We present TwHIN-BERT, a multilingual language model trained on in-domain data from the popular social network Twitter. TwHIN-BERT differs from prior pre-trained language models as it is trained with not only text-based self-supervision, but also with a social objective based on the rich social engagements within a Twitter heterogeneous information network (TwHIN). Our model is trained on 7 billion tweets covering over 100 distinct languages providing a valuable representation to model short, noisy, user-generated text. We evaluate our model on a variety of multilingual social recommendation and semantic understanding tasks and demonstrate significant metric improvement over established pre-trained language models. We will freely open-source TwHIN-BERT and our curated hashtag prediction and social engagement benchmark datasets to the research community.

TwHIN-BERT是一种多语言语言模型，使用来自Twitter的专业领域数据进行训练，并通过具有基于Twitter异构信息网络（TwHIN）中丰富的社交互动的社交目标的训练使其不同于以前的预训练语言模型。我们在各种多语言社交推荐和语义理解任务上评估了我们的模型，并展示了相对于已建立的预训练语言模型的重大指标改进。
