Communicating geographic information in context Extended abstract
نویسنده
چکیده
This paper examines extensions by Dretske, Barwise, Seligman and others to the Shannon-Weaver model of information communication, with special reference to geographic information. Classifications of entities into types are taken as the basis for information repositories, while structure-preserving mappins called infomorphism provide the linkages. A key notion is that of a channel, which can be used to model the notions of contextuality and spatial representations. Context is a key issue in communication, and the approach here is to allow the communication channel to mediate between the contexts of the communicators. In the case of geographic information, particular features of channel, such as accuracy and level of detail, will be examined, and the paper will discuss how vagueness and multi-cnextuality can be handled by the theory.

Extended Focus & Context for Visualizing Abstract Data on Maps
Traditionally, the subject of cartography has been geographic data, while information visualization has dealt with abstract, non-spatial information. With the ever increasing amount of data harvested worldwide, more and more of this data includes both geographic and abstract information at the same time. Efficient visualization of this data calls for the combination of maps with techniques for ...
متن کاملTemporal Spatial Inverse Semantics for Robots Communicating with Humans
Effective communication between humans often embeds both temporal and spatial context. While spatial context captures the geographic settings of objects in the environment, temporal context describes their changes over time. In this paper, we propose temporal spatial inverse semantics (TeSIS) to extend the inverse semantics approach to also consider the temporal context for robots communicating...

متن کاملContext-Sensitive Conversation Patterns for Agents in Wireless Environments
Abstract. We outline an approach for adapting software agent conversations between a mobile client and a service provider. The adaptation takes advantage of the context information characterizing the client’s current situation. The service provider takes this context information into account when selecting / creating a suitable interaction protocol for communicating with the client. Both the co...
