Modelling socio-political competition
Willem Conradie, Alessandra Palmigiano, Claudette Robinson +2
This paper continues the investigation of the logic of competing theories, be they scientific, social, political etc. We introduce a many-valued, multi-type modal language which we…
The logic of vague categories
Willem Conradie, Alessandra Palmigiano, Claudette Robinson +2
We introduce a complete many-valued semantics for basic normal lattice-based modal logic. This relational semantics is grounded on many-valued formal contexts from Formal Concept A…
Toward a Dempster-Shafer theory of concepts
Sabine Frittella, Krishna Manoorkar, Alessandra Palmigiano +2
In this paper, we generalize the basic notions and results of Dempster-Shafer theory from predicates to formal concepts. Results include the representation of conceptual belief fun…
Rough concepts
Willem Conradie, Sabine Frittella, Krishna Manoorkar +4
The present paper proposes a novel way to unify Rough Set Theory and Formal Concept Analysis. Our method stems from results and insights developed in the algebraic theory of modal…
Non normal logics: semantic analysis and proof theory
Jinsheng Chen, Giuseppe Greco, Alessandra Palmigiano +1
We introduce proper display calculi for basic monotonic modal logic,the conditional logic CK and a number of their axiomatic extensions. These calculi are sound, complete, conserva…
