Weakening of Fuzzy Relational Queries: an Absolute Proximity Relation-Based Approach
نویسندگان
چکیده
In a previous work, we have explored a proximity-based approach for relaxing queries involving fuzzy predicates. This proximity was defined in a relative way. In this paper we consider an absolute proximity and we show how it can be used for the purpose of query weakening. The main features of the weakening mechanism resulting from the use of this kind of proximity are investigated as well. Lastly, a comparative study of some methods proposed to deal with the issue of fuzzy query weakening is provided.

Apply Uncertainty in Document-Oriented Database (MongoDB) Using F-XML
As moving to big data world where data is increasing in unstructured way with high velocity, there is a need of data-store to store this bundle amount of data. Traditionally, relational databases are used which are now not compatible to handle this large amount of data, so it is needed to move on to non-relational data-stores. In the current study, we have proposed an extension of the Mongo...

متن کاملDiscovery of Abstract Knowledge from Non-Atomic Attribute Values in Fuzzy Relational Databases
In this paper we introduce attribute-oriented induction with partial vote propagation – a new approach allowing acquisition of generalized knowledge from uncertain data. We utilize a proximity-based fuzzy relational database as the medium carrying the original information, where the lack of precise information about an entity is reflected via insertion of multiple attribute values, and the fuzz...

The pioneer work of image compression/reconstruction based onfuzzy relational equations (ICF) and the related works are introduced. TheICF regards an original image as a fuzzy relation by embedding the brightnesslevel into [0,1]. The compression/reconstruction of ICF correspond to thecomposition/solving inverse problem formulated on fuzzy relational equations.Optimizations of ICF can be consequ...
متن کاملAttribute-oriented fuzzy generalization in proximity- and similarity-based relational database systems
In this article we investigate an attribute-oriented induction approach for acquisition of abstract knowledge from data stored in a fuzzy database environment. We utilize a proximity-based fuzzy database schema as the medium carrying the original information, where lack of precise information about an entity can be reflected via multiple attribute values, and the classical equivalence relation ...
