Jaume Baixeries, Mehdi Kaytoue, Amedeo Napoli
2014 Annals of Mathematics and Artificial Intelligence  
Whereas it has been deeply investigated in those fields, strong links exist with the mathematical framework of Formal Concept Analysis.  ...  We also show how another class of dependencies can be characterized with that framework, namely, degenerated multivalued dependencies.  ...  Acknowledgements This research work has been partially supported by the Spanish Ministry of Education and Science (project TIN2008-06582-C03-01), EU PASCAL2 Network of Excellence, and by the Generalitat  ...

Characterizing approximate-matching dependencies in formal concept analysis with pattern structures

Jaume Baixeries, Victor Codocedo, Mehdi Kaytoue, Amedeo Napoli
2018 Discrete Applied Mathematics  
We show that these dependencies can be formalized in the framework of Formal Concept Analysis (FCA) using a previous formalization introduced for standard FDs.  ...  Our new results state that, starting from the conceptual structure of a pattern structure, and generalizing the notion of relation between tuples, approximate-matching dependencies can be characterized  ...  This research work has been supported by the SGR2014-890 (MACDA) project of the Generalitat de Catalunya, and MINECO project APCOM (TIN2014-57226-P) and partially funded by the French National Project  ...

Conceptual analysis of lexical taxonomies

Aldo Gangemi, Nicola Guarino, Alessandro Oltramari
2001 Proceedings of the international conference on Formal Ontology in Information Systems - FOIS '01  
Some principles from a forthcoming OntoClean methodology are applied to the ontological analysis of WordNet.  ...  We shall integrate these tools with techniques derived from ONIONS project, whose original task was the development of a large-scale, axiomatized ontology library for medical terminology.  ...  Acknowledgements We would like to thank Claudio Masolo, Chris Partridge, Domenico Pisanelli, and Geri Steve for the fruitful discussions and comments on the earlier version of this paper.  ...

Towards a compiler analysis for parallel algorithmic skeletons

Tobias J. K. Edler von Koch, Stanislav Manilov, Christos Vasiladiotis, Murray Cole, Björn Franke
2018 Proceedings of the 27th International Conference on Compiler Construction - CC 2018  
In this paper we argue that commutativity is a more suitable concept supporting formal characterization of parallel algorithmic skeletons.  ...  We show that existing commutativity definitions cannot be easily adapted for practical use, and develop a new concept of commutativity based on liveness, which readily integrates with existing compiler  ...  Skeleton Characterization In the following paragraphs we are going to formally characterize a selection of widely used skeletons using the commutativity concept introduced in Definition 1.  ...

The unique quality of Faulkner’s typical syntax, as with other major features of his art, originates in his concept of reality and his penchant for minute analysis, with the multiplicity of a given moment  ...  Physically they are often characterized by unusual length, by patterns of involuted dependent elements, clause modified by clause, by phrase, with dependencies as far removed, sometimes, as three and four  ... 

Fuzzy Concept Lattices Constrained by Hedges

Radim Belohlavek, Vilem Vychodil
2007 Journal of Advanced Computational Intelligence and Intelligent Informatics  
As a consequence, we obtain a theorem characterizing the structure of concept lattices with hedges which generalizes the well-known main theorem of ordinary concept lattices.  ...  We introduce new, parameterized, concept-forming operators and study their properties. We obtain an axiomatic characterization of the concept-forming operators.  ...  Formal concept analysis deals with input data in the form of a table with rows corresponding to objects and columns corresponding to attributes which describes a relationship between the objects and attributes  ...

Emergence in effective field theories

Jonathan Bain
2013 European Journal for Philosophy of Science  
This essay considers the extent to which a concept of emergence can be associated with Effective Field Theories (EFTs).  ...  I suggest that such a concept can be characterized by microphysicalism and novelty underwritten by the elimination of degrees of freedom from a high-energy theory, and argue that this makes emergence in  ...  Their scaling behavior can be determined by dimensional analysis with respect to L 0 .  ...

Concept-oriented model: inference in hierarchical multidimensional space [article]

Alexandr Savinov
2014 arXiv   pre-print
These models are mainly aimed at numeric (quantitative) analysis where the notions of inference and semantics are not well defined.  ...  We propose a novel approach to inference in multidimensional space based on the concept-oriented model of data and introduce elementary operations which are then used to define constraint propagation and  ...  This approach is based on using formal concept analysis (FCA) for finding a lattice of formal concepts.  ...
