Relation extraction represents a fundamental component in the process of creating knowledge graphs, among other applications. Large language models (LLMs) have been adopted as a promising tool for relation extraction, both in supervised and in-context learning settings. However, in this work we show that their performance still lags behind much smaller architectures when the linguistic graph underlying a text has great complexity. To demonstrate this, we evaluate four LLMs against a graph-based parser on six relation extraction datasets with sentence graphs of varying sizes and complexities. Our results show that the graph-based parser increasingly outperforms the LLMs, as the number of relations in the input documents increases. This makes the much lighter graph-based parser a superior choice in the presence of complex linguistic graphs.

有间隔的句子,如Paul likes coffee and Mary tea,缺少一个显性谓词来表示两个或多个论元之间的关系。这样的句子的表面句法表示通常由解析器产生得很差,并且即使正确,也不能很好地适合于下游自然语言理解任务,例如通常被设计为从具有规范子句结构的句子中提取信息的关系抽取。在本文中,我们提出了两种方法来解析到一个通用的消隐图表示,显式编码的省略材料与额外的节点和边缘。我们发现,这两种方法可以重建省略材料的依赖树,具有高精度时,解析器正确预测存在的差距。我们进一步证明,我们的方法之一,可以适用于其他语言的基础上对瑞典语的案例研究。
