Data cube and cloud resources as platform for seamless geospatial computation

Giuliano Andrea Pagani, Luca Trani
2018 Proceedings of the 15th ACM International Conference on Computing Frontiers - CF '18  
"An OWL ontology may include descriptions of classes, properties and their instances.  ...  Given such an ontology, the OWL formal semantics specifies how to derive its logical consequences, i.e. facts not literally present in the ontology, but entailed by the semantics" [Smith et al., 2004  ...

Innovative Approaches for efficiently Warehousing Complex Data from the Web [article]

Fadila Bentayeb, Hadj Mahboubi, Cécile Favre, Omar Boussaïd
2017 arXiv   pre-print
Research in data warehousing and OLAP has produced important technologies for the design, management and use of information systems for decision support.  ...  Our contributions cover the main phases of the data warehouse design process: data integration and modeling and user driven-OLAP analysis.  ...  More specifically, the Resource Description Framework (RDF) may be used for describing Web data, and the Web Ontology Language (OWL) for creating an ontology that restricts the semantics of RDF descriptions  ...

Resource space model, OWL and database

Hai Zhuge, Yunpeng Xing, Peng Shi
2008 ACM Transactions on Internet Technology

Enriching integrated statistical open city data by combining equational knowledge and missing value imputation

Stefan Bischof, Andreas Harth, Benedikt Kämpgen, Axel Polleres, Patrik Schneider
2018 Journal of Web Semantics  
While most existing works about inference in Linked Data have focused on ontological reasoning in RDFS and OWL, we believe that these complementary methods and particularly their combination could be fruitfully  ...  In this paper we present the Open City Data Pipeline, a focused attempt to collect, integrate, and enrich statistical data collected at city level worldwide, and re-publish the resulting dataset in a re-usable  ...  Acknowledgements Part of the work was carried out with the support of the German Federal Ministry of Education and Research (BMBF) within the project "WIRE" (Grant 01|S16039B).  ...

Smart Environmental Data Infrastructures: Bridging the Gap between Earth Sciences and Citizens

José R.R. Viqueira, Sebastián Villarroya, David Mera, José A. Taboada
2020 Applied Sciences  
This paper reviews earth science data representation and access standards and technologies, and identifies the main challenges to overcome in order to enable their integration in semantic open data infrastructures  ...  Due to this, discovering, accessing and analyzing environmental datasets requires very specific skills, which is an important barrier for their reuse in many other application domains.  ...  Metadata related to semantic dataset schemes are naturally represented with OWL ontologies.  ...
