2 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Outline
! Semantic Web ontologies – widely applied ! Did Linked Data kill ontologies? ! Ontologies for Linked Data ! Linked Data for ontologies ! Research and discussion topics
3 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
! Develop and re-organize sites based on domain model ! E.g., sports ontology,
programme ontology
! One URI per thing ! Link content and allow
exploration of topics ! Leverage external resources
! E.g., MusicBrainz
Semantic Web Ontologies – widely applied: Content Navigation at BBC
12 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Linked Data for Ontologies ! When building and consuming ontologies use of Linked Data
sources would provide benefits
! Building: ! Inductive, incremental approach to ontology engineering
! Less manual modeling effort needed: use Linked Data as source ! No perfection needed: define mappings if you need them
! Collaborative approach to ontology engineering ! Exploiting Linked Data in games, tagging systems, wikis
! Consumption: ! The more reuse of Linked Data sources the easier the dynamic
extension of the ontology (e.g., instance of a class)
13 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Research and Discussion Topics
! New Challengies for ontology engineering methodologies
! Open Issues for Exploiting Linked Data & ontologies
14 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Do traditional methodologies for ontology engineering and evaluation need to be revised?
Enterprise Ontology [Uschold & King, 1995]
IDEF5 [Benjamin et al. 1994]
CO4 [Euzenat, 1995]
CommonKADS [Schreiber et al., 1999]
Holsapple&Joshi [Holsapple & Joshi, 2002]
On-To-Knowledge [Sure, 2002]
DILIGENT [Pinto et al., 2004]
NeOn Methodology [Gómez-Pérez, 2008]
Ontometric [Gómez-Pérez, 2004]
ONTOCOM [Simperl et al., 2006]
15 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
New Requirements for Methodologies
! More data-driven ! data first, ontology second
! More reuse-focused ! Leveraging ontology repositories, semantic search
engines ! Emphasis on alignment, especially at the instance level
! Application-oriented ! Human vs machine-oriented consumption (using
specific technologies)
16 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Open Issues for Exploiting Linked Data & ontologies
! What ontologies when to reuse for what kinds of data (statistical data, sensor information…) ! What guidelines are around ! Best practices for ontology reuse
! Statistics of ontology reuse in Linked Data
! Better usage of modularization concepts ! Application-driven reuse of parts of ontologies and Linked Data
17 July 6, 2011 2011 STI Semantic Summit – Linked Data & Ontologies
Open Issues for Exploiting Linked Data & ontologies
! What are the mechanisms for viral growth of Linked Data
! How to release open data’s potential as a major driver for innovation and for unlocking the full data value
! Exploiting the social Web ! What are business models for such initiatives
! Major driver for Open Linked Data: eGovernment ! Specification of standard ontologies in order to push the
release of public sector information as Linked Data
