Bilingual resources for Moroccan Sign Language Generation and Standard Arabic Skills Improvement of Deaf Children (2025)

This paper presents a set of bilingual Standard Arabic (SA)-Moroccan Sign Language (MSL) tools and resources to improve Moroccan Deaf children`s SA skills. An MSL Generator based on rule-based machine translation (MT) is described that enables users and educators of Deaf children, in particular, to enter Arabic text and generate its corresponding MSL translation in both graphic and video format. The generated graphics can be printed and imported into an Arabic reading passage. We have also developed MSL Clip and Create software that includes a bilingual database of 3,000 MSL signs and SA words, a Publisher for the incorporation of MSL graphic support into SA reading passages, and six Templates that create customized bilingual crossword puzzles, word searches, Bingo cards, matching games, flashcards, and fingerspelling scrambles. A crowdsourcing platform for MSL data collection is also described. A major social benefit of the development of these resources is in relation to equity and the status of deaf people in Moroccan society. More appropriate resources for the bilingual education of Deaf children (in MSL and SA) will lead to improved quality of educational services.
Harmonizing Annotation of Turkic Postverbial Constructions: A Comparative Study of UD Treebanks (2025)

As the number of treebanks within the same language family continues to grow, the importance of establishing consistent annotation practices has become increasingly evident. In this paper, we evaluate various approaches to annotating Turkic postverbial constructions across UD treebanks. Our comparative analysis reveals that none of the existing methods fully capture the unique semantic and syntactic characteristics of these complex constructions. This underscores the need to adopt a balanced approach that can achieve broad consensus and be implemented consistently across Turkic treebanks. By examining the phenomenon and the available annotation strategies, our study aims to improve the consistency of Turkic UD treebanks and enhance their utility for cross-linguistic research.
Towards Truly Open, Language-Specific, Safe, Factual, and Specialized Large Language Models (2025)

First, we will argue for the need for fully transparent open-source large language models (LLMs), and we will describe the efforts of MBZUAI`s Institute on Foundation Models (IFM) towards that based on the LLM360 initiative. Second, we will argue for the need for language-specific LLMs, and we will share our experience from building Jais, the world`s leading open Arabic-centric foundation and instruction-tuned large language model, Nanda, our recently released open Hindi LLM, and some other models. Third, we will argue for the need for safe LLMs, and we will present Do-Not-Answer, a dataset for evaluating the guardrails of LLMs, which is at the core of the safety mechanisms of our LLMs. Forth, we will argue for the need for factual LLMs, we will discuss the factuality challenges that LLMs pose. We will then present some recent relevant tools for addressing these challenges developed at MBZUAI: (i) OpenFactCheck, a framework for fact-checking LLM output, for building customized fact-checking systems, and for benchmarking LLMs for factuality, (ii) LM-Polygraph, a tool for predicting an LLM`s uncertainty in its output using cheap and fast uncertainty quantification techniques, and (iii) LLM-DetectAIve, a tool for machine-generated text detection. Finally, we will argue for the need for specialized models, and we will present the zoo of LLMs currently being developed at MBZUAI`s IFM.
Make Satire Boring Again: Reducing Stylistic Bias of Satirical Corpus by Utilizing Generative LLMs (2025)

Satire detection is essential for accurately extracting opinions from textual data and combating misinformation online. However, the lack of diverse corpora for satire leads to the problem of stylistic bias which impacts the models' detection performances. This study proposes a debiasing approach for satire detection, focusing on reducing biases in training data by utilizing generative large language models. The approach is evaluated in both cross-domain (irony detection) and cross-lingual (English) settings. Results show that the debiasing method enhances the robustness and generalizability of the models for satire and irony detection tasks in Turkish and English. However, its impact on causal language models, such as Llama-3.1, is limited. Additionally, this work curates and presents the Turkish Satirical News Dataset with detailed human annotations, with case studies on classification, debiasing, and explainability.
BEIR-NL: Zero-shot Information Retrieval Benchmark for the Dutch Language (2025)

Zero-shot evaluation of information retrieval (IR) models is often performed using BEIR; a large and heterogeneous benchmark composed of multiple datasets, covering different retrieval tasks across various domains. Although BEIR has become a standard benchmark for the zero-shot setup, its exclusively English content reduces its utility for underrepresented languages in IR, including Dutch. To address this limitation and encourage the development of Dutch IR models, we introduce BEIR-NL by automatically translating the publicly accessible BEIR datasets into Dutch. Using BEIR-NL, we evaluated a wide range of multilingual dense ranking and reranking models, as well as the lexical BM25 method. Our experiments show that BM25 remains a competitive baseline, and is only outperformed by the larger dense models trained for retrieval. When combined with reranking models, BM25 achieves performance on par with the best dense ranking models. In addition, we explored the impact of translation on the data by back-translating a selection of datasets to English, and observed a performance drop for both dense and lexical methods, indicating the limitations of translation for creating benchmarks. BEIR-NL is publicly available on the Hugging Face hub.
Refining Dimensions for Improving Clustering-based Cross-lingual Topic Models (2025)

