Towards Dynamic Consistency Checking in Goal-directed Predicate Answer Set Programming
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.
AUTO-DISCERN: Autonomous Driving Using Common Sense Reasoning
That is, while machine learning technology is good for observing and automatically understanding the surroundings of an automobile, driving decisions are better automated via commonsense reasoning rather than machine learning.

We introduce a general semantics-based framework for natural language QA and also describe the SQuARE system, an application of this framework.
White-box Induction From SVM Models: Explainable AI with Logic Programming
In our new approach, however, the data-dependent hill-climbing search is replaced with a model-dependent search where a globally optimal SVM model is trained first, then the algorithm looks into support vectors as the most influential data points in the model, and induces a clause that would cover the support vector and points that are most similar to that support vector.
