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
Dr. Matthias Wauer | GeoLD 2015 ''Spatial Data Web Application in E-Commerce / Tourism'' 15. September 2015 UNISTER | Slide 7
Geospatial Data Sources
Example: LinkedGeoData theatres in Vienna, visualised using Facete

Motivation
Geospatial Motives: Generatedpolygons based on the densityof motive features
1. Extract pointsfrom sources
2. Apply Voronoitesselation
3. Intersect theVoronoi resultswith circles
4. Compute score:e.g., inverse ofpolygon surface
Example: Educational regionsin Germany
