Semantic Web enabled digital repositories

Dimitrios A. Koutsomitropoulos, Georgia D. Solomou, Andreas D. Alexopoulos, Theodore S. Papatheodorou
2009 International Journal on Digital Libraries  
Our methodology and results are applied on the University of Patras institutional repository.  ...  However, it is often the case that descriptive information about these assets, known as metadata, are usually semi-structured from a semantics point of view; implicit knowledge about this content may exist  ...  The entered expression is then parsed and evaluated to an OWL Description, namely, a (possibly anonymous) class, using the Manchester OWL Syntax Editor Parser, available from CO-ODE.  ...

Semantic query answering in digital repositories: Semantic Search v2 for DSpace

Dimitrios A. Koutsomitropoulos, Georgia D. Solomou, Theodore S. Papatheodorou
2013 International Journal of Metadata, Semantics and Ontologies  
A relevant such effort is the semantic search service for the popular DSpace digital repository system.  ...  Both an empirical and a quantitative evaluation suggest that the system can bring semantic search closer to inexperienced users and make its benefits evident in the context of digital repositories, such  ...  Precomputation is actually delegated to the reasoner, as a standard reasoning operation in Description Logics systems (Nardi and Brachman, 2002) .  ...

Ontological Semantics of Standards and PLM Repositories in the Product Development Phase [chapter]

M. Franke, P. Klein, L. Schröder, K.-D. Thoben
2011 Global Product Development  
In order to optimally exploit the large amounts of engineering information stored in contemporary PLM systems, the concept of knowledge based engineering (KBE) can be considered from a PLM perspective.  ...  By eventually combining product structures and implicit semantics provided by PLM-systems on the one hand, and domain-specific standards on the other hand we believe to have identified a key enabler KBE  ...  For using OWL-DL within Hets, it is necessary to generate the ontology in OWL Manchester Syntax [27] . Such a file can be opened with all common OWL readers, such as Protégé in version 4.  ...

The BioHub Knowledge Base: Ontology and Repository for Sustainable Biosourcing

Warren J. Read, George Demetriou, Goran Nenadic, Noel Ruddock, Robert Stevens, Jerry Winter
2016 Journal of Biomedical Semantics  
Method: The BioHubKB is the data repository of the IKMS; it employs Semantic Web technologies, especially OWL, to host data about chemical transformations, bio-renewable feedstocks, co-product streams  ...  The motivation for the BioHub project is to create an Integrated Knowledge Management System (IKMS) that will enable chemists to source ingredients from bio-renewables, rather than from non-sustainable  ...  The partners in these projects are: Unilever Research Port Sunlight, British Sugar Ltd, Croda, University of Liverpool, University of Manchester, University of Sheffield and Cybula Ltd.  ...

Aber-OWL: a framework for ontology-based data access in biology

Robert Hoehndorf, Luke Slater, Paul N Schofield, Georgios V Gkoutos
2015 BMC Bioinformatics  
Aber-OWL consists of an ontology repository, a set of web services and web interfaces that enable ontology-based semantic access to biological data and literature.  ...  We have developed the Aber-OWL infrastructure that provides reasoning services for bio-ontologies.  ...  For a user-specified query in Manchester OWL syntax, we construct a Lucene query string from the set of class descriptions returned from the Aber-OWL services.  ...

Applications of ontology design patterns in biomedical ontologies

Jonathan M Mortensen, Matthew Horridge, Mark A Musen, Natalya F Noy
2012 AMIA Annual Symposium Proceedings  
We found five patterns of the 69 patterns. Two of the eight ontologies contained these patterns.  ...  Ontology design patterns (ODPs) are a proposed solution to facilitate ontology development, and to help users avoid some of the most frequent modeling mistakes.  ...  Acknowledgements This work was supported by the NLM Grant 1R01GM086587-01. We are extremely grateful to Luigi Iannone for his support with OPPL.  ...
