We tackle the challenges involved in converting raw government data into high-quality Linked Government Data (LGD). Expand

We explore several approaches to the implementation of reconciliation services that allow third-party publishers to link their data to LOD hubs as part of the data publishing process. Expand

We propose an RDF Schema vocabulary as an interchange format among data catalogues and as a way of bringing them into the Web of Linked Data, where they can enjoy interoperability among themselves and with other deployed datasets. Expand

We present a "selfservice" approach to this problem: By connecting a powerful Gridworks-based data workbench application directly to data catalogs, via a standard Data Catalog Vocabulary, data professionals outside of government can contribute to the Linked Data conversion process, thus obtaining data for their own needs and benefiting the larger Linked Government Data effort.

We present the Semantic Public Service Portal (S-PSP), which structures and stores detailed public services semantically, so that they may be presented to citizens on-demand in a relevant, yet uncomplicated manner. Expand

SPARQL, the W3C standard querying language for RDF, provides rich capabilities for slicing and dicing RDF data. Expand

We study, and evaluate through simulation, the applicability of a few algorithms to scheduling queries received at a SPARQL endpoint. Expand

The semi-structured nature of Semantic Web data and its use of multiple vocabularies make it challenging to describe the structure of some RDF dataset. Expand

Graph aggregation is an important operation when studying graphs and has been applied in many fields. Expand
