Asymmetric Composition of Possibilistic Operators in Formal Concept Analysis: Application to the Extraction of Attribute Implications from Incomplete Contexts
Sign Up to like & getrecommendations! Published in 2017 at "International Journal of Intelligent Systems"
DOI: 10.1002/int.21900
Abstract: Formal concept analysis theory (FCA) classically relies on the use of the Galois powerset operator. Formal similarities between possibility theory and formal concept analysis have led to the use of possibilistic operators in FCA, which… read more here.
