【摘要】 [目的/意义]异构资源蕴含着优势互补的综合情境信息,可以在基于概念格整合的集成情境协同知识构建(CKAIC)中为用户决策制定构建出感知应用的情境本体。[方法/过程]这种情境本体构建方法需要依次对异构资源形式背景进行并叠置运算和冗余信息剔除的属性约简、协调集判断及其概念格构造。[结果/结论]通过情境适配性应用分析可知,经过属性集协调的异构资源概念格能够将其所包含的综合情境精练地转化成用户感知应用的适用性情境本体,为用户决策提供参考的解决方案。更多还原

【Abstract】 [Purpose/Significance] Heterogeneous resources contains comprehensive context information with complementary advantages,which can be constructed a context ontology to user perceive for decision making in collaborate knowledge architecture integrating context( CKAIC) based on the integration of concept lattice. [Method/Process] This context ontology construction method required the judgment of attribute reduction coordination set of eliminating redundant information and its construction of concept lattice integrating context by successively superimposing operation on heterogeneous resource formal background. [Result/Conclusion] Through the application analysis of context adaptation,it can be seen that the heterogeneous resource concept lattice which was coordinated by the attribute set could transform the comprehensive context it contains into the adaptive context ontology of user-aware applications pithily,and provide a reference solution for user decision making.更多还原
