Quality Aspects in Translation of Relative Locations into Absolute Locations
Regensburg, Germany on September 10th, 2019.

The workshop is organized in collaboration with ISPRS, WGIV/3 . The aim of the workshop is to bring together researchers from domains such as GIS, Computer Science, Linguistic to discuss new ideas and issues related to quality and relative location.


The transformation of a relative location (when people describe location by using landmarks and spatial relations) to an absolute location (represented by geographic coordinates) is a standard task in many scientific domains, such as:

  • Linguistics and computer science: detection of named spatial entity coming from text and disambiguation of the named spatial entity to assess it a location by using different gazetteers.
  • Computer science and GIS: make reference to the concept of Naïve Geography  defined by Egenhofer and Mark (1995) and consists in defining methods to identify an area (represented by geographic coordinates) for a given location (e.g., “I'm in front of the lake”) expressed by a triplet (subject, spatial relation, landmarks).
  • Linguistics, cognitive science and psychology: a relative location is subjective, depends on users, on the context and both landmarks and spatial relations can be subject of interpretation and uncertainty.

Approaches for the transformation typically use data like gazetteers and rely both on authoritative and volunteered geographic information (VGI). It is essential for users to understand that the quality of these tools and sources determined the quality of the result. This requires communication and utilization of quality information for both input data and results. There is need to better assess the quality of gazetteers (e.g., completeness, thematic and geographic accuracy, etc.) and VGI sources as well as to evaluate the quality of results. There is need to deal with conflicts between different sources of information (e.g., the same entity of the real world is part of three sources of information; which one should be used?). There is need for formalisms for dealing with heterogeneous data for decision-making, etc.

The workshop will provide a platform to present practical experiences, new ideas and discuss state of the art and novel approaches to deal with these issues.

Participants are expected to submit an extended abstract not exceeding 4 pages for revision and selection of presenters.
