Motivation

What we need:
Dr. Matthias Wauer | GeoLD 2015 ''Spatial Data Web Application in E-Commerce /Tourism'' 15. September 2015 UNISTER | Slide 6
Motivation
Winter vacation in the mountains with culture Search
1. Preprocess search motives
2. Interpret search query
3. Perform search and return matching offers

Example: Culture motive
●
nearby theatres, operas, art
expos
●
music festivals
●
museums
Sources in LOD we used:
●
DBpedia
●
LinkedGeoData

Motivation

Geospatial Motives: Generated
polygons based on the density
of motive features
1. Extract points
from sources
2. ApplyVoronoi
tesselation
3. Intersect the
Voronoi results
with circles
4. Compute score:
e.g., inverse of
polygon surface
Example: Educational regions
in Germany
