Optimal Granularity Selection and Attribute Reduction in Meso-granularity Space [PDF]
The conventional formal concept analysis adopts a meso-granularity formal context to meet the requirements of cross-layer granulation of data.However,it does not effectively combine the search for optimal granularity with attribute reduction,nor does it ...

Consistent Sets of Soft Contexts Defined by Soft Sets
We introduce the notion of consistent sets of soft contexts and investigate its characterizations. For the purpose of studying the characterizations of consistent sets, we introduce the notions of 1 0 and 2 0 classes of independent ...

Fuzzy Implication and Functional Dependency on Formal Context
Fuzzy formal concept analysis(FFCA) is a development of formal concept analysis(FCA) with the degree of relation between objects and attributes. Using FCA approach, we will investigate the condition logical implication for fuzzy functional dependency. We

Family as a context for development of formal operations [PDF]
This paper is focused on the family as a context for development of formal thinking. Parents’ mediation and cultural tools in family environment were investigated through relationship between formal thinking and the two basic dimensions of family ...

Context-aware approach for formal verification
The Context-aware approach has proven to be an effective technique for software model-checking verification. It focuses on the explicit modelling of environment as one or more contexts.

Knowledge cores in large formal contexts
AbstractKnowledge computation tasks, such as computing a base of valid implications, are often infeasible for large data sets. This is in particular true when deriving canonical bases in formal concept analysis (FCA). Therefore, it is necessary to find techniques that on the one hand reduce the data set size, but on the other hand preserve enough ...

Relevant Attributes in Formal Contexts [PDF]
Computing conceptual structures, like formal concept lattices, is in the age of massive data sets a challenging task. There are various approaches to deal with this, e.g., random sampling, parallelization, or attribute extraction. A so far not investigated method in the realm of formal concept analysis is attribute selection, as done in machine ...
