Four-Fold Formal Concept Analysis Based on Complete Idempotent Semifields

open access: yesMathematics, 2021
Formal Concept Analysis (FCA) is a well-known supervised boolean data-mining technique rooted in Lattice and Order Theory, that has several extensions to, e.g., fuzzy and idempotent semirings.

Towards a generalisation of formal concept analysis for data mining purposes [PDF]

open access: yes, 2006
In this paper we justify the need for a generalisation of Formal Concept Analysis for the purpose of data mining and begin the synthesis of such theory.

Formal Concept Analysis

open access: yesElectronic Notes in Discrete Mathematics, 1999
Formal concept analysis (FCA) [71] is a mathematical theory for concepts and concept hierarchies that reflects an understanding of “concept” which is first mentioned explicitly in the Logic of Port Royal [2] in 1668 and has been established in the German standard ‘DIN 2330 – Concepts and terms; general principles’ [19].

Inference of mixed information in Formal Concept Analysis [PDF]

open access: yes, 2017
Negative information can be considered twofold: by means of a negation operator or by capturing the absence of information. In this second approach, a new framework have to be developed: from the syntax to the semantics, including the management of ...

FUZZY FORMAL CONCEPT ANALYSIS UNTUK KEMIRIPAN DOKUMEN

open access: yesSimetris: Jurnal Teknik Mesin, Elektro dan Ilmu Komputer, 2013
ABSTRAK Fuzzy logic dapat dimasukkan ke dalam ontologi untuk representasi ketidakpastian informasi yang ditemukan di banyak aplikasi domain karena kurangnya jelas batas-batas antara konsep domain. Fuzzy ontologi dihasilkan dari konsep hirarki yang telah

Continuous Domains in Formal Concept Analysis [PDF]

open access: yesFundamenta Informaticae, 2021
Formal Concept Analysis (FCA) has been proven to be an effective method of restructuring complete lattices and various algebraic domains. In this paper, the notion of contractive mappings over formal contexts is proposed, which can be viewed as a generalization of interior operators on sets into the framework of FCA.

Galois Connections between Semimodules and Applications in Data Mining [PDF]

open access: yes, 2007
In [1] a generalisation of Formal Concept Analysis was introduced with data mining applications in mind, K-Formal Concept Analysis, where incidences take values in certain kinds of semirings, instead of the standard Boolean carrier set.
