“…In what follows Att is a function that returns the attributes of its argument, Ext is function that returns the extension of its argument, D are a set of derived (user defined) properties, that do not exist in the local classes but can be derived based on existing attributes, Gc are global classes, Lc are their corresponding local classes. 2 A detailed description of the generated interschema correspondence establishment rules following the execution of the integration operators is given in Tawil et al (2008).…”

“…For instance, the Name property maybe spelt Name in one class and Pat-Name in another. These conflicts are identified and delt with during the conflict detection and resolution phase (see Tawil et al 2008) of the global schema generation process. Establishing interschema correspondence relationships and defining proper transformation to reconcile any heterogeneity is only possible when the semantic description of each property is explicitly defined to our system and the correspondence establishment rules to resolve conflicts are specified.…”

“…The decision of which operator to apply to a given set of integration units depends on the interschema semantic relationships among these units (e.g. equivalence, overlap, .. etc), and user preferences, see (Li et al 2010;Tawil et al 2008;Li and Ling 2004). Semantic preservation rules for validating user decisions have been defined.…”

“…In Tawil et al (2002Tawil et al ( , 2008 we argue that a better, more flexible approach to support heterogeneous ISs interoperability would result from creating user defined mediator views above the distributed databases of the ISs -with each mediator view tailored towards a certain group of specific users' requirements or application programs functionalities. These user-defined mediators are created by applying a set of semantically-rich integration operators, capable of reconciling the semantic and structural differences that are likely to arise when integrating distributed, heterogeneous and autonomous servers.…”

Research and development activities relating to the grid have generally focused on applications where data is stored in files. However, many scientific and commercial applications are highly dependent on Information Servers (ISs) for storage and organization of their data. A datainformation system that supports operations on multiple informa-tion servers in a grid environment is referred to as an interoperable grid system. Different perceptions by end-users of interoperable systems in a grid environment may lead to dif-ferent reasons for integrating data. Even the same user might want to integrate the same distributed data in various ways to suit different needs, roles or tasks. Therefore multiple mediator views are needed to support this diversity. This paper describes our approach to supporting semantic interoperability in a heterogeneous multi-information server grid envi-ronment. It is based on using Integration Operators for generating multiple semantically rich RDF/OWL-based user defined mediator views above the grid participating ISs. These views support different perceptions of the distributed and heterogeneous data available. A set of grid services are developed for the implementation of the mediator views.

The application of semantic grid in education has provided huge opportunities for academic institutions especially universities to aggregate disparate information technology components to create a unified single system ( [11], [9].…”

Abstract-There is an increasing reliance on the web for many software application deployments. Millions of services ranging from commerce, education, tourism and entertainment are now available on the web, making the web to be the largest database in the world as of today. However, the information available on the web is syntactically structured whereas the trend is to provide semantic linkage to them. The semantic web serves as a medium to enhance the current web in which computers can process information, interpret, and connect it to enhance knowledge retrieval. The semantic web has encouraged the creation of ontologies in a great variety of domains. In this paper, the conceptual framework for an ontology-based examination system and the ontology required for such examination systems were described. The domain ontology was constructed based on the Methontology method proposed by Fernández (1997). The ontology can be used to design and create metadata elements required developing web-based examination applications and can be interoperate-able with other applications. Taxonomic evaluation and the Guarino-Welty Ontoclean techniques were used to assess and refined the domain ontology in other to ensure it is error-free.
