Overview
This is a small info page about the Semantic Search facility for DSpace developed at HPCLab, University of Patras.unmigrated-wiki-markup
*Semantic Search* allows intelligent search of DSpace content, using Semantic Web technologies. Most inportantly semantic search *does not affect the original DSpace data model* but, by using a technique known as semantic profiling \ [1] it allows inference-based search and knowledge discovery that would otherwise be impossible.
To promote semantic interoperability, semantic search is performed against an ontology that is automatically populated with harvested metadata through the OAI-PMH interface. The repository's ontology follows the OWL 2.0 proposed standard and implements its new extensions. It can be accessed independently here. The semantic search facility offers sound and complete reasoning for such ontologies based on the FaCT++ Description Logics Reasoner. Development utilizes the OWL API, thus it is straightforward to use other compatible reasoners as well, such as Pellet. Query syntax follows the Manchester Syntax familiar in the DL-query Tab of Protege 4.0.
