A Context-Aware Software Adaptation Framework

点击翻译按钮获取中文摘要

There is an increasing demand for software systems that dynamically adapt their behavior at runtime in response to changes. Research into these systems has been conducted by researchers from two communities with two different emphases: self-adaptivity and context-awareness. On one hand, research in context-awareness is more concerned with how to model, process, and manage the context information but limited on how a system adapts itself in response to unanticipated changes in the context information. On the other hand, research in self-adaptivity is more about how to adapt the system's structure and/or behavior in response to requirements and/or context changes (possibly unanticipated changes), with less attention to how context is modeled, processed, and managed. In practice, the line between the two is rather blurred, and the engineering of a context-aware adaptive system needs to consider both aspects in a systematic manner.
