摘要
摘要:本体作为指导知识图谱数据构建的上层结构,在知识图谱技术中具有重要意义。本体在发展的过程中会形成结构上的冗余。现有的本体消冗方法无法处理含有等价关系的本体结构,只能针对单一类属关系进行冗余的检测与消除。该文针对含有等价关系的本体提出一种基于超节点理论的消冗算法,首先将相互等价的节点看作超节点,消除单一类属关系之间的的冗余;然后还原等价节点,消除等价关系与类属关系之间的冗余。在计算机生成网络和真实网络上的实验和分析表明,该算法能够准确识别关系冗余,具有较高的稳定性和综合性能。

Abstract:Ontology, as the superstructure of knowledge graph, has great significance in knowledge graph domain. In general, structural redundancy may arise in ontology evolution. Most of existing redundancy elimination algorithms focus on transitive redundancies while ignore equivalent relations. Focusing on this problem, a redundancy elimination algorithm based on super-node theory is proposed. Firstly, the nodes equivalent to each other are considered as a super-node to transfer the ontology into a directed acyclic graph. Thus the redundancies relating to transitive relations can be eliminated by existing methods. Then equivalent relations are restored, and the redundancies between equivalent and transitive relations are eliminated. Experiments on both synthetic dynamic networks and real networks indicate that the proposed algorithm can detect redundant relations precisely, with better performance and stability compared with the benchmarks.
