In our framework, we show how counterfactual explanations are computed and justified by imagining worlds where some or all factual assumptions are altered/changed.

We propose to use s(CASP), a top-down execution model for predicate ASP, to model vague concepts following a set of patterns.

Our approach utilizes answer set programming and the s(CASP) goal-directed ASP system.

To the best of our knowledge, AutoConcierge is the first automated conversational agent that can realistically converse like a human and provide help to humans based on truly understanding human utterances.

However, the performance of existing s(CASP) implementations is not on par with other ASP systems: model consistency is checked once models have been generated, in keeping with the generate-and-test paradigm.

We also show how answer set programming (ASP) and its query-driven implementation s(CASP) can be used to directly realize the event calculus model of the requirements.

Automated commonsense reasoning is essential for building human-like AI systems featuring, for example, explainable AI.

The resulting model, s(CASP), can constrain variables that, as in CLP, are kept during the execution and in the answer sets.
