Description logics (DLs) are well-known knowledge representation formalisms focused on the representation of terminological knowledge. Due to their first-order semantics, these languages (in their classical form) are not suitable for representing and handling uncertainty. A probabilistic extension of a light-weight DL was recently proposed for dealing with certain knowledge occurring in uncertain contexts. In this paper, we continue that line of research by introducing the Bayesian extension \BALC of the propositionally closed DL \ALC. We present a tableau-based procedure for deciding consistency, and adapt it to solve other probabilistic, contextual, and general inferences in this logic. We also show that all these problems remain \ExpTime-complete, the same as reasoning in the underlying classical \ALC.

  1. T-CPDL: A Temporal Causal Probabilistic Description Logic for Developing Logic-RAG Agent

    cs.AI 2025-06 reject novelty 4.0 of 10

    T-CPDL combines temporal, causal, and probabilistic operators into a Description Logic intended to support logic-enhanced RAG, but the preprint supplies only a syntax sketch and unverified theorems.
