Abstract

The paper contains the propositions of employing type-2 fuzzy sets in linguistic summaries of databases. This new approach is the promising extension for ordinary linguistic summaries [1][4][14] and for recently introduced interval-valued linguistic summaries [11]. The two original concepts of a type-2 summarizer and a type-2 linguistic quantifier are proposed as the extensions for ordinary and interval-valued corresponding constructs. This innovation is supposed to provide better handling of natural language uncertainties that are impossible to be modelled with ordinary fuzzy sets. An application on sample data is presented.
