Methods of cognitive multicriteria classification, generalization of description and coordination of situations in hierarchical subject domains are developed. The methods consider prototypical effects and degrees of typicality of members according to semantic similarity measures of categories modeled in conceptual spaces. This approach also concretizes the notion of situation awareness for the proposed domain model, which allows to increase flexibility of classification and its robustness to data inaccuracy, as well as the speed of search for precedents.
