      A control theoretical approach to self-optimizing block transfer in Web service grids 

      Gounaris, A.; Yfoulis, C.; Sakellariou, R.; Dikaiakos, Marios D. (2008)
      Nowadays, Web Services (WS) play an important role in the dissemination and distributed processing of large amounts of data that become available on the Web. In many cases, it is essential to retrieve and process such data ...

      A core grid ontology for the semantic grid 

      Wei, X.; Dikaiakos, Marios D.; Sakellariou, R. (2006)
      In this paper, we propose a Core Grid Ontology (CGO) that define s fundamental Grid-specific concepts, and the relationships between them. One of the key goals is to make this Core Grid Ontology general enough and easily ...

      Towards a grid information knowledge base 

      Xing, Wei; Dikaiakos, Marios D.; Sakellariou, R. (2007)
      In this paper, we present our work on building a Grid information knowledge base, which is a key component of a semantic Grid information system. A Core Grid Ontology (CGO) is developed for building a Grid knowledge base
