SWS: Semantic Web Server

This is the semantic web server of the Logic and Intelligent Data research group at the Department of Informatics, University of Oslo. This server contains software and other webpages related to our research, projects and teaching, in various levels of maturity.

The contents are divided into the following somewhat overlapping categories:

OptiqueVQS: Project homepage of OptiqteVQS: a visual query formulation tool for expressing information needs in terms of queries over ontologies.
Linked Open NPD FactPages v2: Project homepage for a Linked Open Data version of the Norwegian Petroleum Directorate's FactPages, updated to the new version of the FactPages.
Boundz: A vocabulary for expressing reservations about incoming data
Det Sentrale Folkeregisteret: Project homepage for master thesis work with Det Sentrale Folkeregisteret (Norwegian National Register) as case.
Linked Open NPD FactPages: Project homepage for a Linked Open Data version of the Norwegian Petroleum Directorate's FactPages. Now superseeded by an updated version, see over.
Gul liste: Project homepage for a LOD version of the Cultural Heritage Management Office in Oslo's Yellow List of culturally valuable buildings.

Sgvizler: Sgvizler is a javascript which renders the result of SPARQL SELECT queries into charts or html elements.
Mapper Dan: Web-app validating RDF transformations for conservativity.
Synapse: Web-app converting Excel spreadsheets to RDF according to transformation templates. In Norwegian.
Oris: Web-app illustrating uses of public sector data in RDF format. In Norwegian.
Mr. Oblig: Web-app testing deliveries of mandatory exercises in our course on Semantic Technologies, INF3580.
AddressServlet: Small web-servlet which collects data about business units from The Brønnøysund Register Centre's webservices and using content negotiation presents it as either RDF/XML or HTML.

RDF datasets published according to Linked Open Data principles.

Linked Open NPD FactPages v2: Linked Open Data version of the Norwegian Petroleum Directorate's FactPages version 2.
Linked Open NPD FactPages: Linked Open Data version of the Norwegian Petroleum Directorate's FactPages. Outdated, superseeded by a new version.
Gul liste: LOD version of the Cultural Heritage Management Office in Oslo's Yellow List of culturally valuable buildings.

Ontology Alignment Evaluation Initiative (OAEI) tracks organised by members of the LogID group.

Disease and Phenotype track: This track is based on a real use case where it is required to find alignments between disease and phenotype ontologies.
Large BioMed track: This track consists of finding alignments between the Foundational Model of Anatomy (FMA), SNOMED CT, and the National Cancer Institute Thesaurus (NCI). These ontologies are semantically rich and contain tens of thousands of classes.
Interactive track: This track offers the possibility to compare different interactive matching tools which require user interaction. The goal is to show if user interaction can improve the matching results, which methods are most promising and how many interactions are necessary.

Boundz: A vocabulary for expressing reservations about incoming data
NPD v2: An ontology currently under delopment in the Linked Open NPD FactPages v2 project.
NPD: A thin vocabulary used in the Linked Open NPD FactPages project.
World: OWL ontology used by the world dataset running in a D2R server instance.

Installations of SW software serving our datasets, or used for testing and/or educational purposes.

Linked Data API: Running on Elda.
SPARQLer: The standard interface to our RDF Joseki database instance, with a SPARQL query interface and query validator.
Snorql: Access our datasets using Snorql.
Sgvizler: Access our datasets using Sgvizler.
D2RQ: A D2R Server running with a RDFized version of the MySQL world database.
