Corpus Linguistics

In this paper we present our submission for the NorSID Shared Task as part of the 2025 VarDial Workshop (Scherrer et al., 2025), consisting of three tasks: Intent Detection, Slot Filling and Dialect Identification, evaluated using data in different dialects of the Norwegian language. For Intent Detection and Slot Filling, we have fine-tuned a multitask model in a cross-lingual setting, to leverage the xSID dataset available in 17 languages. In the case of Dialect Identification, our final submission consists of a model fine-tuned on the provided development set, which has obtained the highest scores within our experiments. Our final results on the test set show that our models do not drop in performance compared to the development set, likely due to the domain-specificity of the dataset and the similar distribution of both subsets. Finally, we also report an in-depth analysis of the provided datasets and their artifacts, as well as other sets of experiments that have been carried out but did not yield the best results. Additionally, we present an analysis on the reasons why some methods have been more successful than others; mainly the impact of the combination of languages and domain-specificity of the training data on the results.

In the context of the CALAMITA Challenge, we investigate the physical commonsense reasoning capabilities of large language models (LLMs) and introduce a methodology to assess their understanding of the physical world. To this end, we use a test set designed to evaluate physical commonsense reasoning in LLMs for the Italian language. We present a tiered dataset, named the Graded Italian Annotated dataset (GITA), which is written and annotated by a professional linguist. This dataset enables us to focus on three distinct levels of commonsense understanding. Our benchmark aims to evaluate three specific tasks: identifying plausible and implausible stories within our dataset, identifying the conflict that generates an implausible story, and identifying the physical states that make a story implausible. We perform these tasks using LLAMA3, Gemma2 and Mistral. Our findings reveal that, although the models may excel at high-level classification tasks, their reasoning is inconsistent and unverifiable, as they fail to capture intermediate evidence.

Artikulu honetan Latxa hizkuntza-ereduak (HE) aurkeztuko ditugu, egun euskararako garatu diren HE handienak. Latxa HEek 7.000 miloi parametrotik 70.000 milioira bitartean dituzte, eta ingeleseko LLama 2 ereduetatik eratorriak dira. Horretarako, LLama 2 gainean aurreikasketa jarraitua izeneko prozesua gauzatu da, 4.3 milioi dokumentu eta 4.200 milioi token duen euskarazko corpusa erabiliz. Euskararentzat kalitate handiko ebaluazio multzoen urritasunari aurre egiteko, lau ebaluazio multzo berri bildu ditugu: EusProficiency, EGA azterketaren atariko frogako 5.169 galdera biltzen dituena; EusReading, irakurketaren ulermeneko 352 galdera biltzen dituena; EusTrivia, 5 arlotako ezagutza orokorreko 1.715 galdera biltzen dituena; eta EusExams, oposizioetako 16.774 galdera biltzen dituena. Datu-multzo berri hauek erabiliz, Latxa eta beste euskarazko HEak ebaluatu ditugu (elebakar zein eleanitzak), eta esperimentuek erakusten dute Latxak aurreko eredu ireki guztiak gainditzen dituela. Halaber, GPT-4 Turbo HE komertzialarekiko emaitza konpetitiboak lortzen ditu Latxak, hizkuntza-ezagutzan eta ulermenean, testu-irakurmenean zein ezagutza intentsiboa eskatzen duten atazetan atzeratuta egon arren. Bai Latxa ereduen familia, baita gure corpus eta ebaluazio-datu berriak ere lizentzia irekien pean daude publiko https://github. com/hitz-zentroa/latxa helbidean.

Effective evaluation of language models remains an open challenge in NLP. Researchers and engineers face methodological issues such as the sensitivity of models to evaluation setup, difficulty of proper comparisons across methods, and the lack of reproducibility and transparency. In this paper we draw on three years of experience in evaluating large language models to provide guidance and lessons for researchers. First, we provide an overview of common challenges faced in language model evaluation. Second, we delineate best practices for addressing or lessening the impact of these challenges on research. Third, we present the Language Model Evaluation Harness (lm-eval): an open source library for independent, reproducible, and extensible evaluation of language models that seeks to address these issues. We describe the features of the library as well as case studies in which the library has been used to alleviate these methodological concerns.
