摘要:

基于递归神经网络和Transformers架构的语言模型的最新进展已经在广泛的自然语言处理任务上取得了最先进的结果,例如pos标记,命名实体识别和文本分类。然而,这些语言模型中的大多数都是用高资源语言(如英语,德语,西班牙语)进行预训练的。多语言语言模型在其训练语料库中包括印地语、泰卢固语、孟加拉语等印度语言,但它们往往不能代表这些语言的语言特征,因为它们不是研究的主要语言。我们介绍HinFlair,这是一个语言表示模型(上下文字符串嵌入)预先训练的大型单语印地语语料库。在6个文本分类数据集和一个印地语依赖树库上进行了实验,以分析这些上下文化的印地语字符串嵌入的性能。结果表明,HinFlair在文本分类和pos标记等下游任务中的表现优于之前公开提供的最先进的预训练嵌入。此外,HinFlair与FastText嵌入相结合时,性能优于许多基于transformers的语言模型,特别是为印地语训练的。

英文摘要:

Recent advancements in language models based on recurrent neural networks and transformers architecture have achieved state-of-the-art results on a wide range of natural language processing tasks such as pos tagging, named entity recognition, and text classification. However, most of these language models are pre-trained in high resource languages like English, German, Spanish. Multi-lingual language models include Indian languages like Hindi, Telugu, Bengali in their training corpus, but they often fail to represent the linguistic features of these languages as they are not the primary language of the study. We introduce HinFlair, which is a language representation model (contextual string embeddings) pre-trained on a large monolingual Hindi corpus. Experiments were conducted on 6 text classification datasets and a Hindi dependency treebank to analyze the performance of these contextualized string embeddings for the Hindi language. Results show that HinFlair outperforms previous state-of-the-art publicly available pre-trained embeddings for downstream tasks like text classification and pos tagging. Also, HinFlair when combined with FastText embeddings outperforms many transformers-based language models trained particularly for the Hindi language.
