Abstract
An important facet of flexible querying and information retrieval is the ranking of the possible alternatives in the result. Adequate ranking information simplifies decision making and helps the user in finding faster the requested information. This paper deals with the construction of ranking methods, which are based on the use of extended possibilistic truth values. Extended possibilistic truth values are a flexible means to model query satisfaction, which additionally allow to deal with cases where some of the imposed query criteria are not applicable. Three alternative ranking approaches are presented and compared with each other based on their applicability in flexible database querying.
