Verification of Distributed Dataspace Architectures
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
The space calculus is introduced as a language to model distributed dataspace systems, i.e. distributed applications that use a shared (but possibly distributed) dataspace to coordinate. ...
We give the syntax and operational semantics of this language and provide tool support for functional and performance analysis of its expressions. ...

In this paper, knowledge cubes are proposed as a semantically-guided data management architecture, where data management is influenced by the data semantics rather than by a predefined scheme. ...
Knowledge cubes are inspired by two prime architectures: (1) Dataspaces that provides an abstraction for data management where heterogeneous data sources can co-exist and it requires no prespecified unifying ...
It uses a rich data model, namely RDF [4] , to express the data through statements of equivalence, subclasses, and sub-property relations. ...

A primary challenge to large-scale data integration is creating semantic equivalences between elements from different data sources that correspond to the same real-world entity or concept. ...
At the core of this concept is a utility function that quantifies the desirability of a given state; thus, we devise a utility function for dataspaces based on query result quality. ...