Recent works in clustering-based topic models perform well in monolingual topic identification by introducing a pipeline to cluster the contextualized representations. However, the pipeline is suboptimal in identifying topics across languages due to the presence of language-dependent dimensions (LDDs) generated by multilingual language models. To address this issue, we introduce a novel, SVD-based dimension refinement component into the pipeline of the clustering-based topic model. This component effectively neutralizes the negative impact of LDDs, enabling the model to accurately identify topics across languages. Our experiments on three datasets demonstrate that the updated pipeline with the dimension refinement component generally outperforms other state-of-the-art cross-lingual topic models.
The Role of Handling Attributive Nouns in Improving Chinese-To-English Machine Translation (2025)

Translating between languages with drastically different grammatical conventions poses significant challenges, not just for human interpreters but also for machine translation systems. In this work, we specifically target the translation challenges posed by attributive nouns in Chinese, which frequently cause ambiguities in English translation. By manually inserting the omitted particle {\textquoteleft}DE' in news article titles from the Penn Chinese Discourse Treebank, we developed a targeted dataset to fine-tune Hugging Face Chinese to English translation models, specifically improving how this critical function word is handled. This focused approach not only complements the broader strategies suggested by previous studies but also offers a practical enhancement by specifically addressing a common error type in Chinese-English translation.
Can a Neural Model Guide Fieldwork? A Case Study on Morphological Data Collection (2025)

Linguistic fieldwork is an important component in language documentation and the creation of comprehensive linguistic corpora. Despite its significance, the process is often lengthy, exhaustive, and time-consuming. This paper presents a novel model that guides a linguist during the fieldwork and accounts for the dynamics of linguist-speaker interactions. We introduce a novel framework that evaluates the efficiency of various sampling strategies for obtaining morphological data and assesses the effectiveness of state-of-the-art neural models in generalising morphological structures. Our experiments highlight two key strategies for improving the efficiency: (1) increasing the diversity of annotated data by uniform sampling among the cells of the paradigm tables, and (2) using model confidence as a guide to enhance positive interaction by providing reliable predictions during annotation.
Comparable Corpora: Opportunities for New Research Directions (2025)

Most conference papers present new results, but this paper will focus more on opportunities for the audience to make their own contributions. This paper is intended to challenge the community to think more broadly about what we can do with comparable corpora. We will start with a review of the history, and then suggest new directions for future research.
SELEXINI -- a large and diverse automatically parsed corpus of French (2025)

The annotation of large text corpora is essential for many tasks. We present here a large automatically annotated corpus for French. This corpus is separated into two parts: the first from BigScience, and the second from HPLT. The annotated documents from HPLT were selected in order to optimise the lexical diversity of the final corpus SELEXINI. An analysis of the impact of this selection was carried out on syntactic diversity, as well as on the quality of the new words resulting from the HPLT part of SELEXINI. We have shown that despite the introduction of interesting new words, the texts extracted from HPLT are very noisy. Furthermore, increasing lexical diversity did not increase syntactic diversity.
Text-to-speech system for low-resource languages: A case study in Shipibo-Konibo (a Panoan language from Peru) (2025)

This paper presents the design and development of a Text-to-Speech (TTS) model for Shipibo-Konibo, a low-resource indigenous language spoken mainly in the Peruvian Amazon. Despite the challenge posed by the scarcity of data, the model was trained with over 4 hours of recordings and 3,025 meticulously collected written sentences. The tests results demon strated an intelligibility rate (IR) exceeding 88{\%} and a mean opinion score (MOS) of 4.01, confirming the quality of the audio generated by the model, which comprises the Tacotron 2 spectrogram predictor and the HiFi-GAN vocoder. Furthermore, the potential of this model to be trained in other indigenous languages spoken in Peru is highlighted, opening a promising avenue for the documentation and revitalization of these languages.
Does a code-switching dialogue system help users learn conversational fluency in Choctaw? (2025)

