Call for participation: Shared task on Predicting Disagreements in WiC Annotations
by Dominik Schlechtweg 23 Sep '24

23 Sep '24

Dear colleagues, The CoMeDi (Context and Meaning—Navigating Disagreements in NLP Annotations) workshop will host a shared task. We invite participants to solve two subtasks given a pair of words uses: Subtask 1: Ordinal Word-in-Context Detection (OGWiC) Subtask 2: Disagreement in Word-in-Context Detection (DisWiC) The task takes a different view on modeling of word meaning by (i) treating WiC as an ordinal classification task, and (ii) making disagreement the explicit detection aim (instead of removing it). The workshop will colocated with COLING 2025, where the results of the shared task will be presented. All information can be found on our website: https://comedinlp.github.io/ Everyone is cordially invited to participate. Feel free to approach us in case of any questions. Best, Dominik -- https://garrafao.github.io/ https://www.ims.uni-stuttgart.de/en/institute/team/Schlechtweg/

by Stefania Degaetano-Ortlieb 16 Sep '24

16 Sep '24

Call for submissions: Conference on Rational Approaches in Language Science (RAILS) The 2nd Conference on Rational Approaches in Language Science (RAILS) will be held in Saarbruecken, Germany, 13-15 February 2025. The central theme of this conference is rational communication, i.e. the idea that language users continuously strive to optimize their means of communication to effectively convey their intended messages. RAILS brings together research on (1) how interlocutors process and update information in diverse situational contexts, (2) how language use is adapted to certain contexts and intended referents, and (3) how linguistic and conceptual information is stored and maintained in short- and long-term memory. We invite submissions from researchers across the language sciences – including speech science, theoretical linguistics, empirical linguistics, psycholinguistics and neuroscience, computational linguistics, as well as language development, change and evolution – who apply rational probabilistic explanations to linguistic phenomena, or bring novel experimental findings to bear on such accounts. Keynote speakers: Mark Dingemanse (Radboud University) Richard Futrell (University of California, Irvine) Adele Goldberg (Princeton University) Rachel Ryskin (University of California, Merced) Submission guidelines: Abstracts should be submitted as a single PDF file via https://app.oxfordabstracts.com/stages/43090/submissions/new <https://app.oxfordabstracts.com/stages/43090/submissions/new?behalf=false&f…>, adhering to the guidelines listed on our conference website <https://sfb1102.uni-saarland.de/sfb-conference-2025/>. We accept submissions for posters and/or talks. Talks are slated for 20 minutes plus 10 minutes for questions. Submission of planned work is invited for poster presentation only. Note that, if accepted, we expect results to be presented at the conference. Important dates: Submissions open: 8 July, 2024 Submissions due: 16 September, 2024 Notification of acceptance: 4 November, 2024 Registration period: 11 November-16 December, 2024 De-anonymized abstracts due in final form: 2 December, 2024 Conference: 13-15 February, 2025 Scientific Committee: Regine Bader Stefania Degaetano-Ortlieb Katja Haeuser Robin Lemke Ivan Yuen Scientific and financial support for this conference comes from the Collaborative Research Center SFB1102 Information Density and Linguistic Encoding <https://nam10.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.sfb110…>.

CFP: The 1st Workshop on NLP for Languages Using Arabic Script (AbjadNLP 2025)
by amalhaddad 30 Aug '24

