7th Call for Papers – LaTeLL 2026 (Low-Resource Languages)
by ernesto.estevanell＠ua.es 08 Apr '26

08 Apr '26

International Conference 'LAnguage TEchnologies for Low-resource Languages' (LaTeLL '2026) Fes, Morocco 30 September, 1 and 2 October 2026 www.latell.org/2026/ [1] 7th Call for Papers The conference Natural Language Processing (NLP) has witnessed remarkable progress in recent years, largely driven by the emergence of deep learning architectures and, more recently, large language models (LLMs). Nevertheless, these advances have disproportionately benefited high-resource languages that possess abundant data for model training. By contrast, low-resource languages which account for at least 85% of the world's linguistic diversity and are often spoken by smaller or marginalised communities, have not yet reaped the full benefits of contemporary NLP technologies. This imbalance can be attributed to several interrelated factors, including the scarcity of high-quality training data, limited computational and financial resources, and insufficient community engagement in data collection and model development. Developing NLP applications for low-resource languages poses major challenges, particularly the need for large, well-annotated datasets, standardised tools, and robust linguistic resources. Although several workshops have previously addressed NLP for low-resource languages, _LaTeLL_ represents the first international conference dedicated specifically to the automatic processing of such languages. The event aims to provide a forum for researchers to present and discuss their latest work in NLP in general, and in the development and evaluation of language models for low-resource languages in particular. Conference topics We invite submissions on a broad range of themes concerning linguistic and computational studies focusing on low-resource languages, including but not limited to the following topics: Language resources for low-resource languages * Dataset creation and annotation * Evaluation methodologies and benchmarks for low-resource settings * Lexical resources, corpora, and linguistic databases * Crowdsourcing and community-driven data collection * Tools and frameworks for low-resource language processing Core language technologies for low-resource languages * Language modelling and pre-training for low-resource languages * Speech recognition, text-to-speech, and spoken language understanding * Phonology, morphology, word segmentation, and tokenisation * Syntax: tagging, chunking, and parsing * Semantics: lexical and sentence-level representation NLP Applications for low-resource languages * Information extraction and named entity recognition * Question answering systems * Dialogue and interactive systems * Summarisation * Machine translation * Sentiment analysis, stylistic analysis, and argument mining * Content moderation * Information retrieval and text mining Multimodality and Grounding for low-resource languages * Vision and language for low-resource contexts * Speech and text multimodal systems * Low-resource sign language processing Ethics, Equity, and Social Impact for low-resource languages * Bias and fairness in low-resource language technologies * Sociolinguistic considerations in technology development * Cultural appropriateness and sensitivity Human-Centred Approaches in low-resource languages * Usability and accessibility of low-resource language technologies * Educational applications and language learning * Community needs assessment and technology adoption * User experience research in low-resource contexts Multilinguality and Cross-Lingual Methods for low-resource languages * Multilingual language models and their adaptation * Code-switching and code-mixing * Cross-lingual transfer learning in low-resource languages. Special Theme Track 1 -- Building Applications Based on Large Language Models for Low-Resource Languages _LaTeLL'2026_ will feature a Special Theme Track dedicated to the development of applications based on Large Language Models (LLMs) for low-resource languages. This track aims to explore innovative methodologies, architectures, and tools that leverage the power of LLMs to enhance linguistic processing, accessibility, and inclusivity for underrepresented languages. Contributions are encouraged on topics such as model adaptation and fine-tuning, multilingual and cross-lingual transfer, ethical and fairness considerations, and the creation of datasets and benchmarks that facilitate the integration of LLM-based solutions in low-resource settings. Special Theme Track 2 -- Modern Standard Arabic (MSA) and Arabic Dialects This special track addresses the unique challenges and opportunities in processing Modern Standard Arabic (MSA) and the rich landscape of Arabic dialects. The diglossic nature of Arabic, where the formal MSA coexists with numerous, widely used spoken dialects, presents a significant hurdle for NLP. While MSA is relatively well-resourced, Arabic dialects are quintessential examples of low-resource languages, often lacking standardised orthographies, annotated corpora, and dedicated processing tools. This track invites submissions on novel research and resources aimed at bridging this gap and advancing the state of the art in Arabic language technology. Topics of interest include, but are not limited to: * Dialect identification and classification * Creation of corpora and lexical resources for Arabic dialects * Machine translation between MSA and dialects, and across different dialects * Speech recognition and synthesis for dialectal Arabic * Computational modelling of morphology, syntax, and semantics for dialects * NLP applications (e.g., sentiment analysis, NER) for dialectal user-generated content * Code-switching between Arabic dialects, MSA, and other languages Submissions and Publication _LaTeLL'2026_ welcomes high-quality submissions in English, which may take one of the following two forms: * Regular (long) papers: Up to eight (8) pages in length, presenting substantial, original, completed, and unpublished research. * Short (poster) papers: Up to four (4) pages in length, suitable for concise or focused contributions, ongoing research, negative results, system demonstrations, and similar work. Short papers will be presented during a dedicated poster session. The conference will not consider submissions consisting of abstracts only. All accepted papers (both long and short) will be published as electronic proceedings (with ISBN) and made available on the conference website at the time of the event. The organisers intend to submit the proceedings for inclusion in the ACL Anthology. To prepare your submission, please make sure to use the LaTeLL'2026 style files available here: LaTeX: https://drive.google.com/file/d/1RceWyUqjFLEbv_oNto-x2Quop7qT4-wf/view?usp=… [2] Word: https://docs.google.com/document/d/1m6VeC9jtMpe-Ku2QREgrPlE2-NTDvJvZ/edit?u… [3] Overleaf: https://www.overleaf.com/read/ttzzfcnjrgvw#e82bef [4] Papers should be submitted through Softconf/START using the following link: https://softconf.com/p/latell2026 Authors of papers receiving exceptionally positive reviews will be invited to prepare extended and substantially revised versions for submission to a leading journal in the field of Natural Language Processing (NLP).

