Towards a Rule-Based Approach for Context-Aware Applications

摘要

Context-aware applications can sense and explore the users' context in order to provide proper and useful services to these users. These applications can react intelligently upon changes in the user's context, performing actions relevant to the user, the application itself, and the interaction between user and application. Context-aware reactive behaviors can be expressed by using rules written in a Domain-specific Language, coined ECA-DL, specially developed for context-aware applications. This paper proposes support for the development of a generic component capable of executing rules written using ECA-DL. This component executes these rules by using Jess, which is a well-known tool for developing rule-based systems.
