A Mapping from Conceptual Graphs to Formal Concept Analysis [chapter]

2011 Lecture Notes in Computer Science  
in FCA.  ...  represented by triples of the form source-concept, relation, target-concept, can be transformed into a set of binary relations of the form (target-concept, source-concept relation) creating a formal context  ...  CGs and FCA can thus interoperate in a practical way, combining their power in an integrated and intuitive conceptual structure.  ...

Foliated semantic networks: Concepts, facts, qualities

Robert Marty
1992 Computers and Mathematics with Applications  
AnMogously to Wille's lattice-concepts theory connecting objects and attributes, we define "represcntatlon-contexts" connecting two corresponding classes of phenomena formalized in terms of Category Theory  ...  Wille's basic lattice-concepts theory of objects and their attributes.  ...  The lattice of the diffe~nt possible specie~ of "representation-context" depending on the fundamentM categories (1, 2 or 3) of the entities on either side of our (Galois) "representation-relatiorm."  ...

Exploring, Reasoning with and Validating Directed Graphs by Applying Formal Concept Analysis to Conceptual Graphs [chapter]

Simon Andrews, Simon Polovina
2018 Lecture Notes in Computer Science  
Extensive comparative studies in this arena already exist, pre-CGFCA [10] .  ...  A thread of further work is therefore required to discover the comparative benefits of each approach, perhaps leading to how they may best work together in validating directed graphs through FCA.  ...  In simple terms, Simon's trip to London depends on travelling there by coach and booking into the OpenSky hotel.  ...

An item selection procedure to maximise scale reliability and validity

J. Raubenheimer
2004 SA Journal of Industrial Psychology  
In terms of his strategy, the latter aspects of validity are maximised by means of exploratory factor analyses.  ...  The benefits that accrue by using this incremental approach are demonstrated in terms of Allport and Ross' (1967) Religious Orientation Scale, a widely-used psychological instrument.  ...  The internal validity of the conclusions reached in such research directly depends on the reliability (e.g., internal consistency) and the validity of the questionnaires or scales used.  ...

On Different Types of Heterogeneous Formal Contexts

Ubomir Antoni, Stanislav Kraj i, Ondrej Kridlo
2013 Proceedings of the 8th conference of the European Society for Fuzzy Logic and Technology  
We provide a generalization of Formal Concept Analysis that works with different types of the values in a heterogeneous formal context.  ...  An appropriate counterpart of the basic theorem on concept lattices is formulated. We suggest the transformation of the heterogeneous formal context to Galois connectional approach.  ...  Classical formal context described in Ganter & Wille's book [15] utilizes binary relation between a set of objects and a set of attributes.  ...

speaking to us, should be finally laid to rest by the papers collected in this volume.  ...  In this afterword, I propose that these papers, investigating data journeys in fields from particle physics to urban planning, show that even the primary, original, state of data is not free from researchers  ...  What counts as base level will depend on the context and what counts as a higher-level set of correlations in one context may be base level in another.  ...

Local Malcev conditions

Alden F. Pixley
1972 Canadian mathematical bulletin  
The author is indebted to the referee for several useful suggestions on the organization of the paper.  ...  It is to be emphasized that the integer k of Theorem 3.1 in general depends on the congruence cf> of Lemma 3.2 and hence on the subset F of 31.  ...  Either by this method or direct examination of their proofs one sees that their Malcev conditions become "local Malcev conditions" in the more general context of local varieties.  ...