CfP: RiCL Journal special issue - Learner Corpus Research meets the Common European Framework of Reference for Languages and the Companion Volume
by María Belén Díez Bedmar 08 Apr '26

08 Apr '26

*CFPs special issue of Research in Corpus Linguistics (RiCL)* *‘Learner Corpus Research meets the Common European Framework of Reference for Languages and the Companion Volume’* Due to the importance of the *Common European Framework of Reference for Languages* (CEFR) and the *Companion Volume* (CV) (Council of Europe, 2001, 2020) for the learning, teaching and assessment of languages, most learner corpora nowadays employ the learner’s CEFR level to specify the student’s communicative language competence level or proficiency level. Most learner corpora compiled in CEFR-aligned high-stakes foreign language accreditation/certification exams - for instance, the *Cambridge Learner Corpus* (O’Keeffe & Mark, 2017), the *FineDesc Learner Corpus *(Díez-Bedmar, 2025) - are composed of learners of English production in successful certification/accreditation exams at different CEFR levels. Other target languages are compiled in similar foreign language accreditation/certification exam conditions, such as the CELI corpus for Italian (Spina et al., 2023) or the Merlin corpus for Italian, German and Czech (Wisniewski, 2020). Other learner corpora composed of accreditation/certification exams that are not aligned to the CEFR or learner corpora compiled in other contexts have also been partially or fully aligned to the CEFR levels, as reported by Gablasova et al., (2019) regarding the *Trinity Lancaster* *Corpus*, Thewissen (2013) concerning *ICLE* or Tono (2018) as to the *JEFLL corpus*. The use of LCR results from CEFR-aligned learner corpora to inform or facilitate the implementation of the CEFR/CV is, however, still limited. Among the most important LCR contributions in this respect are those by the *English Profile Project* (Salamoura, 2008) and the CEFR-J Project (Tono, 2019). The former used the *Cambridge Learner Corpus* to provide linguistic information on the language produced at each CEFR level (UCLES/CUP, 2011) and freely available online resources (eg., the English Grammar Profile and the English Vocabulary Profile). The latter employed learner corpora, among other corpora types, to adapt the CEFR for the L1 Japanese EFL context (12 sublevels), create the Vocabulary Profile and the Grammar Profile. Despite these efforts, CEFR/CV end-users and stake-holders find difficulties in the implementation of the CEFR/CV in their L1-contexts, on most occasions due to the language neutral nature of the CEFR/CV descriptors (see Díez-Bedmar & Byram, 2019; Díez-Bedmar & Luque-Agulló, 2023; Luque-Agulló & Díez-Bedmar, 2025). It is for this reason that they demand fine-tuned descriptors, i.e., CEFR/CV descriptors informed by CEFR-aligned L1-specific learner corpus results (Díez-Bedmar, 2018). In the Spanish context, the *FineDesc Project* (Grant PID2020-117041GA-I00, funded by MICIU/AEI/10.13039/501100011033) has provided L1 Spanish CEFR/CV end-users and stake-holders’ with fine-tuned descriptors thanks to the analysis of the 1.3-million-word *FineDesc Learner* *Corpus* (Díez-Bedmar, 2025), a freely available L1-specific learner corpus by L1 Spanish monolingual students (or bilingual L1 Spanish/a co-official language in Spain). The learner corpus results have informed fine-tuned descriptors not only for the linguistic competence, but also for the sociolinguistic and pragmatic ones, when students engage in different communicative language activities at B1, B2 and C1 levels (see Díez-Bedmar et al., 2026). These fine-tuned descriptors aim at paving the way for the implementation of the CEFR/CV in the L1 Spanish context. These are just some examples which show how LCR may inform the CEFR/CV and facilitate its implementation in different contexts. Other efforts are being made by the LCR community by using either general CEFR-aligned learner corpora or L1-specific ones, as shown in some papers presented at the International Online Conference ‘Bringing together research on the CEFR/CV and LCR: a focus on descriptors’ which was organized by the FineDesc Project (https://web.ujaen.es/investiga/finedesc/index.php). It is the objective of this special issue to bring together research on the different ways how LCR may meet the CEFR/CV. Contributions which employ any reliably CEFR-aligned learner corpus with this objective in mind are welcome, whether they were presented at the conference or not. Researchers who do not have access to any CEFR-aligned learner corpus are encouraged to use the *FineDesc Learner Corpus*, freely available at www.finedesc.com. *Potential topics for this special issue are (but are not limited to):* -The fine-tuning of CEFR/CV descriptors for L1-specific contexts thanks to LCR. -The integration of CAF results in fine-tuned descriptors. -The (cross-sectional) analysis of CEFR-aligned learner corpora considering the linguistic, sociolinguistic or pragmatic competences to inform CEFR-aligned pedagogical resources/language assessment. -The exploitation of CEFR-aligned learner corpora to design tools/software which may help analyse learner corpora at different CEFR levels. -The overcoming of any difficulties in CEFR/CV implementation with the help of LCR. *Important dates* Deadline for proposals: April 30, 2026 Outcome of proposal review: May 21, 2026 Deadline for manuscript first drafts: December 1,2026 Notification of reviewer outcome: March 5, 2027 Deadline for manuscript final drafts: May 28th, 2027 Special issue publication: Autumn 2027 *Proposal format and submission* Potential contributors should prepare an extended 800-word abstract of the proposed paper following RiCL’s submission guidelines, which can be found at https://ricl.aelinco.es/index.php/ricl/about/submissions The abstract should include a tentative title, motivate the study, state the research questions, provide methodological information (learner corpus or learner corpora analysed and the procedure employed to align it/them to CEFR/CV levels as well as the statistical tests employed), tentative results and clear information on the way how the results inform the CEFR/CV and its implementation. Please submit your proposal to the special issue editor, María Belén Díez-Bedmar (belendb(a)ujaen.es), before the deadline (April 30, 2026) including in your proposal your name(s), email(s) and affiliation(s). *Peer review* All accepted manuscripts will undergo double-blind peer review. *References* Council of Europe (2001).

