Simple ontology alignments, largely studied in the literature, link a single entity of a source ontology to a single entity of a target ontology. A limitation of these alignments is their lack of expressiveness which can be overcome by complex alignments. While diverse state-of-the-art surveys mainly review the matching approaches in general, to the best of our knowledge, there is no study of the specificities of the complex matching problem. In this paper, a review of the different complex matching approaches is provided. It proposes a classification of the complex matching approaches based on their specificities (i.e., type of correspondences, guiding structure). The evaluation aspects and the limitations of these approaches are also discussed. Insights for future work in the field are provided.

复杂本体匹配研究

在文献中进行了大量研究的简单本体比对将源本体的单个实体与目标本体的单个实体链接在一起。这些比对的局限性是它们缺乏表达能力，可以通过复杂的比对来克服。尽我们所知，虽然各种各样的最新调查通常都在总体上回顾匹配方法，但据我们所知，还没有研究复杂匹配问题的特殊性。本文对不同的复杂匹配方法进行了综述。它提出了基于复杂匹配方法的特性（即对应类型，指导结构）的分类。还讨论了这些方法的评估方面和局限性。提供了对该领域未来工作的见解。
