Uncertainty in Description Logics: a Lattice-based Approach
نویسنده
چکیده
It is generally accepted that knowledge based systems would be smarter if they can manage uncertainty. In this paper we extend Description Logics, well-known logics for managing structured knowledge, towards the management of uncertainty. We allow to express that a sentence is not just true or false, but certain to some degree, which is taken from a certainty lattice.

Uncertainty and Description Logic Programs over Lattices
It is generally accepted that knowledge based systems would be smarter if they can manage uncertainty. In this paper we extend Description Logics, well-known logics for managing structured knowledge, towards the management of uncertainty. We allow (i) to express that a sentence is not just true or false, but certain to some degree, which is taken from a certainty lattice; and (ii) combine the l...
متن کاملDesign of An Intelligent Model for Strategic Planning in Mineral Holding: Case study, Shahab-Sang Holding
Business logic is one of the most important logics based on the decision matrix. However, using this logic alone and environmental uncertainty leads to problems such as low accuracy and integrity in strategic planning. In this work, we use an intelligent model based on the neural-fuzzy approach aiming at a desired decision-making and reducing the uncertainty in the strategic planning in mineral...
متن کاملFutures studies of hospital resilience supply chain with the intuitive logics scenario planning
Background: Scenario planning is one of the most crucial future study methods in uncertain and complex situations. Hospital supply chain resilience also requires an understanding of future events due to the complexity of relationships and exposure to unexpected circumstances. The purpose of this study is to formulate scenarios for the future development of hospital supply chain resilience. Mat...
متن کاملEQ-logics with delta connective
In this paper we continue development of formal theory of a special class offuzzy logics, called EQ-logics. Unlike fuzzy logics being extensions of theMTL-logic in which the basic connective is implication, the basic connective inEQ-logics is equivalence. Therefore, a new algebra of truth values calledEQ-algebra was developed. This is a lower semilattice with top element endowed with two binary...
متن کاملDescription Logics over Lattices
In the last decade a substantial amount of work has been carried out in the context of Description Logics (DLs). DLs are a logical reconstruction of the so-called framebased knowledge representation languages, with the aim of providing a simple wellestablished Tarski-style declarative semantics to capture the meaning of the most popular features of structured representation of knowledge. A main...
