background: family-centered care is an essential concept in cancer but there is no consensus about its meaning and it remains an abstract concept. this study was conducted with the purpose of analyzing the concept of family-centered care in cancer. methods: concept analysis of family-centered care was conducted using hybrid model that has 3 phases: theoretical, field work and final analytical p...

background: over the years, the concept technology has modified, especially from the viewpoint of the development of scientific knowledge as well as the philosophical and artistic aspects. however, the concept of technology in nursing are still poorly understood. only small qualitative studies, especially in iran, have investigated this phenomenon and they just are about information technology....

This is the first part of a large survey paper in which we analyze recent literature on Formal Concept Analysis (FCA) and some closely related disciplines using FCA. We collected 1072 papers published between 2003-2011 mentioning terms related to Formal Concept Analysis in the title, abstract and keywords. We developed a knowledge browsing environment to support our literature analysis process....

We show a relationship between two theoretical approaches of Formal Concept Analysis working with so-called heterogeneous formal context i.e. such context in which each object and attribute can have own data-type. One of them is presented in [19]; each value in a formal context is some Galois connection between the lattices corresponding to the appropriate object and attribute. Another approach...

We provide a general framework for pattern structures by investigating adjunctions between posets and their morphisms. Our special interest is the impact of pattern morphisms on the induced concept lattices. In particular we are interested in conditions which are sufficient for the induced residuated maps to be injective, surjective or bijective. One application is that every representation con...

Feature component maps describe which components are needed to implement a particular feature and are used early in processes to develop a product line based on existing assets. This paper describes a new technique to derive the feature component map and additional dependencies utilizing dynamic information and concept analysis. The method is simple to apply, cost-effective, largely language in...

A new general and efficient architecture for working with pattern structures, an extension of FCA for dealing with “complex” descriptions, is introduced and implemented in a subsystem of Formal Concept Analysis Research Toolbox (FCART). The architecture is universal in terms of possible dataset structures and formats, techniques of pattern structure manipulation.

A reasonable size example coming from cognitive psychology is re-analyzed with standard tools of FCA and Lattice Analysis. Developmental shifts / classifications are explored on a descriptive and graphical viewpoint, through attribute implications and unglued decomposition in regular intervals. This assesses child similarities in performance and behavior, while comparing intervals focuses on wh...

Adjoint pairs or adjoint triples defined on lattices have proven to be a useful tool when working in fuzzy formal concept analysis. This paper shows that adjoint pairs and triples can play as well an important role within the framework of multilattices, especially in order to form the Galois connections needed to build concept multilattices.

The most popular basis in Formal Concept Analysis is the Duquenne-Guigues basis, which ensure minimality in the number of dependencies and it is built with pseudo-intents, and some method to calculate these basis from an arbitrary set of implications have been introduced. We propose in this paper, an automated method to calculate a left-minimal direct basis from the set of all implications buil...
