多任务领域自适应序列标记

Multi-task Domain Adaptation for Sequence Tagging

Johns Hopkins University(约翰斯·霍普金斯大学)

Nanyun Peng, Mark Dredze

摘要:

许多领域自适应方法依赖于学习跨领域共享表示,以将在一个领域中学习到的知识转移到其他领域。传统的领域自适应只考虑适应一个任务。在本文中,我们探讨了多任务表示学习下的领域自适应的情况。我们提出了一个神经网络框架,支持领域自适应多个任务同时进行,并学习共享表示,更好地概括领域自适应。我们将所提出的框架应用于序列标记问题的领域自适应,考虑两个任务:中文分词和命名实体识别。实验结果表明,对于每个任务,多任务领域自适应都比不相交的领域自适应更有效,并且在社交媒体领域,两种任务都达到了最佳效果。

英文摘要:

Many domain adaptation approaches rely on learning cross domain shared representations to transfer the knowledge learned in one domain to other domains. Traditional domain adaptation only considers adapting for one task. In this paper, we explore multi-task representation learning under the domain adaptation scenario. We propose a neural network framework that supports domain adaptation for multiple tasks simultaneously, and learns shared representations that better generalize for domain adaptation. We apply the proposed framework to domain adaptation for sequence tagging problems considering two tasks: Chinese word segmentation and named entity recognition. Experiments show that multi-task domain adaptation works better than disjoint domain adaptation for each task, and achieves the state-of-the-art results for both tasks in the social media domain.
