Fuzzy orderings in flexible query answering systems. (English) Zbl 1063.68047
Summary: This paper describes the benefits of using fuzzy orderings in flexible query answering systems. We provide a brief overview of those results from the theory of fuzzy orderings that are necessary to couple fuzzy orderings with flexible querying in a meaningful synergistic way. As one case study, we discuss a simple and pragmatic variant of a flexible query answering system – the so-called vague query system. The integration of fuzzy orderings into that system is provided in full detail along with examples.
