Abstract:
In this paper we present some issues relating the semantic indexing of resources in distributed decentralized systems. We discuss some matter regarding the navigation between indexed resources and the way to enhance our model for answering more generic queries. The argument is introduced with a brief scenario focusing on e-learning domain, even if our goal is more general purpose. We discuss the role of ontologies in semantic indexing, moving from centralized systems to the distributed paradigm. We explain how to distribute a common index of resources semantically identified, composing a distributed knowledge base. The paper highlights the importance of an ontology system for the key generation and the use of specific domain ontologies.
