Paraconsistent Logic Programs with Four-Valued Rough Sets [chapter]

Jan Małuszyński, Andrzej Szałas, Aida Vitória
2008 Lecture Notes in Computer Science  
This paper presents a language for defining four-valued rough sets and to reason about them. Our framework brings together two major fields: rough sets and paraconsistent logic programming.  ...  On the one hand it provides a paraconsistent approach, based on four-valued rough sets, for integrating knowledge from different sources and reasoning in the presence of inconsistencies.  ...  Our framework relates and brings together two major fields: rough sets [8] and paraconsistent logic programming [3] .  ...

A Framework for Reasoning with Rough Sets [chapter]

Aida Vitória
2005 Lecture Notes in Computer Science  
Rough sets framework has two appealing aspects. First, it is a mathematical approach to deal with vague concepts.  ...  This thesis 1 proposes a language that caters for implicit definitions of rough sets obtained by combining different regions of other rough sets.  ...  The This Reduct of a logic program and reduct of a decision table (commonly used in the rough set framework) are two independent notions.  ...

Defining Rough Sets by Extended Logic Programs [article]

Jan Małuszyński, Aida Vitória (Linköping University, Sweden)
2002 arXiv   pre-print
We show how definite extended logic programs can be used for defining and reasoning with rough sets. Moreover, a rough-set-specific query language is presented and an answering algorithm is outlined.  ...  Thus, we not only show a possible application of a paraconsistent logic to the field of rough sets as we also establish a link between rough set theory and logic programming, making possible transfer of  ...  This gives a basis for efficient implementation of rough sets in logic programming. Since mid-eighties rough sets have been a subject of intensive research.  ...
