摘要:

模式匹配是任何数据集成过程的核心任务。在数据库、人工智能、语义Web和数据采掘领域研究多年,主要挑战仍然是在数据概念之间生成质量匹配的能力(例如,数据库属性)。在这项工作中,我们研究了一个新的角度对人类的行为匹配,研究匹配创建的过程。我们分析了常见的评价指标(精度,召回率和f-测量)的动态,相对于这个角度,并强调需要无偏匹配,以支持这种分析。无偏匹配,一个新定义的概念,描述了共同的假设,人类的决定代表可靠的评估模式对应,但是,不是一个固有的属性的人类匹配。在下文中,我们设计了PoWareMatch,其利用深度学习机制来校准和过滤遵循匹配质量的人类匹配决策,然后将其与算法匹配相结合以生成更好的匹配结果。我们提供了一个经验证据,建立在一个实验的基础上,超过200人类匹配超过共同的基准,PoWareMatch预测以及扩展匹配的好处与额外的对应关系,并产生高质量的匹配。此外,PoWareMatch的性能优于最先进的匹配算法。

英文摘要:

Schema matching is a core task of any data integration process. Being investigated in the fields of databases, AI, Semantic Web and data mining for many years, the main challenge remains the ability to generate quality matches among data concepts (e.g., database attributes). In this work, we examine a novel angle on the behavior of humans as matchers, studying match creation as a process. We analyze the dynamics of common evaluation measures (precision, recall, and f-measure), with respect to this angle and highlight the need for unbiased matching to support this analysis. Unbiased matching, a newly defined concept that describes the common assumption that human decisions represent reliable assessments of schemata correspondences, is, however, not an inherent property of human matchers. In what follows, we design PoWareMatch that makes use of a deep learning mechanism to calibrate and filter human matching decisions adhering the quality of a match, which are then combined with algorithmic matching to generate better match results. We provide an empirical evidence, established based on an experiment with more than 200 human matchers over common benchmarks, that PoWareMatch predicts well the benefit of extending the match with an additional correspondence and generates high quality matches. In addition, PoWareMatch outperforms state-of-the-art matching algorithms.
