Phenomenological Percolation in Conceptual Networks associated to Complex Systems
(IEEE Computer Society, 2014)
A notion of phenomenological percolation for Conceptual Structures associated to Complex Systems (CS) is proposed. This process on concept lattices (from Formal Concept Analysis) consists in the allocation of (non-previous) ...

On the Phenomenological Reconstruction of Complex Systems—The Scale-Free Conceptualization Hypothesis
(Wiley, 2013)
Phenomenological reconstruction of a complex system (CS) from collected and selected data allows us to work with formal models (representations) of the system. The task of building a qualitative model necessitates the ...

Confidence-Based Reasoning with Local Temporal Formal Contexts
(Springer, 2011)
Formal Concept Analysis (FCA) is a theory whose goal is to discover and to extract Knowledge from qualitative data. It provides tools for reasoning with implication basis (and association rules). In this paper we analyse ...

Conservative Retractions of Propositional Logic Theories by Means of Boolean Derivatives: Theoretical Foundations
(Springer, 2009)
We present a specialised (polynomial-based) rule for the propositional logic called the Independence Rule, which is useful to compute the conservative retractions of propositional logic theories. In this paper we show ...

Foundational Challenges in Automated Data and Ontology Cleaning in the Semantic Web
(IEEE Computer Society, 2006)
The application of automated reasoning systems to data cleaning in the Semantic Web raises many challenges on the foundational basis of cleaning agent design. The authors discuss some of them. They finally argue that ...

Generalizing Programs via Subsumption
(Springer, 2003)
In this paper we present a class of operators for Machine Learning based on Logic Programming which represents a characterization of the subsumption relation in the following sense: The clause C 1 subsumes the clause C 2 ...

Qualitative Reasoning on Complex Systems from Observations
(Springer, 2013)
A hybrid approach to phenomenological reconstruction of Complex Systems (CS), using Formal Concept Analysis (FCA) as main tool for conceptual data mining, is proposed. To illustrate the method, a classic CS is ...

Pedestrian Behavior Mining from Data
(University of York, UK, 2015)
A general -observation-based- qualitative framework to extract agent-based pedestrian behavior is presented. To extract qualitative rules from data we use tools, from Formal Concept Analysis, for implicational reasoning.

On the Complexity of Shared Conceptualizations
(Springer, 2012)
In the Social Web, folksonomies and other similar knowledge organization techniques may suffer limitations due to both different users’ tagging behaviours and semantic heterogeneity. In order to estimate how a social ...
