Welcome

Geospatial Data and the Semantic Web

Geospatial data or geographic information is the data that identifies a geographic location of natural or constructed features and boundaries on the Earth (e.g. oceans, buildings, countries, rivers, etc). Geographical knowledge bases are among the largest in existence and have high importance in a variety of everyday applications. The data can be mapped and often manipulated with Geographic Information Systems (GIS), however the integration of external data sets into these systems is time-consuming and complex. GeoKnow will provide the necessary tools and methods to easily integrate and process data across a wide range of data sources on the web of data.

Possibly one of the most interesting and promising outcomes of the activity surrounding the Web 2.0 evolution has been the large-scale adoption of Linked Data. Among the largest data sets are those with explicit geographic references, e.g. LinkedGeoData (2 billion triples), DBpedia (1 billion triples) and GeoNames (146 million triples). Other data sets carry implicit geographic references such as PubMed (797 million triples) or Freebase (1 billion triples). A problem GeoKnow aims to solve is the lack of rich geospatial links between the data.

GeoKnow in a nutshell

What

  • Bring geospatial knowledge integration to the Linked Data Web
  • Billion-triple geospatial reasoning and data provenance
  • Qualitative interlinking and fusing of geospatial and semantic information
  • Adaptive geospatial exploration, authoring and curation

Why

  • Unlock isolated islands of geographic information
  • 80% of all data has some spatial dimension, most of it is not processable today
  • Geographic data authoring with millions of users requires powerful tools

For whom

  • Added value for the companies and the Linked Data Web community
  • Cost-effective data integration for SMEs
  • Enterprises can add value to their data with volunteered geographic information
  • Users from travel industry will benefit from more background information

Ontos starts project at SECO using GeoKnow Generator ( 2014-10-27T16:36:34+01:00 Daniel Hladky)

2014-10-27T16:36:34+01:00 Daniel Hladky

Ontos was selected as an implementation partner at SECO to implement a linked data stack platform. Based on the GeoKnow Generator Ontos will develop a data management and search platform that will allow the management of linked open government data. The GeoKnow generator will used as the backend system that orchestrates the various tools. Read more about "Ontos starts project at SECO using GeoKnow Generator"

The Linked Data Stack ( 2014-09-17T16:37:09+02:00 Alejandra Garcia Rojas)

2014-09-17T16:37:09+02:00 Alejandra Garcia Rojas

The Linked Data Stack aims to simplify the deployment and distribution of tools that support the Linked Data life cycle. Moreover, it eases the information flow between components to enhance the end-user experience while harmonising the look and feel. It comprises a number of tools for managing the life-cycle of Linked Data. Read more about "The Linked Data Stack"