Theoretical, Empirical, and Applied Perspectives"). The project is led by co-PIs Prof. Dr. Tatjana Scheffler (Ruhr-Universität Bochum, Germany) and Prof. Dr. Patrick Grosz (University of Oslo, Norway). The project plans to investigate emojis from a formal semantics perspective informed by experimental data. Our research primarily concentrates on the semantics of face emojis, and builds on the hypothesis that face emojis have partly conventionalized (symbolic) meaning, but also incorporate iconic meaning due to their resemblance to human faces, which they are meant to depict. We aim to delineate the formal semantic denotation of face emojis, and whether it can be decomposed into smaller meaning components. Second, we aim to empirically establish the semantic type of expressive face emojis, i.e., whether or not they serve as functions, taking a propositional argument that they comment on. Your tasks: - Independent research on the semantics and pragmatics of emojis in the reseearch project "Decompositional Semantics of Face Emojis in Digital Communication (EmDiCom 2)". - Participation in the interdisciplinary DFG priority program "Visual Communication" (e.g., participation in network meetings and short-term collaborations) - Planning and conducting linguistic online experiments (acceptability studies, reading time measurements) - Collaboration on publications and presentations at international conferences - Supervision of research assistants - Organization of scientific events (workshops) Your profile: - An above-average linguistics PhD is required - Background in theoretical linguistics, preferably formal semantics/pragmatics - Demonstrated experience in experimental linguistics and statistical methods - Knowledge of tools for creating and conducting online experiments is an advantage - Interest in visual communication (e.g., gestures, facial expressions, emojis, Sign Language) - Excellent English skills We offer: - Challenging and varied tasks with a high degree of personal responsibility - Exciting research on a current topic - International cooperation with the "Super Linguistics" group at the University of Oslo and within the "Visual Communication" DFG priority program - A friendly and enthusiastic team at the interface of formal, digital, and computational linguistics - The opportunity to join one of the largest universities in Germany, part of the University Alliance Ruhr - Professional development, mentoring, and training Further information: The position is salaried and based on the collective agreement of the Länder (TV-L).
