The generalization of Boolean information retrieval systems is still of interest to scholars. In spite of the fact that commercial systems use Boolean retrieval mechanisms, such systems still have some limitations. One of the main problems is that such systems lack the ability to deal well with impr

β¦ Synopsis
This paper describes a technique by which a fuzzy subset can be linguistically labelled. The technique involves the separation of a given fuzzy set into a certain number of specific subsets. The labelling is based on assignment of labels to these specific subsets and their concatenation with connectives "AND" and "OR".
The technique allows the user to specify, up to a certain number, his own primary subsets and their respective names. The input subset is also freely specified and properties like normality of input subsets do not constitute any constraint.

In this paper, a rather expressive fuzzy temporal logic for linear time is introduced. First, this logic is a multivalued generalization (Lukasiewicz style) of a two-valued linear-time temporal logic based on, e.g., the "until" operator. Second, it is obtained by introducing a generalized time quant
This paper considers user interface design world (UIDW) as a system of communication lines. It necessitates the adoption of a UI design method, centered on language application. For that reason, this approach to UI design is called linguistic approach. The basic characteristics of communication requ
