Knowledge Reductions in Inconsistent Information Systems Based on Dominance Relations
نویسنده
چکیده
Knowledge reduction is one of the most important problems in rough set theory. However, most of information systems are not only inconsistent, but also based on dominance relations because of various factors. To acquire brief decision rules from inconsistent systems based on dominance relations, knowledge reductions are needed. The main aim of this paper is to study the problem. The assignment reduction and approximation reduction are introduced in inconsistent systems based on dominance relations and relationship between them are examined. The judgment theorem and discernibility matrix are obtained, from which we can provide an approach to knowledge reductions in inconsistent systems based on dominance relation.

Knowledge reduction and matrix computation in inconsistent ordered information systems
Abstract: In this article, assignment reduction and approximation reduction are proposed for Inconsistent Ordered Information Systems (IOIS). The properties and relationships between assignment reduction and approximation reduction are discussed. The dominance matrix and decision assignment matrix are also proposed for information systems based on dominance relations. The algorithm of assignmen...
متن کاملMethods for knowledge reduction in inconsistent ordered information systems
Knowledge reduction is one of the most important problems in the study of rough set theory. However, in real-world, most of information systems are based on dominance relations in stead of the classical equivalence relation because of various factors. The ordering of properties of attributes plays a crucial role in those systems. To acquire brief decision rules from the systems, knowledge reduc...
متن کاملAssignment Reductions in Inconsistent Ordered Intuition Fuzzy Infor- mation Decision Tables
In the real-world, most information systems are based on dominance relations and may be inconsistent. Moreover, taking the imprecise evaluations in the description of objects into account, intuition fuzzy information systems are introduced to handle with this problem. In this paper, attribute reductions are discussed in inconsistent ordered intuition fuzzy information decision tables. The conce...
متن کاملDominance-based rough set theory over interval-valued information systems
This paper proposes a new generalization of classical real-valued information systems, that is, interval-valued information systems. By defining an interval-valued dominance relation on a condition attribute, a rough set model and attribute reduction are established over interval-valued information systems. Moreover, several interesting properties are investigated by constructive approach. Furt...
متن کاملOn Dominance Relations in Disjunctive Set-Valued Ordered Information Systems
Set-valued information systems are generalized models of single-valued information systems. Its semantic interpretation can be classified into two categories: disjunctive and conjunctive. We focus on the former in this paper. By introducing four types of dominance relations to the disjunctive set-valued information systems, we establish a dominance-based rough sets approach, which is mainly bas...
