Incorporating “Semantic Discovery ” into a Ubiquitous Computing Infrastructure

Abstract

Abstract. The fundamental standards and protocols of a Ubiquitous Computing System must define common interfaces and message formats. In addition to the common interfaces and message formats, the entities of the system must know or discover the “semantics ” of the messages: the vocabulary of the messages, which includes the names and valid values of message elements. In this paper, we show how we have successfully used technologies from the Semantic Web to solve important aspects of this challenge. We have implemented “semantic queries”, as part of a semantic discovery process for a Ubiquitous Computing Environment. We argue that semantic discovery should be an integral part of the fundamental protocols for Ubiquitous Computing Systems.
