This paper proposes two probabilistic extensions of variants of the OWL Lite description language, which are essential for advanced applications like information retrieval. The first step follows the axiomatic approach of combining description logics and Horn clauses: Subsets of OWL Lite are mapped in a sound and complete way onto Horn predicate logics (Datalog variants). Compared to earlier approaches, a larger fraction of OWL Lite can be transformed by switching to Datalog with equality in… 

Tractable Reasoning with Bayesian Description Logics

TLDR
This paper presents a probabilistic generalization of the DL-Litedescription logics, which is based on Bayesian networks, and shows that satisfiability checking and answering unions of conjunctive queries in the new logics can be done in LogSpace in the data complexity.

Inference in Probabilistic Ontologies with Attributive Concept Descriptions and Nominals

This paper proposes a probabilistic description logic that combines (i) constructs of the well-known ALC logic, (ii) probabilistic assertions, and (iii) limited use of nominals. We start with our

This work surveys existing proposals for extending semantic web languages or formalisms underlying Semantic Web languages in terms of their expressive power, reasoning capabilities as well as their suitability for supporting typical tasks associated with the Semantics Web.

Tightly integrated probabilistic description logic programs for representing ontology mappings

TLDR
This work defines the language, and it is shown that it can be used to resolve inconsistencies and merge mappings from different matchers based on the level of confidence assigned to different rules, and shows that the well-founded semantics approximates the answer set semantics.

It is shown how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules and ontologies and define a new intermediate knowledge representation contained within this intersection: Description Logic Programs (DLP), and the closely related Description Horn Logic (DHL).
