Applications Of Paraconsistency In Data And Knowledge Bases
نویسندگان
چکیده
The study of paraconsistent logic as a branch of mathematics and logic has been pioneered by Newton da Costa. With the growing advent of distributed and often inconsistent databases over the last ten years, there has been growing interest in paraconsistency amongst researchers in databases and knowledge bases. In this paper, we provide a brief survey of work in paraconsistent databases and knowledge bases affected by Newton da Costa’s important and lasting contributions to the field.

Extending Paraconsistent SROIQ
The four-valued paraconsistent logic SROIQ4, originally presented by Ma and Hitzler, is extended to incorporate additional elements of SROIQ. It is shown that the modified logic is classically sound and that its embedding into classical SROIQ is consequence preserving. Furthermore, inserting special axioms into a SROIQ4 knowledge base allows additional nontrivial conclusions to be drawn, withou...
متن کاملA Local Approach to Reasoning under Incosistency in Stratified Knowledge Bases
This paper investigates an approach for reasoning under inconsistency in a "local" way, in prioritized knowledge bases. In such bases, the higher the layer, the more certain, the more reliable are the formulas stored in this layer. The proposed approach is based on the notion of (consistent) argument whose strength depends on the layer of the least certain formulas involved in the argument. Eac...
متن کاملArgumentative inference in uncertain and inconsistent knowledge bases
This paper presents and discusses several methods for reasoning from inconsistent knowledge bases. A so-called argumentative-consequence relation, taking into account the existence of consistent arguments in favor of a conclusion and the absence of consistent arguments in favor of its contrary, is particularly investigated. Flat knowledge bases, i.e. without any priority between their elements,...
متن کاملParaconsistency in hybrid logic
As in standard knowledge bases, hybrid knowledge bases (i.e., sets of information specified by hybrid formulas) may contain inconsistencies arising from different sources, namely from the many mechanisms used to collect relevant information. Being a fact, rather than a queer anomaly, inconsistency also needs to be addressed in the context of hybrid logic applications. This paper introduces a pa...
متن کاملParaconsistent OWL and related logics
The Web Ontology Language OWL is currently the most prominent formalism for representing ontologies in Semantic Web applications. OWL is based on description logics, and automated reasoners are used to infer knowledge implicitly present in OWL ontologies. However, because typical description logics obey the classical principle of explosion, reasoning over inconsistent ontologies is impossible i...
