Semantic understanding of geotagged pictures
Proceedings of the international conference on Multimedia information retrieval, 2010Semantic understanding based only on vision cues has been a challenging problem. This problem is particularly acute when the application domain is unconstrained photos available on the Internet or in personal repositories. In recent years, it has been shown that metadata captured with pictures can provide valuable contextual cues that complement the ...

Finding similar destinations with flickr geotags
Proceedings of the 27th Annual ACM Symposium on Applied Computing, 2012The amount of geo-referenced information on the Web is increasing thanks to the large availability of location-aware mobile devices and map interfaces. In particular, in photo collections like Flickr the coexistence of geographic meta-data and text-based annotations (tags) can be exploited to infer new, useful information. This paper introduces a novel

Geo-clustering of Images with Missing GeoTags
2010 IEEE International Conference on Granular Computing, 2010Images with GPS coordinates are a rich source of information about a geographic location. Innovative user services and applications are being built using geotagged images taken from community contributed repositories like Flickr. Only a small subset of the images in these repositories is geotagged, limiting their exploration and effective utilization ...

Spatially Aware Term Selection for Geotagging
IEEE Transactions on Knowledge and Data Engineering, 2014The task of assigning geographic coordinates to textual resources plays an increasingly central role in geographic information retrieval. The ability to select those terms from a given collection that are most indicative of geographic location is of key importance in successfully addressing this task.

Proceedings of the 6th Workshop on Geographic Information Retrieval, 2010
Geotagging is the process of recognizing textual references to geographic locations, known as toponyms, and resolving these references by assigning each lat/long values. Typical geotagging algorithms use a variety of heuristic evidence to select the correct interpretation for each toponym.

Tag-geotag correlation in social networks
Proceedings of the 2008 ACM workshop on Search in social media, 2008This paper presents an analysis of the correlation of annotated information unit (textual) tags and geographical identification metadata geotags. Despite the increased usage of geotagging in collaborative tagging systems, most current research focuses on textual tagging alone in solving the tag search problem.

A study on the accuracy of Flickr's geotag data
Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval, 2013Obtaining geographically tagged multimedia items from social Web platforms such as Flickr is beneficial for a variety of applications including the automatic creation of travelogues and personalized travel recommendations. In order to take advantage of the large number of photos and videos that do not contain (GPS-based) latitude/longitude coordinates,

Geotagging Aided by Topic Detection with Wikipedia
2011It is known that geography-aware keyword queries correspond to a significant share of the users’ demand on search engines. This paper describes a strategy for tagging documents with place names according to the geographical context of their textual content by using a topic indexing technique that considers Wikipedia articles as a controlled vocabulary.
