摘要:
对于以往基于多类分类、MASK预测或原型匹配的方法而言,抽取偏离已知模式的事件关系已被证明具有挑战性。大语言模型的最新进展通过指令微调展现出了令人瞩目的性能。然而,在事件关系抽取任务中,基于指令的方法面临若干挑战:推理样本数量庞大,且事件之间的关系是非顺序的。为应对这些挑战,我们提出了一种改进的基于指令的事件关系抽取框架,名为MAQInstruct。首先,我们将任务从使用给定的事件-事件指令抽取事件关系,转变为使用给定的事件-关系指令选择事件,从而减少了推理所需的样本数量。然后,通过引入二分匹配损失,我们降低了基于指令的方法对生成顺序的依赖。我们的实验结果表明,MAQInstruct在多个大语言模型上显著提升了事件关系抽取的性能。
英文摘要:
Extracting event relations that deviate from known schemas has proven challenging for previous methods based on multi-class classification, MASK prediction, or prototype matching. Recent advancements in large language models have shown impressive performance through instruction tuning. Nevertheless, in the task of event relation extraction, instruction-based methods face several challenges: there are a vast number of inference samples, and the relations between events are non-sequential. To tackle these challenges, we present an improved instruction-based event relation extraction framework named MAQInstruct. Firstly, we transform the task from extracting event relations using given event-event instructions to selecting events using given event-relation instructions, which reduces the number of samples required for inference. Then, by incorporating a bipartite matching loss, we reduce the dependency of the instruction-based method on the generation sequence. Our experimental results demonstrate that MAQInstruct significantly improves the performance of event relation extraction across multiple LLMs.
