摘要:

我们研究多任务学习(MTL)是否以及在哪里可以提高与论证挖掘(AM)相关的NLP问题的性能,特别是论证组件识别。我们的研究结果表明,MTL表现得特别好(优于单任务学习)时,很少训练数据可用于主任务,在AM中的常见情况。我们的研究结果挑战了以前的假设,即AM数据集的概念化是发散的,MTL对于语义或更高级别的任务是困难的。

英文摘要:

We investigate whether and where multi-task learning (MTL) can improve performance on NLP problems related to argumentation mining (AM), in particular argument component identification. Our results show that MTL performs particularly well (and better than single-task learning) when little training data is available for the main task, a common scenario in AM. Our findings challenge previous assumptions that conceptualizations across AM datasets are divergent and that MTL is difficult for semantic or higher-level tasks.
