摘　　要：多领域知识图谱关联融合是实现知识共享、支撑跨领域知识综合分析和方案决策的重要基础。基于水利多业务领域本体在术语、结构、概念上的异构特点,提出一种基于多策略的跨领域知识图谱关联融合方法,包括:结合多维相似度计算方法与领域规则,进行等价和同形异义关系判定;利用领域规则,进行上下义和部分关系判定;根据判定结果,合并等价节点,保留同形异义节点,新增上下义和部分关联。以防洪与供水2个业务领域的知识图谱为例,进行跨领域知识图谱关联融合方法的应用。应用情况表明:该方法能较好满足水利专业跨领域知识关联融合的要求,可实现跨领域知识图谱的自动关联匹配,融合后的图谱可为更大范围的知识关联应用提供支撑。The integration of multi domain knowledge graphs is an important foundation for achieving knowledge sharing,supporting cross do⁃main knowledge comprehensive analysis,and scheme decision⁃making.Based on the heterogeneous characteristics of terminology,structure,and concepts in the multibusiness domains of water conservancy,this paper proposed a cross domain knowledge graph association fusion method based on multiple strategies,including:determining equivalence and homonymy relationships by combining multidimensional similarity calculation methods and domain rules;using domain rules to determine synonyms and partial relationships;based on the judgment results,merging equivalent nodes,retaining homomorphic but dissimilar nodes,adding synonyms and partial associations.The application of the multi⁃strategy association and fusion method was illustrated by using knowledge graphs from the flood control and water supply domains.The application results indicate that this method effectively meets the requirements for cross⁃domain knowledge association and fusion in the water conservancy field,enabling automatic cross-domain knowledge graph matching.The integrated graph can provide support for a broader range of knowledge joint applications.
