programming approach. We present algorithms and an early-stage implementation of our argument-based deliberation process.
One of the most difficult problems in Artificial Intelligence is related to acquiring commonsense knowledge - to create a collection of facts and information that an ordinary person should know. In this work, we prese...

In this work, the notion of provability for first order linear temporal logic over finite time structures, FO-LTLfin, is studied. We show that the validity problem for such a logic is not recursively enumerable, hence FO-LTLfin is not recursively axiomatizable. this negative result however does not hold in the case of bounded validity, that is truth in all temporal models where the object domain is possibly infinite, but the underlying sequence of time points does not exceed a given size. A formula is defined to be A-valid if it is true in all tempered models whose underlying time frtime is not greater them κ, where κ is any fixed positive integer. In this work a tableau calculus is defined, that is sound and complete with respect to κ-validity, when given as input the initial formula and the bound κ on the size of the temporal models. the main feature of the system, extending the prepositional calculus defined in [7], is that of explicitly denoting time points and having tableau nodes labelled by either expressions intuitively stating that a formula holds in a given temporal interval or "temporal constraints" i.e. linear inequalities on time points. Branch closure is reduced to unsatisfiability over the integers of the set of temporal constraints in the branch.
Linked Data principles allow for processing SPARQL queries on-the-fly by dereferencing URIs. Link-traversal query approaches for Linked Data have the benefit of up-to-date results and decentralised execution, but oper...

How to comprehensively, clearly, and accurately obtain the electromagnetic characteristics and relations of planning objects is an important issue in realizing efficient and flexible electromagnetic spectrum planning. In this paper, we use knowledge Graph, an intelligent technology in Semantic Web research, to construct the knowledge graph ontology of frequency equipment. We use the reasoning structure based on OWL + SWRL + Jess, combined withthe OWL API to construct reasoning rules and procedures to complete the knowledge service required for system-level electromagnetic spectrum planning by setting up specific scenarios.
In 1969, Tarski asked whether the arithmetic identities taught in high school are complete for showing all arithmetic equations valid for the natural numbers. We know the answer to this question for various subsystems...
