Abstract
Geo-tags are small pieces of information that are embedded in World Wide Web (WWW) content to describe the geographic context of the content. With the emergence of many Web 2.0 software tools, Web users are able to geo-tag online information such as webpages, digital images, audio and video files when they are browsing. As the volume of geo-tagged Web content grows, efficient retrieval, management and utilisation of these data become more and more important. This chapter addresses several key challenges in designing and implementing retrieval systems for geo-tagged Web content by developing an online map-based Geographic Information Retrieval (GIR) system called Geo Tag Mapper. The components of the proposed system are described in detail and the effectiveness and the usefulness of the system are demonstrated by applying it to a large collection of geo-tagged webpages and digital photos.
