Introducing the aggregate "count" into flexible queries
Flexible querying aims at expressing preferences inside queries instead of strict requirements. We consider ordinary relational databases and flexible querying calling on fuzzy se...

Some meta-theorems on fuzzy cardinalities and their application
Several meta-theorems are proposed which state that certain inequalities satisfied by cardinalities of ordinary sets, are preserved under fuzzification.

Measuring Effectiveness in Fuzzy Information Retrieval
- We investigate extensions of the classical measurement of effectiveness in information retrieval systems, precision and recall, to situations where the answer is modeled by a fuz...

Fractional Collections with Cardinality Bounds, and Mixed Linear Arithmetic with Stars
Abstract. We present decision procedures for logical constraints involving collections such as sets, multisets, and fuzzy sets. Element membership in our collections is given by ch...

Extraction of fuzzy rules from support vector machines
The relationship between support vector machines (SVMs) and Takagi–Sugeno–Kang (TSK) fuzzy systems is shown. An exact representation of SVMs as TSK fuzzy systems is given for ...
