Strategies for combining Twitter users geo-location methods

Twitter has become a major player in the social media scene with over half billion users and over 500 million tweets published daily. With this abundant data, researchers saw the opportunity to explore this data for monitoring events and tracking …


Personalized location recommendation by aggregating multiple recommenders in diversity

Location recommendation is an important feature of social network applications and location-based services. Most existing studies focus on developing one single method or model for all users. By analyzing data from two real location-based social …


Towards pervasive geospatial affect perception

Due to the enormous penetration of connected computing devices with diverse sensing and localization capabilities, a good fraction of an individual’s activities, locations, and social connections can be sensed and spatially pinpointed. We see …


Uncertain Voronoi cell computation based on space decomposition

To facilitate (k)-Nearest Neighbor queries, the concept of Voronoi decomposition is widely used. In this work, we propose solutions to extend the concept of Voronoi-cells to uncertain data. Due to data uncertainty, the location, the shape and the …

Über diese Zeitschrift

Located at the confluence of two rapidly advancing domains, GeoInformatica provides an effective forum for disseminating original and fundamental research and experience in the expanding uses of computer science for spatial studies.
Contemporary Earth studies require more and more sophisticated computing tools, and computer processing of Earth observations through Geographic Information Systems (GIS) currently attracts a great deal of attention from governmental, industrial and research worlds.
The journal covers spatial modeling and databases; human-computer interfaces for GIS; digital cartography; space imagery; parallelism, distribution and communication through GIS; spatio-temporal reasoning and more.

GeoInformatica presents the most innovative research results in the application of computer science applied to geographic information systems.
