We take great pleasure in welcoming you all to the sixth Workshop on Geographic Information Retrieval (GIR'10). The GIR workshops have been running since 2004 and have been, up to now, hosted by SIGIR and CIKM. This year marks a departure as we strike out on our own, running a two day workshop with more time for interaction, and more space and freedom to design our programme. The support we have received from ACM SIGSPATIAL has gone a long way to making this possible, and through our in cooperation status it has been possible to once again ensure that all papers are archived in the ACM Digital Library, continuing the development of a valuable resource for all of those involved in research in this area. We are delighted to see a vibrant mix of regulars and newcomers at this year's workshop having received submissions from an increasing breadth of groups and locations, demonstrating that interest in GIR continues to grow. Furthermore, we are very pleased to have two discussion sessions, one on credibility in GIR and the other on commercial needs related to research. Dirk Ahlers (University of Oldenburg), Vanessa Murdock (Yahoo!) and Radu Jurca (Google) are thanked for their willingness and energy in organising these discussions, which we hope will prove fruitful for all participants. The call for papers resulted in a good variety of short and long papers relating to differing aspects of GIR ranging from geocoding and geographic scopes, through methods for ranking to the application of GIR in advertising. An interesting development is the increase in the number of papers exploring different types of collections, often of archived materials, with the associated challenges brought by working with such resources and the importance of dealing with changing references to space over time. All papers were reviewed by three members of the programme committee. The 13 long and 11 short papers that were selected for presentation from 34 papers submissions provide valuable contributions to the state of the art in GIR and cast new light on some of the major challenges. We hope that the workshop will succeed not only in its aim of reporting on where we are now, but also on how the academic and commercial research community can set a distinctive, relevant and above all exciting research agenda for the coming years.