We investigate the learning outcomes and user response to a chatbot for practicing conversational Choctaw, an endangered American Indigenous language. Conversational fluency is a goal for many language learners, however, for learners of endangered languages in North America, access to fluent speakers may be limited. Chatbots are potentially ideal dialogue partners as this kind of dialogue system fulfills a non-authoritative role by focusing on carrying on a conversation as an equal conversational partner. The goal of the chatbot investigated in this work is to serve as a conversational partner in the absence of a fluent Choctaw-speaking human interlocutor. We investigate the impact of code-switching in the interaction, comparing a bilingual chatbot against a monolingual Choctaw version. We evaluate the systems for user engagement and enjoyment, as well as gains in conversational fluency from interacting with the system.
A hybrid Approach to low-resource machine translation for Ojibwe verbs (2025)

Machine translation is a tool that can help teachers, learners, and users of low-resourced languages. However, there are significant challenges in developing these tools, such as the lack of large-scale parallel corpora and complex morphology. We propose a novel hybrid system that combines LLM and rule-based methods in two distinct stages to translate inflected Ojibwe verbs into English. We use an LLM to automatically annotate dictionary data to build translation templates. Then, our rulebased module performs translation using inflection and slot-filling processes built on top of an FST-based analyzer. We test the system with a set of automated tests. Thanks to the ahead-of-time nature of the template-building process and the light-weight rule-based translation module, the end-to-end translation process has an average translation speed of 70 milliseconds per word. The system achieved an average ChrF score of 0.82 and a semantic similarity score of 0.93 among the successfully translated verbs in a test set. The approach has the potential to be extended to other low-resource Indigenous languages with dictionary data.
Advancing Uto-Aztecan Language Technologies: A Case Study on the Endangered Comanche Language (2025)

The digital exclusion of endangered languages remains a critical challenge in NLP, limiting both linguistic research and revitalization efforts. This study introduces the first computational investigation of Comanche, an Uto-Aztecan language on the verge of extinction, demonstrating how minimal-cost, community-informed NLP interventions can support language preservation. We present a manually curated dataset of 412 phrases, a synthetic data generation pipeline, and an empirical evaluation of GPT-4o and GPT-4o-mini for language identification. Our experiments reveal that while LLMs struggle with Comanche in zero-shot settings, few-shot prompting significantly improves performance, achieving near-perfect accuracy with just five examples. Our findings highlight the potential of targeted NLP methodologies in low-resource contexts and emphasize that visibility is the first step toward inclusion. By establishing a foundation for Comanche in NLP, we advocate for computational approaches that prioritize accessibility, cultural sensitivity, and community engagement.
Py-Elotl: A Python NLP package for the languages of Mexico (2025)

This work presents Py-elotl, a suite of tools and resources in Python for processing text in several indigenous languages spoken in Mexico. These resources include parallel corpora, linguistic taggers/analyzers, and orthographic normalization tools. This work aims to develop essential resources to support language pre-processing and linguistic research, and the future creation of more complete downstream applications that could be useful for the speakers and enhance the visibility of these languages. The current version supports language groups such as Nahuatl, Otomi, Mixtec, and Huave. This project is open-source and freely available for use and collaboration
Analyzing and generating English phrases with finite-state methods to match and translate inflected Plains Cree word-forms (2025)

This paper presents two finite-state transducer tools, which can be used to analyze or generate simple English verb and noun phrases, that can be mapped with inflected Plains Cree (n{\^e}hiyaw{\^e}win) verb and noun forms. These tools support fetching an inflected Cree word-form directly with an appropriate plain English phrase, and conversely providing a rough translation of an inflected Cree word-form. Such functionalities can be used to improve the user friendliness of on-line dictionaries. The tools are extendable to other similarly morphologically complex languages.
Unsupervised, Semi-Supervised and LLM-Based Morphological Segmentation for Bribri (2025)

Morphological Segmentation is a major task in Indigenous language documentation. In this paper we (a) introduce a novel statistical algorithm called Morphemo to split words into their constituent morphemes. We also (b) study how large language models perform on this task. We use these tools to analyze Bribri, an under-resourced Indigenous language from Costa Rica. Morphemo has better performance than the LLM when splitting multimorphemic words, mainly because the LLMs are more conservative, which also gives them an advantage when splitting monomorphemic words. In future work we will use these tools to tag Bribri language corpora, which currently lack morphological segmentation.
FUSE : A Ridge and Random Forest-Based Metric for Evaluating MT in Indigenous Languages (2025)

