AI总结:

针对中文多模态命名实体识别数据不足的问题,本文构建含5,000条微博与18,326张图像的CMNER数据集,并通过基线与跨语言实验验证图像融合及中英数据互促的有效性。

摘要:

多模态命名实体识别(MNER)是一项关键任务,旨在借助相关图像从文本中抽取命名实体。然而,中文MNER数据的显著匮乏在很大程度上阻碍了这一自然语言处理任务在中文领域的进展。因此,本研究利用来自中国最大社交媒体平台微博的数据,构建了一个中文多模态NER数据集(CMNER)。该数据集包含5,000条微博帖子,并配有18,326张相应图像。实体被划分为四个不同类别:人物、地点、组织机构和杂项。我们在CMNER上进行了基线实验,结果强调了引入图像对NER的有效性。此外,我们还在公开可用的英文MNER数据集(Twitter2015)上开展了跨语言实验,结果证实了我们的假设,即中文和英文多模态NER数据能够相互提升NER模型的性能。

英文摘要:

Multimodal Named Entity Recognition (MNER) is a pivotal task designed to extract named entities from text with the support of pertinent images. Nonetheless, a notable paucity of data for Chinese MNER has considerably impeded the progress of this natural language processing task within the Chinese domain. Consequently, in this study, we compile a Chinese Multimodal NER dataset (CMNER) utilizing data sourced from Weibo, China's largest social media platform. Our dataset encompasses 5,000 Weibo posts paired with 18,326 corresponding images. The entities are classified into four distinct categories: person, location, organization, and miscellaneous. We perform baseline experiments on CMNER, and the outcomes underscore the effectiveness of incorporating images for NER. Furthermore, we conduct cross-lingual experiments on the publicly available English MNER dataset (Twitter2015), and the results substantiate our hypothesis that Chinese and English multimodal NER data can mutually enhance the performance of the NER model.
