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

Jaume Baixeries, Victor Codocedo, Mehdi Kaytoue, Amedeo Napoli
2018 Discrete Applied Mathematics  
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  ...  We show that these dependencies can be formalized in the framework of Formal Concept Analysis (FCA) using a previous formalization introduced for standard FDs.  ...  In Section 5 we propose a generic characterization and computation of approximate-matching dependencies in terms of Pattern Structures.  ...

A Proposition for Combining Pattern Structures and Relational Concept Analysis [chapter]

Víctor Codocedo, Amedeo Napoli
2014 Lecture Notes in Computer Science  
In a nutshell, this adaptation allows the scenario where RCA needs to be applied in a relational context family composed by pattern structures instead of formal contexts.  ...  In this paper we propose an adaptation of the RCA process enabling the relational scaling of pattern structures.  ...  Introduction Relational Concept Analysis (RCA) [10] is an extension of Formal Concept Analysis (FCA) [4] based on a scaling process.  ...

Towards a Generic Framework for Trustworthy Program Refactoring

Dániel Horpácsi, Judit Kőszegi, Dávid J. Németh
2021 Acta Cybernetica  
Apparently, it is always challenging to relate executable refactoring implementations with the formal semantics of the transformed language.  ...  Refactoring has to preserve the dynamics of the transformed program with respect to a particular definition of semantics and behavioral equivalence.  ...  In the former case, more high-level concepts can be added to the dependency analysis; in the latter, more refactorings can be considered during the generalization.  ...

Semantic Sparse Representation of Disease Patterns

Artur Przelaskowski
2010 International Journal of Electronics and Telecommunications  
Semantic Sparse Representation of Disease Patterns Sparse data representation is discussed in a context of useful fundamentals led to semantic content description and extraction of information.  ...  Proposed methodology of sparse disease patterns considers accuracy of sparse representation to estimate target content for detailed analysis.  ...  Moreover, it does not require a close match between the sampling pattern and characteristic image structures giving sparse structure essence estimates.  ...

LESTER: using paradigm cases in a Quasi-Precedential legal domain

K. A. Lambert, M. H. Grunewald
1989 Proceedings of the second international conference on Artificial intelligence and law - ICAIL '89  
Formally, the process is viewed as a purely internal dispute resolution mechanism unique to the parties who structured iu A proper conception of the arbitrator's function is basic.  ...  Typically, in domains in which there are a limited number of formal decisions and in which there is a well-defined hierarchy of decisionmakers, the concept of precedent-bound decisionmaking exists in a  ...

Classification Based Retrieval Using Formal Concept Analysis [chapter]

Belén Díaz-Agudo, Pedro A. González-Calero
2001 Lecture Notes in Computer Science  
This paper shows how the use of Formal Concept Analysis (FCA) can support CBR application designers, in the task of discovering knowledge embedded in a case base.  ...  FCA application provides an internal sight of the case base conceptual structure and allows finding regularity patterns among the cases.  ...  Structured domains are characterized by the fact that there is an intrinsic dependency between certain elements in the domain.  ...

1988 Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '88  
This is done by taking advantage of implicit higher-order structure in the association of terms with text objects.  ...  Most approaches to retrieving textual materials depend on a lexical match between words in users' requests and those in or assigned to database objects.  ...  DEFICIENCIES OF KEYWORD RETRIEVAL METHODS A standard approach to finding relevant textual material depends on matching individual words in users' requests with individual words in database texts.  ...

2000 Lecture Notes in Computer Science  
Knowledge discovery from unlabeled data comprises two main tasks: identification of "natural groups" and analysis of these groups in order to interpret their meaning.  ...  The architecture can be extended to other supervised/unsupervised learning algorithms that comply with the same desiderata.  ...  It can be observed that the number of clusters depends on the threshold and the distance metric used to compare the inputs with the clusters.  ...

Automatic extraction of framework-specific models from framework-based application code

Michal Antkiewicz, Thiago Tonelli Bartolomei, Krzysztof Czarnecki
2007 Proceedings of the twenty-second IEEE/ACM international conference on Automated software engineering - ASE '07  
Framework-specific models represent the design of application code from the framework viewpoint by showing how framework-provided concepts are implemented in the code.  ...  In this paper, we describe an experimental study of the static analyses necessary to automatically retrieve such models from application code.  ...  Concept instances are characterized by configurations of features and the features correspond to structural and behavioral patterns in the completion code.  ...