This paper presents the winning submission of the RaaVa team to the AmericasNLP 2025 Shared Task 3 on Automatic Evaluation Metrics for Machine Translation (MT) into Indigenous Languages of America, where our system ranked first overall based on average Pearson correlation with the human annotations. We introduce Feature-Union Scorer (FUSE) for Evaluation, FUSE integrates Ridge regression and Gradient Boosting to model translation quality. In addition to FUSE, we explore five alternative approaches leveraging different combinations of linguistic similarity features and learning paradigms. FUSE Score highlights the effectiveness of combining lexical, phonetic, semantic, and fuzzy token similarity with learning-based modeling to improve MT evaluation for morphologically rich and low-resource languages. MT into Indigenous languages poses unique challenges due to polysynthesis, complex morphology, and non-standardized orthography. Conventional automatic metrics such as BLEU, TER, and ChrF often fail to capture deeper aspects like semantic adequacy and fluency. Our proposed framework, formerly referred to as FUSE, incorporates multilingual sentence embeddings and phonological encodings to better align with human evaluation. We train supervised models on human-annotated development sets and evaluate held-out test data. Results show that FUSE consistently achieves higher Pearson and Spearman correlations with human judgments, offering a robust and linguistically informed solution for MT evaluation in low-resource settings.
UCSP Submission to the AmericasNLP 2025 Shared Task (2025)

Quechua is a low-resource language spoken by more than 7 million people in South America. While Quechua is primarily an oral language, several orthographic standards do exist. There is no universally adopted writing standard for Quechua, and variations exist across dialects and regions; its current writing is based on how it is uttered and how the sound is written. Quechua is a family of languages with similarities among the seven variants. The lack of a parallel dataset has reduced the opportunities for developing machine translation. We investigated whether increasing the current Quechua Parallel dataset with synthetic sentences and using a pre-trained large language model improves the performance of a Quechua machine translation. A Large language model has been used to generate synthetic sentences to extend the current parallel dataset. We use the mt5 model to fine-tune it to develop a machine translation for Quechua to Spanish and vice versa. Our survey identified the gaps in the state of the art of Quechua machine translation, and our BLEU/Chrf++ results show an improvement over the state of the art.
Machine Translation Using Grammar Materials for LLM Post-Correction (2025)

This paper describes George Mason University`s submission to the AmericasNLP 2025 Shared Task on Machine Translation into Indigenous Languages. We prompt a large language model (LLM) with grammar reference materials to correct the translations produced by a finetuned Encoder-Decoder machine translation system. This system leads to improvements when translating from the indigenous languages into Spanish indicating that LLMs are capable of using grammar materials to decipher an unseen language.
Machine Translation Metrics for Indigenous Languages Using Fine-tuned Semantic Embeddings (2025)

This paper describes the Tekio submission to the AmericasNLP 2025 shared task on machine translation metrics for Indigenous languages. We developed two primary metric approaches leveraging multilingual semantic embeddings. First, we fine-tuned the Language-agnostic BERT Sentence Encoder (LaBSE) specifically for Guarani, Bribri, and Nahuatl, significantly enhancing semantic representation quality. Next, we integrated our fine-tuned LaBSE into the semantic similarity metric YiSi-1, exploring the effectiveness of averaging multiple layers. Additionally, we trained regression-based COMET metrics (COMET-DA) using the fine-tuned LaBSE embeddings as a semantic backbone, comparing Mean Absolute Error (MAE) and Mean Squared Error (MSE) loss functions. Our YiSi-1 metric using layer-averaged embeddings chosen by having the best performance on the development set for each individual language achieved the highest average correlation across languages among our submitted systems, and our COMET models demonstrated competitive performance for Guarani.
JHU`s Submission to the AmericasNLP 2025 Shared Task on the Creation of Educational Materials for Indigenous Languages (2025)

This paper presents JHU`s submission to the AmericasNLP shared task on the creation of educational materials for Indigenous languages. The task involves transforming a base sentence given one or more tags that correspond to grammatical features, such as negation or tense. The task also spans four languages: Bribri, Maya, Guaran{\'i}, and Nahuatl. We experiment with augmenting prompts to large language models with different information, chain of thought prompting, ensembling large language models by majority voting, and training a pointer-generator network. Our System 1, an ensemble of large language models, achieves the best performance on Maya and Guaran{\'i}, building upon the previous successes in leveraging large language models for this task and highlighting the effectiveness of ensembling large language models.
Leveraging Dictionaries and Grammar Rules for the Creation of Educational Materials for Indigenous Languages (2025)

This paper describes the NAIST submission to the AmericasNLP 2025 shared task on the creation of educational materials for Indigenous languages. We implement three systems to tackle the unique challenges of each language. The first system, used for Maya and Guarani, employs a straightforward GPT-4o few-shot prompting technique, enhanced by synthetically generated examples to ensure coverage of all grammatical variations encountered. The second system, used for Bribri, integrates dictionary-based alignment and linguistic rules to systematically manage linguisticand lexical transformations. Finally, we developed a specialized rule-based system for Nahuatl that systematically reduces sentences to their base form, simplifying the generation of correct morphology variants.
