Abstract: Aiming at some shortages like monotony of semantic description and lack of expansibility and adaptability, a semantic-component description model based on reflection is proposed. Based on the traditional component model, this model introduces ontology and reflection technology, makes the semantic description of component diverse and is able to dynamic update the component in accordance with system requirements and changed runtime environment. It supports automating combination and validation. It is used in mobile application, and the results show the improvement of self-adaptive for it.

摘要： 针对构件语义描述不丰富、构件的扩展性和适应性较差的问题，提出一种基于反射的语义构件模型。该模型在传统构件模型的基础上，引入本体及反射技术，使得构件语义描述丰富，并能根据系统要求及运行环境的变化，对构件进行动态修改。同时，该模型支持自动组装和推理。通过移动应用场景对该模型进行验证，结果表明，该模型的自适应性得到较高提升。
