SAMEW allows for dealing within a common frameworkwith several aspects relevant to similarity query processing as well as with the inherent imprecision that characterizes data, user requests and query results. Non-Boolean, namely fuzzy and similarity, predicates are used to rank tuples according to specific criteria. Complex multi-predicate queries can be formed by means of logical connectives, whose semantics is parameterized in order to ...

Nowadays, the vast volume of collected digital data obliges us to employ processing methods like pattern recognition and data mining in order to reduce the complexity of data management. The output of these techniques are knowledge artifacts, heterogeneous in both structure and semantics. We claim that the concept of pattern is a good candidate for generic representation of these novel information types. The PANDA project is aimed at studying the main issues related to pattern handling. In this paper we ...
