GeoMM 2014: the third ACM multimedia workshop ongeotagging and its applications in multimedia.

It is our great pleasure to welcome you to the Third ACM Workshop on Geotagging and Its Applications in Multimedia -- GeoMM'14. This year's event continues the workshops in 2012 and 2013, with the goal of building a forum for the presentation and synthesis of vision and insight from leading experts and practitioners on the developing directions of geotagging research related to multimedia. Following the success in previous years, the GeoMM workshop serves as a venue for the premier research in geotagging and multimedia, and continues to attract submissions from a diverse set of researchers, who address newly arising problems within this emerging field. Five regular papers are presented in this workshop, covering a number of novel applications and new methodologies. An invited paper is also presented to introduce the related MediaEval 2014 Placing task, which consists of 5 million geotagged photos and 25,000 geotagged videos. We believe this workshop will benefit more and more research works in the broad research field.
