摘　　要：【目的/意义】在对本体构建的过程中,为了避免繁杂冗余信息,约简绝对不必要属性,保留核心属性与相对必要属性,以最核心的信息精确反映概念格及本体结构,提出了一种基于FCA与属性约简的本体合并方法。【方法/过程】首先对不同资源进行形式化处理,然后采用并叠置方法获得形式背景,并对形式背景进行属性约简与约简后的协调集判断,最终将约简集转换为相应的概念格,使用protege 3.4工具构建实验本体。【结果/结论】实验结果表明,对异构资源进行形式背景的属性约简有效地提高了本体构建效率,进一步丰富了概念间隐含的语义关系。【Purpose/significance】In the process of ontology construction, in order to avoid redundant information, reduce the absolute unnecessary attributes, preserve the core attributes and the relative essential attributes, with the most core information accurately reflects the concept lattice and ontology structure, a method that ontology merging method based on FCA and attribute reduction is proposed.【Method/process】Firstly, To formalize the different resources,and then to obtain the formal contexts by apposition-overlay operation, reduce the attributes of the formal context and judge reduction of coordinate set.Finally,it is necessary that the reduction set is transformed into the concept lattice,using protege 3.4 tool to construct an experimental ontology.【Results/conclusion】The experimental results show that the formal reduction of formal context for heterogeneous resources effectively enhances ontology construction efficiency, and further enriches the implicit semantic relations among concepts.
