Based on results from cognitive science, this paper examines the two fields of three-way
decision and granular computing, as well as their interplay. The ideas from one field shed …

Three-way granular computing is a paradigm of thinking and information processing in three
granules. We introduce a framework of three-way granular computing based on a hexagon …

Based on the notion of granular structures, a triarchic theory of granular computing
integrates three important perspectives, namely, philosophy of structured thinking …

Granular computing and knowledge reduction are two basic issues in knowledge
representation and data mining. Granular structure of concept lattices with application in …

Three-way concept lattices can supply much more information than classical concept lattices
since they contain the positive information and negative information between objects and …

Three-way concept analysis is a mathematical theory, which combines formal concept
analysis and three-way decision. The existing models, ie, three-way concept lattices and …

Attribute reduction is an important step in reducing computational complexity in order to
extract information from relational systems. Three of these systems are the formal, object …

Cognitive informatics and granular computing are two emerging fields of study concerning
information and knowledge processing. A central notion to this processing is information and …

This paper presents a generalisation of the classical property and object-oriented concept
lattices to a fuzzy environment based on the philosophy of the multi-adjoint paradigm. These …

This paper considers an epistemic interpretation of formal contexts, interpreting blank entries
in the context matrix as absence of information, which is in agreement with the usual focus …
