Abstract

The Web (World Wide Web) generally reflects the relations between things. The current Web largely works on relatively static or stable relations for an information world. However, a massive kinds of dynamic and random relations populate the physical world, which expects an extension to the techniques of the current Web to facilitate applying the dynamic contexts of things. This research proposes a new Web type, the GeoChannel Web, for mapping and applying real-world dynamic and random relations to systematically support various context-based applications and services. A set of new concepts and technologies are proposed and designed for the GeoChannel Web. As new technical components, GeoPolicy Language can define context conditions; Geo-off-on communication model works for adaptively throttling communications based on dynamic contexts of things; AccessFeed can control dynamic correlation and interaction between things; Geoww-URI scheme as a novel URI model introduces context into traditional URIs for identifying GeoChannels, i.e. dynamically contextualized resources with condition-matched users. GeoChannel Discovery supports discovering GeoChannels from a virtual or physical world. GeoChannel Catalogue Services harvest and search real-time metadata that characterizes contexts of GeoChannels; while the physical-world approach supports acquiring Geoww-URIs of pervasive services from our physical environment. GeoChannel Web Engine is a service for mapping out context-based relations between things into a global-scale dynamic topology graph network named a GeoChannel Web. Technical mechanisms are explored for forming GeoChannel networks. Geonoon platform as a prototype implementation of these new techniques has been developed for supporting the use case projects that demonstrate creative and representative applications. The GeoChannel Web provides new techniques for contextualizing, identifying, discovering, clustering, and bridging things. All these new technical facilities constitute a Context-Organize layer that can fit into the general Web fabric, to provide new infrastructure for organizing real-world interaction and activities based on latest context. It can especially improve the current GeoWeb from a data-snapshot-browse-query platform into a live environment (e.g. a live Digital Earth) populated by crowdsourced dynamics, pervasive services and geo-clustered interaction.
