描述逻辑是一类基于逻辑的知识表示形式，它可以用于以形式上有根据的方式开发本体。包含的标准推理服务在本体设计和维护中是不可或缺的。相对于本体中的逻辑定义，这检查一个概念是否比另一个概念更一般/具体。然而，当没有确定包含关系时，就不能给出关于这两个概念的信息。这项工作提出了一个新的概念，语义相似性源于已知的同态为基础的结构包容算法。建议的相似性度量计算两个EL概念描述之间的数值相似度，尽管不是在包容关系。
Description Logics (DLs) are a family of logic-based knowledge representation formalisms, which can be used to develop ontologies in a formally well-founded way. The standard reasoning service of subsumption has proved indispensable in ontology design and maintenance. This checks, relative to the logical definitions in the ontology, whether one concept is more general/specific than another. When no subsumption relationship is identified, however, no information about the two concepts can be given. This work presents a new notion of semantic similarity which stems from the known homomorphism-based structural subsumption algorithm. The proposed similarity measure computes a numerical degree of similarity between two EL concept descriptions despite not being in the subsumption relation.
