SWS: Semantic Web Server

Contents

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:

Projects

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.

Software

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.

Datasets

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 Outdated, superseeded by a new version.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

OAEI Evaluation

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.

Vocabularies

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.
