- 2. Table of content • Introduction • Collecting ontologies • Describing ontologies • Evaluating ontologies • Catalogue generation • Web application • Conclusions and future work Building an Ontology Catalogue for Smart Cities – María Poveda Villalón 2
- 3. Introduction • Facilitate ontology reuse • There are many ontologies (and other resources) useful to describe energy and cross-domain data • One place to discover ontologies • It is not trivial to find them • Specific for energy efficiency and smart cities • Search engines and ontology registries are too general or off-topic (biology, environment, etc.) • Ontology assessment • The quality of ontologies in the Web is unknown Building an Ontology Catalogue for Smart Cities – María Poveda Villalón 3
- 4. Goals 4 • Minimal effort from the community using a web form • (Semi)Automatic process for generating a catalogue • To collect scModels: • Ontologies: rdf-s, OWL, skos • Other type of models: pdf, xml, uml, etc. • Semi-automatic quality assessment • Curated metadata • Ontology evaluation Building an Ontology Catalogue for Smart Cities – María Poveda Villalón

The process: Minimal effort from the community http://goo.gl/SG0pMA Detailed information Contributors Submit ontology metadata Suggest ontology URI http://goo.gl/z4TlFO Ontology catalogue http://smartcity.linkeddata.es/ Ontology Metadata Curate metadata Metadata Curators RDF representation HTML representation • Review Literature • Analyze Standardization and Institutional Bodies • Lookup Ontology Catalogues • Dataset Investigation • Contact Stakeholders form Populators Minimal information form Building an Ontology Catalogue for Smart Cities – María Poveda Villalón 6
- 7. To collect scOntologies: web-based form Identifier Definition Name The name given to the ontology Description A free-text account of the ontology Domains The different domains covered by the ontology Version The version of the ontology Creation date The date of formal issuance of the ontology Last update Most recent date on which the ontology was changed, updated or modified Contact person The person(s) primarily responsible for making the ontology Publisher The organization that published the ontology License The license of the ontology URI The URI of the ontology Namespace The preferred namespace URI to use when using terms from this vocabulary Format The format of the ontology Ontology language The language in which the ontology is implemented Language The language of the ontology Comments Further information about the ontology in the context of our catalogue References Resources that might provide additional information (documents, papers, etc.) http://goo.gl/SG0pMA Introduce yours!

- 19. Future work • To include more ontologies • and more focused in smart cities and energy fields • To include search features • so that user can look for specific classes or properties • To include filter features • so that user can narrow down the list of ontologies according to their requirements • Something else?

Notas do Editor
- Unos 15 minutos Good afternoon ladies and gentelmen. Thank you for attending this session. Today I’m going to present an online catalogue for gathering energy efficiency and related domains ontologies.
- De aqui ir al catalogo on line y explicarlo
- ----- Notas de la reunión (5/20/14 15:58) ----- there will no be a compelte estandard. Smart cities is not the same as for sensors, there will be not a smart city board. You stay in the liquid situation of the ontology.
