摘要:

虽然有一个新兴的趋势,主要是为非结构化数据生成嵌入,最近,结构化数据,还没有系统的套件,用于测量嵌入的质量已经提出。这种缺陷在为结构化数据生成的嵌入方面进一步被感知,因为没有具体的评估度量来测量编码结构的质量以及嵌入空间中的语义模式。在本文中,我们介绍了一个框架,包含三个不同的任务与本体概念的各个方面:(i)范畴化方面,(ii)层次方面,(iii)关系方面。然后,在每个任务的范围内,提出了一些内在的指标来评估嵌入的质量。此外,W.R.T.在此框架下,进行了多项实验研究,以比较可用嵌入模型的质量。在未来的研究中使用这个框架可以减少误判,并提供更深入的了解嵌入本体概念的质量比较。我们在GNU通用公共许可证v3.0下将采样数据和代码放置在https://github.com/alshargi/Concept2vec上。

英文摘要:

Although there is an emerging trend towards generating embeddings for primarily unstructured data and, recently, for structured data, no systematic suite for measuring the quality of embeddings has been proposed yet. This deficiency is further sensed with respect to embeddings generated for structured data because there are no concrete evaluation metrics measuring the quality of the encoded structure as well as semantic patterns in the embedding space. In this paper, we introduce a framework containing three distinct tasks concerned with the individual aspects of ontological concepts: (i) the categorization aspect, (ii) the hierarchical aspect, and (iii) the relational aspect. Then, in the scope of each task, a number of intrinsic metrics are proposed for evaluating the quality of the embeddings. Furthermore, w.r.t. this framework, multiple experimental studies were run to compare the quality of the available embedding models. Employing this framework in future research can reduce misjudgment and provide greater insight about quality comparisons of embeddings for ontological concepts.
