Multi-level semantic labelling of numerical values

Authors Sebastian Neumaier, Jürgen Umbrich, Josiane Xavier Parreira, and Axel Polleres

Abstract: With the success of Open Data a huge amount of tabular data sources became available that could potentially be mapped and linked into the Web of (Linked) Data. Most existing approaches to “semantically label” such tabular data rely on mappings of textual information to classes, properties, or instances in RDF knowledge bases in order to link – and eventually transform – tabular data into RDF.

Authors Sebastian Neumaier, Jürgen Umbrich, and Axel Polleres, Vienna University of Economics and Business, Vienna, Austria

Abstract: The Open Data movement has become a driver for publicly available data on the Web. More and more data – from governments, public institutions but also from the private sector – is made available online and is mainly published in so called Open Data portals. However, with the increasing number of published resources, there are a number of concerns with regards to the quality of the data sources and the corresponding metadata, which compromise the searchability, discoverability and usability of resources.
