Towards an Open Framework for Ontology Based Data Access with Protégé and DIG 1.1

Mariano Rodriguez, Diego Calvanese
2008 W3C Web Ontology Language (OWL) Experiences and Directions Workshop (OWLED)  
Ontology Based Data Access (OBDA) is concerned with the problem of mediating access to data sources through an ontology describing the information represented therein.  ...  This article presents the initial components of an Open Framework for OBDA that targets the previous issues; the first issue is addressed with an OBDA extension to the DIG 1.1 Interface; the second one  ...  We are also in the process of developing an OBDA-API for the OWL-API, in order to provide a solution to the issues that rise when using DIG 1.1 and large amounts of data.  ...

The OWL API: A Java API for OWL ontologies

Matthew Horridge, Sean Bechhofer
2011 Semantic Web Journal  
We present the OWL API, a high level Application Programming Interface (API) for working with OWL ontologies. The OWL API is closely aligned with the OWL 2 structural specification.  ...  It supports parsing and rendering in the syntaxes defined in the W3C specification (Functional Syntax, RDF/XML, OWL/XML and the Manchester OWL Syntax); manipulation of ontological structures; and the use  ...  The OWL API is used for loading and accessing ontologies and interfacing with the FaCT++ reasoner.  ...

Data management in Systems biology II - Outlook towards the semantic web [article]

Gerhard Mayer
2009 arXiv   pre-print
The problems existing today on the way to a true semantic web are pinpointed, different semantic web standards, tools and development frameworks are overlooked and an outlook towards artificial intelligence  ...  It is presented how ontologies can be used for the semantic enrichment of data and how this can contribute to the vision of the semantic web to become true.  ...  Acknowledgements This work was supported by the Federal Ministry of Education and Research (BMBF, Berlin, Germany, HepatoSys systems biology funding initiative, grant 0313080F).  ...

Exploring OWL and rules: a simple teaching case

Malgorzata Mochol, Anne Cregan, Denny Vrandecic, Sean Bechhofer
2008 International Journal of Teaching and Case Studies  
An automated reasoner is used for classification and the impact of the Open World Assumption on classification results is examined.  ...  This study includes developing a suitable ontology to represent a simple domain using an ontology editor, representing logical constraints using constructs available within OWL-DL, and then illustrating  ...  all the students, tutors and speakers who took part.  ...

Agent-Based Ontology Mapping Towards Ontology Interoperability [chapter]

Li Li, Yun Yang, Baolin Wu
2005 Lecture Notes in Computer Science  
Ontologies are widely used as data representations for knowledge bases and marking up data on the emerging Semantic Web.  ...  Hence, techniques for managing ontology come to the centre of any practical and general solution of knowledge-based systems.  ...  A component node contains an Ontology Server which provides for the interaction with the ontologies and the data sources.  ...

Turning the Mouse into a Semantic Device: The seMouse Experience [chapter]

Jon Iturrioz, Sergio F. Anzuola, Oscar Díaz
2006 Lecture Notes in Computer Science  
The mouse is configured with an ontology, and from then on, this ontology is used to annotate the distinct desktop resources.  ...  Traditional desktop operations are now re-interpreted and framed by this ontology: copy&paste becomes annotation&authoring, and folder digging becomes property traversal.  ...  This work is partially supported by the Spanish Science and Technology Ministry (MCYT) under contract TIC2002-01442.

Introduction to Linked Data and Its Lifecycle on the Web [chapter]

Axel-Cyrille Ngonga Ngomo, Sören Auer, Jens Lehmann, Amrapali Zaveri
2014 Lecture Notes in Computer Science  
With Linked Data, a very pragmatic approach towards achieving the vision of the Semantic Web has gained some traction in the last years.  ...  The term Linked Data refers to a set of best practices for publishing and interlinking structured data on the Web.  ...  In particular, we would like to thank Christian Bizer and Tom Heath, whose Chaper 2 of the book 'Linked Data -Evolving the Web into a Global Data Space' [53] served as a blueprint for Section 2; Sebastian  ...
