摘要:

语言在社交媒体数据中的用户和他们感兴趣的领域之间变化:用户在他/她的兴趣中创作的词可能具有不同的含义(例如,酷)或情绪(例如,快)。然而,大多数现有的训练用户嵌入的方法忽略了用户兴趣之间的变化,例如产品和电影类别(例如,戏剧与动作)。在这项研究中,我们把用户的兴趣作为域,并实证研究如何在三个英语社交媒体数据集的用户因素的用户语言可以变化。然后,我们提出了一个用户嵌入模型,通过多任务学习框架来考虑用户兴趣的语言变异性。该模型在没有人类监督的情况下学习用户语言及其变体。虽然现有的工作主要是评估用户嵌入的外在任务,我们提出了一个内在的评价,通过聚类和评估用户嵌入的外在任务,文本分类。在三个英语社交媒体数据集上的实验表明,我们提出的方法通常可以通过调整用户因素来超越基线。

英文摘要:

Language varies across users and their interested fields in social media data: words authored by a user across his/her interests may have different meanings (e.g., cool) or sentiments (e.g., fast). However, most of the existing methods to train user embeddings ignore the variations across user interests, such as product and movie categories (e.g., drama vs. action). In this study, we treat the user interest as domains and empirically examine how the user language can vary across the user factor in three English social media datasets. We then propose a user embedding model to account for the language variability of user interests via a multitask learning framework. The model learns user language and its variations without human supervision. While existing work mainly evaluated the user embedding by extrinsic tasks, we propose an intrinsic evaluation via clustering and evaluate user embeddings by an extrinsic task, text classification. The experiments on the three English-language social media datasets show that our proposed approach can generally outperform baselines via adapting the user factor.
