2004 Lecture Notes in Computer Science  
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.  ...  A distributed dataspace architecture 2 The Space Calculus Fig. 3 . 3 Auxiliary operators on multisets.  ...

We investigate the formulation of a formal semantics for the industrial software architecture Splice.  ...  In this report, we present a set of basic Splice interaction primitives that is both powerful and easy to implement. We define a semantics for this language based on a conceptual global dataspace.  ...  Acknow ledgements We would like to thank Marcello Bonsangue, Michel Chaudron, Paul Dechering, Rix Groenboom, Michel Reniers and the anonymous referees of SAC2000 5 for their useful comments on a draft  ...

A first tutorial on dataspaces

Michael Franklin, Alon Halevy, David Maier
2008 Proceedings of the VLDB Endowment  
Uncertainty in data integration Modeling and reasoning about uncertainty in data, queries and semantic mappings are critical for management of dataspaces.  ...  An iTrail is essentially a statement of semantic equivalence of two access paths through the data, and their addition allows queries to obtain more complete answers from a dataspace.  ...

An Effective User Behavior Modeling Approach for Data Services in the Field of Materials Engineering

Xin Cheng, Changjun Hu, Yang Li, Wei Lin
2013 Journal of Computers  
For dealing with the problem of distributed heterogeneous data sharing and satisfying the demands of data service, the complex association and dynamic changes should be tracked timely.  ...  In this paper, we propose an effective user behavior modeling approach based on the Open Cloud Service Architecture (OCSA) to manage the domain scientific data.  ...  Elsayed et al proposed a dataspace management system architecture [19] which combined the dataspace concept with the grid technology.  ...

Knowledge cubes — A proposal for scalable and semantically-guided management of Big Data

Amgad Madkour, Walid G. Aref, Saleh Basalamah
2013 2013 IEEE International Conference on Big Data  
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.  ...

Pay-as-you-go user feedback for dataspace systems

Shawn R. Jeffery, Michael J. Franklin, Alon Y. Halevy
2008 Proceedings of the 2008 ACM SIGMOD international conference on Management of data - SIGMOD '08  
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.  ...  ACKNOWLEDGEMENTS The authors would like thank Jayant Madhavan, Omar Benjelloun, the Google Base team, and the members of the Berkeley database research group for many discussions regarding this work.  ...
