摘要:

由于数据通常存储在不同的源中,因此需要将其集成以收集所需的全局视图,以便从中创造价值并获取知识。数据集成的关键步骤是模式匹配,其目的是找到两个模式元素之间的语义对应关系。为了减少模式匹配中涉及的手动工作,已经开发了许多用于模式对应的自动确定的解决方案。在本文中,我们提出了一种新的端到端的模式匹配方法的基础上神经嵌入。主要思想是使用两步方法,包括表匹配步骤和属性匹配步骤。在这两个步骤中,我们使用不同级别的嵌入,表示整个表或单个属性。我们的研究结果表明,我们的方法是能够确定的对应关系,在一个强大的和可靠的方式相比,传统的模式匹配方法可以找到非平凡的对应关系。

英文摘要:

Since data is often stored in different sources, it needs to be integrated to gather a global view that is required in order to create value and derive knowledge from it. A critical step in data integration is schema matching which aims to find semantic correspondences between elements of two schemata. In order to reduce the manual effort involved in schema matching, many solutions for the automatic determination of schema correspondences have already been developed. In this paper, we propose a novel end-to-end approach for schema matching based on neural embeddings. The main idea is to use a two-step approach consisting of a table matching step followed by an attribute matching step. In both steps we use embeddings on different levels either representing the whole table or single attributes. Our results show that our approach is able to determine correspondences in a robust and reliable way and compared to traditional schema matching approaches can find non-trivial correspondences.
