Intelligent Resource Discovery using Ontology-Based Resource Profiles

J. Steven Hughes, Dan Crichton, Sean Kelly, Jerry Crichton, Thuy Tran, USA

Successful resource discovery across heterogeneous repositories is strongly dependent on the semantic and syntactic homogeneity of the associated resource descriptions. Ideally, resource descriptions are easily extracted from pre-existing standardized sources, expressed using standard syntactic and semantic structures, and managed and accessed within a distributed, flexible, and scaleable software framework. The Object Oriented Data Technology task has developed a standard resource description that can be used across domains to describe any resource. It uses a small set of generally accepted, broad scope descriptors while also providing a mechanism for the inclusion of domain specific descriptors. In addition this standard description can be used to capture hierarchical, relational, and recursive relationships between resources. In this paper we will present a intelligent resource discovery framework that consists of separate data and technology architectures, a standard resource description, and illustrate the concept using a case study.
