Abstract
This paper is concerned with the design and implementation of the context handlers for context-awareness in a ubiquitous computing environment. The context handlers address design issues of context handling: abstraction of context values, semantic interoperability of context information, logical and semantic interpretation of context information, and structuralization of context information for specifying various situations. To address these design issues, we define a structural context model, a context schema based on ontology, and user-friendly context value ontology. We also use ontology reasoning and rule-based reasoning. This paper focuses on context handling methods in a context-aware system. We expect that these context handling methods will help context-aware system developers to design and implement context handlers in a ubiquitous computing environment.
