Shapley Value Computation in Ontology-Mediated Query Answering (Extended Abstract)

In this work, we explore the use of the Shapley value in ontology-mediated query answering (OMQA) and provide a detailed complexity analysis of Shapley value computation (SVC) in the OMQA setting. In particular, we establish a FP/#P-hard dichotomy for SVC for ontology-mediated queries (T,q) composed
