MarcoPolo: a community system for sharing and integrating travel information on maps

ABSTRACT

The tagging technique has been widely applied in existing Web 2.0 systems, where users label resources with tags for effective classification and efficient retrieval of resources. Location-aware geographical tags (geo-tags) are required if users want to mark location-sensitive resources to digital maps. Large volumes of different kinds of user-created tags pose challenges to the effective organization of community resources using tags. Issues such as guaranteeing the quality of tags and supporting various tag-based queries emerge. In this demo, we present MarcoPolo, a Web 2.0 community system that allows users to define the hierarchical textual geo-tags and mark resources to a map using geo-tags. Statistical and feedback mechanisms are applied to guarantee the quality of tags (including geo-tags). The MarcoPolo system provides two effective interfaces for users to browse and search resources: one is the keyword-based interface and the other is the map-based interface.
