Knowledge on a Budget
Ondrej Majer, Krishna Manoorkar, Wolfgang Poiger +1
In various computational systems, accessing information incurs time, memory or energy costs. However, standard epistemic logics usually model the acquisition of evidence as a cost-…
Questions as cognitive filters
Willem Conradie, Krishna Manoorkar, Alessandra Palmigiano +2
In this paper, we develop a logico-algebraic framework for modeling decision-making through deliberation in multi-agent settings. The central concept in this framework is that of i…
Fuzzy Lattice-based Description Logic
Yiwen Ding, Krishna Manoorkar
Recently, description logic LE-ALC was introduced for reasoning in the semantic environment of enriched formal contexts, and a polynomial-time tableaux algorithm was developed to c…
Normative implications
Andrea De Domenico, Ali Farjami, Krishna Manoorkar +4
We continue to develop a research line initiated in \cite{wollic22}, studying I/O logic from an algebraic approach based on subordination algebras. We introduce the classes of slan…
Correspondence and Inverse Correspondence for Input/Output Logic and Region-Based Theories of Space
Andrea De Domenico, Ali Farjami, Krishna Manoorkar +3
We further develop the algebraic approach to input/output logic initiated in \cite{wollic22}, where subordination algebras and a family of their generalizations were proposed as a…
Defeasible Reasoning on Concepts
Yiwen Ding, Krishna Manoorkar, Ni Wayan Switrayni +1
In this paper, we take first steps toward developing defeasible reasoning on concepts in KLM framework. We define generalizations of cumulative reasoning system C and cumulative re…
Query Answering in Lattice-based Description Logic
Krishna Manoorkar, Ruoding Wang
Recently, the description logic LE-ALC was introduced for reasoning in the semantic environment of the enriched formal contexts, and a tableaux algorithm was developed for checking…
Flexible categorization using formal concept analysis and Dempster-Shafer theory
Marcel Boersma, Krishna Manoorkar, Alessandra Palmigiano +3
The framework developed in the present paper provides a formal ground to generate and study explainable categorizations of sets of entities, based on the epistemic attitudes of ind…
Toward the van Benthem Characterization Theorem for Non-Distributive Modal Logic
Yiwen Ding, Krishna Manoorkar, Mattia Panettiere +1
In this paper, we introduce the simulations and bisimulations on polarity-based semantics for non-distributive modal logic, which are natural generalizations of those notions on Kr…
Modal reduction principles: a parametric shift to graphs
Willem Conradie, Krishna Manoorkar, Alessandra Palmigiano +1
Graph-based frames have been introduced as a logical framework which internalizes an inherent boundary to knowability. They also support the interpretation of lattice-based (modal)…
Obligations and permissions, algebraically
Andrea De Domenico, Ali Farjami, Krishna Manoorkar +3
We further develop the algebraic approach to input/output logic initiated in \cite{wollic22}, where subordination algebras and a family of their generalizations were proposed as a…
Obligations and permissions on selfextensional logics
Andrea De Domenico, Ali Farjami, Krishna Manoorkar +3
We further develop the abstract algebraic logic approach to input/output logic initiated in \cite{wollic22}, where the family of selfextensional logics was proposed as a general ba…
Labelled calculi for the logics of rough concepts
Ineke van der Berg, Andrea De Domenico, Giuseppe Greco +3
We introduce sound and complete labelled sequent calculi for the basic normal non-distributive modal logic L and some of its axiomatic extensions, where the labels are atomic formu…
Labelled calculi for lattice-based modal logics
Ineke van der Berg, Andrea De Domenico, Giuseppe Greco +3
We introduce labelled sequent calculi for the basic normal non-distributive modal logic L and 31 of its axiomatic extensions, where the labels are atomic formulas of a first order…
Outlier detection using flexible categorisation and interrogative agendas
Marcel Boersma, Krishna Manoorkar, Alessandra Palmigiano +3
Categorization is one of the basic tasks in machine learning and data analysis. Building on formal concept analysis (FCA), the starting point of the present work is that different…
Game semantics for lattice-based modal μ-calculus
Yiwen Ding, Krishna Manoorkar, Mattia Panettiere +2
In this paper, we generalize modal -calculus to the non-distributive (lattice-based) modal -calculus and formalize some scenarios regarding categorization using it. We also p…
Causal Kripke Models
Yiwen Ding, Krishna Manoorkar, Apostolos Tzimoulis +2
This work extends Halpern and Pearl's causal models for actual causality to a possible world semantics environment. Using this framework we introduce a logic of actual causality wi…
Non-distributive description logic
Ineke van der Berg, Andrea De Domenico, Giuseppe Greco +3
We define LE-ALC, a generalization of the description logic ALC based on the propositional logic of general (i.e. not necessarily distributive) lattices, and semantically interpret…
A Meta-Learning Algorithm for Interrogative Agendas
Erman Acar, Andrea De Domenico, Krishna Manoorkar +1
Explainability is a key challenge and a major research theme in AI research for developing intelligent systems that are capable of working with humans more effectively. An obvious…
Flexible categorization for auditing using formal concept analysis and Dempster-Shafer theory
Marcel Boersma, Krishna Manoorkar, Alessandra Palmigiano +3
Categorization of business processes is an important part of auditing. Large amounts of transnational data in auditing can be represented as transactions between financial accounts…
Subordination Algebras as Semantic Environment of Input/Output Logic
Andrea De Domenico, Ali Farjami, Krishna Manoorkar +3
We establish a novel connection between two research areas in non-classical logics which have been developed independently of each other so far: on the one hand, input/output logic…
Modal reduction principles across relational semantics
Willem Conradie, Andrea De Domenico, Krishna Manoorkar +4
The present paper establishes systematic connections among the first-order correspondents of Sahlqvist modal reduction principles in various relational semantic settings which incl…
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…
