摘要:

嵌入是将实体从一个代数结构映射到另一个代数结构同时保留某些特征的函数。嵌入正被成功地用于将关系数据或文本映射到向量空间,在向量空间中它们可用于机器学习、相似性搜索或类似任务。我们解决的问题,找到向量空间嵌入的理论描述逻辑$\mathcal{EL}^{++}$,也是模型的TBox。为了找到这样的嵌入,我们定义了一个优化问题,其特征在于在$\Re^n$内的$\mathcal{EL}^{++}$的运营商的模型理论语义,从而解决了这个问题,找到一个解释功能的$\mathcal{EL}^{++}$理论给定一个特定的域$Δ$。我们的方法主要是相关的大型$\mathcal{EL}^{++}$理论和知识库,如本体和知识图谱在生命科学中使用。我们证明,与语义相似性度量或知识图谱嵌入相比,我们的方法可用于改进蛋白质-蛋白质相互作用的预测

英文摘要:

An embedding is a function that maps entities from one algebraic structure into another while preserving certain characteristics. Embeddings are being used successfully for mapping relational data or text into vector spaces where they can be used for machine learning, similarity search, or similar tasks. We address the problem of finding vector space embeddings for theories in the Description Logic $\mathcal{EL}^{++}$ that are also models of the TBox. To find such embeddings, we define an optimization problem that characterizes the model-theoretic semantics of the operators in $\mathcal{EL}^{++}$ within $\Re^n$, thereby solving the problem of finding an interpretation function for an $\mathcal{EL}^{++}$ theory given a particular domain $Δ$. Our approach is mainly relevant to large $\mathcal{EL}^{++}$ theories and knowledge bases such as the ontologies and knowledge graphs used in the life sciences. We demonstrate that our method can be used for improved prediction of protein--protein interactions when compared to semantic similarity measures or knowledge graph embedding
