Abstract: In component composition-based system, the automatic composition oriented to high-level requirements is still confronted with many difficulties. Nevertheless, to support the automatic component composition based on semantic information to specific types of application in restricted context is still feasible. An approach that used keywords to describe semantic information, modeled the components and process of querying and applied a planner to search for the component sequence was proposed. The method has been used in a data query system for satellites testing and obtains favorable result.

Key words: component composition, keywords description, semantic information, satellites testing

摘要： 在基于组件的一般性应用系统中，面向自然语言描述需求的组件自动组合技术的研究仍然存在很多挑战。但是，在限定的上下文中，以基于语义的方式对特定应用提供组件自动组合的方法仍然是可行的。采用关键字描述语义信息，提出了一种基于语义的组件组合方法，对组件和请求过程建模，采用规划器搜索组件序列，完成组件的自动组合。方法已经应用于航天器自动化测试数据查询应用系统中，取得了较好的应用效果。
