Application of the formal concept analysis in evaluation of results of ANEWS questionnaire and physical activity of the Czech regional centers

Popis výsledku v původním jazyce

Formal concept analysis is a method of exploratory data analysis that aims at the extraction of natural clusters from object-attribute data tables. The clusters, called formal concepts, are naturally interpreted as human-perceived concepts in a traditional sense and can be partially ordered by a subconcept-superconcept hierarchy. The hierarchical structure of formal concepts (so-called concept lattice) represents structured information obtained automatically from the input data table. The goal of this paper is to describe a method of evaluation of ANEWS questionnaire by Formal concept analysis. We describe a method adjustment of questionnaire by scaling to classical formal context. After that we separate some attributes to groups and make so-called ?aggregate atributes?. This way we make modified formal context and calculate formal concept lattice. We define term ?characteristic function? for every concept. This is function, which for given extent or intent return a real number, which
