While human values play a crucial role in making arguments persuasive, we currently lack the necessary extensive datasets to develop methods for analyzing the values underlying these arguments on a large scale. To address this gap, we present the Touché23-ValueEval dataset, an expansion of the Webis-ArgValues-22 dataset. We collected and annotated an additional 4780 new arguments, doubling the dataset’s size to 9324 arguments. These arguments were sourced from six diverse sources, covering religious texts, community discussions, free-text arguments, newspaper editorials, and political debates. Each argument is annotated by three crowdworkers for 54 human values, following the methodology established in the original dataset. The Touché23-ValueEval dataset was utilized in the SemEval 2023 Task 4. ValueEval: Identification of Human Values behind Arguments, where an ensemble of transformer models demonstrated state-of-the-art performance. Furthermore, our experiments show that a fine-tuned large language model, Llama-2-7B, achieves comparable results.

In this study, we address the linguistic challenges posed by Tajiki Persian, a distinct variant of the Persian language that utilizes the Cyrillic script due to historical “Russification”. This distinguishes it from other Persian dialects that adopt the Arabic script. Despite its profound linguistic and cultural significance, Tajiki Persian remains a low-resource language with scant digitized datasets for computational applications. To address this deficiency, we created a parallel corpus using Shahnameh, a seminal Persian epic poem. Employing optical character recognition, we extracted Tajiki Persian verses from primary sources and applied a heuristic method to align them with their Iranian Persian counterparts. We then trained and assessed transliteration models using two prominent sequence-to-sequence architectures: GRU with attention and transformer. Our results underscore the enhanced performance of our models, particularly in contrast to pre-trained large multilingual models like GPT-3.5, emphasizing the value of dedicated datasets in advancing computational approaches for underrepresented languages. With the publication of this work, we are disseminating, for the first time, a vast collection of Persian poetry spanning 1000 years, transcribed in Tajiki scripts for the benefit of the Tajiki-speaking communities. The dataset, along with the model’s code and checkpoints, is accessible at https://github.com/language-ml/Tajiki-Shahname, marking a significant contribution to computational linguistic resources for Tajiki Persian.