30 Aug '24

CALL FOR PAPERS CALL FOR PAPERS: THE 1ST WORKSHOP ON NLP FOR LANGUAGES USING ARABIC SCRIPT (ABJADNLP 2025) https://wp.lancs.ac.uk/abjad/cfp/ Co-located with COLING 2025 Conference, Abu Dhabi, UAE (19-20 January 2025) Submission URL [1] AbjadNLP is dedicated to advancing innovation and gaining deeper insights into Natural Language Processing (NLP) for languages that use the Arabic script. Our primary focus is on Abjad and Ajami languages that utilise the Arabic script or its variations. Traditionally associated with Semitic languages, Abjad scripts represent consonants in every syllable. In contrast, Ajami scripts denote the alphabetic use of the Arabic script in various African contexts, representing non-Arabic languages. We are interested in research on languages that fall under the Abjad or Ajami categories that use the Arabic script or any variations of it. We invite contributions, discussions, and explorations that delve deep into the unique linguistic structures, resources, challenges, and untapped potential presented by Abjad and Ajami languages within the realm of NLP and language resources. Our goal is to create synergies among researchers by addressing the diverse phenomena and challenges inherent in these rich linguistic traditions. The workshop is proud to highlight our connections with the Masakhane NLP community and collaborations with institutions worldwide, such as COMSATS on Urdu, and the long-standing UCREL NLP Group at Lancaster University, whose work encompasses over 20 languages worldwide, including Abjad and Ajami languages. Note: We chose the name Abjad for simplicity, but our focus includes Abjad and other languages that have adopted the Arabic and Perso-Arabic scripts, as well as Ajami languages. We acknowledge that Sorani Kurdish, when written in Arabic script, follows an alphabet style rather than an Abjad style. TOPICS OF INTEREST: * Core Technologies: morphological analysis, disambiguation, tokenisation, POS tagging, named entity detection, chunking, parsing, semantic role labelling, sentiment analysis, language modelling, etc. * Applications: machine translation, speech recognition, speech synthesis, optical character recognition, assistive technologies, social media, etc. * Resources and Tools: dictionaries, annotated data, corpora, orthography descriptions, font technology, glyph rendering, text input methodologies, spell-checking, speech-to-text solutions, BLARK descriptions, open access corpora. * Cultural and Sociolinguistic Considerations: text processing, transliteration challenges, and solutions, cultural contexts in NLP applications. SUBMISSION GUIDELINES: We follow the COLING 2025 standards for submission format and guidelines. Submissions should conform to the following types: * Long papers: Up to eight (8) pages, presenting substantial, original, completed, and unpublished work. * Short papers: Up to four (4) pages, describing a small focused contribution, negative results, system demonstrations, etc. KEY DATES: * 1st Call for Papers Announcement: 16 July 2024 * 2nd Call for Papers Announcement: 16 August 2024 * Paper Submission Deadline: 15 November 2024 * Notification of Paper Acceptance: 6 December 2024 * Camera-ready Paper Deadline: 13 December 2024 * Workshop Date: 19 or 20 January 2025 ORGANISING COMMITTEE: General Chair: Mo El-Haj, Lancaster University Programme Chairs: * Hugh Paterson III, Collaborative Scholar * Saad Ezzini, Lancaster University * Ignatius Ezeani, Lancaster University Review Committee: * Mahum Hayat Khan, University of La Rioja * Muhammad Sharjeel, COMSATS University Islamabad Publication Chair: Sina Ahmadi, University of Zurich Publicity Chairs: * Cynthia Amol, Maseno University * Amal Haddad Haddad, University of Granada * Jaleh Delfani, University of Surrey Advisory Committee: * Ruslan Mitkov, Lancaster University * Paul Rayson, Lancaster University Links: ------ [1] https://softconf.com/coling2025/AbjadNLP25/

Hi all, In the age of decoder-only LLMs, I'll like to ask if there's any competitive encoder-decoder architectures that are known to scale well for multilingual seq2seq tasks? - https://huggingface.co/docs/transformers/en/model_doc/mt5 - https://huggingface.co/facebook/m2m100_418M - https://huggingface.co/google-bert/bert-base-multilingual-cased + https://www.kaggle.com/code/alvations/neural-plasticity-bert2bert-on-wmt14 - https://huggingface.co/Helsinki-NLP/opus-mt-en-mul + https://huggingface.co/Helsinki-NLP/opus-mt-mul-en - https://huggingface.co/docs/transformers/en/model_doc/umt5 There's these that reported state-of-the-art NLI scores but they were not known to be multilingual - https://huggingface.co/google/ul2 - https://huggingface.co/docs/transformers/en/model_doc/flan-t5 - https://huggingface.co/docs/transformers/en/model_doc/byt5 There's some ideas on doing encoder with mamba https://github.com/state-spaces/mamba/issues/78 but it looks like an open question. Other than the above, are there any competitive encoder-decoder architectures that are known to scale well for multilingual seq2seq tasks? Thank you in advance for the pointers! Regards, Liling

corpora of technologies? ...
by Albretch Mueller 29 Aug '24

29 Aug '24

In the main, the Greek word "philology" has been taken as meaning "bibliosophy". I argue, it shouldn't mainly or just be about books. I have tried unsuccessful searches on: "corpora research" "technologies"; "corpora research" "patents"; ... to have search engines make sense of it in their own ways, not as meaning a corpus of technologies as such. Lewis Mumford in his worthwhile "Technics and Civilization" considers the first "eotechnic" phase of technologically civilized life approximately from AD 1000 AD 1800, a time frame during which the mechanical clock took relevance as a coordinating device. Yet, since around 600 BC Ancient Ionian/Greek philosophers had been pondering about techne and its relationship to concrete engineering and social technologies, including its intersubjective and moral aspects. Solon wondered about the relationship between techne and virtue and Plato dedicated in explicit and inferred way most of his dialogues to that theme. Mumford also pointed out that there have always been the kind of scientists and engineers such as Archimedes, Galileo, Agricola, Euler and Franz Reuleaux; who saw their business in "techne-like" ways. Basically, they take simple physical devices such as the lever, the wheel and the pulley (already more of a mechanism), to which the pressure gradient force in air naturally making windmills move and electromagnetic forces both as they happen in fields and on a quantum mechanical level on diodes, transistors and LEDs should be also included. Those most simple processes are seen as kinds of characters of an alphabet out of which mechanisms: "words" and "lexical bundles" of sort are contrived to create machines in a through and through "textual" way by chaining "kinematic pairs" in a way that at each juncture physical conservation laws apply. Cross correlating the pieces of such technological texts in a DAG kind of way you naturally build a corpus. So, as ancient philosophers intuited long ago the whole of society is a corpus. Do you know of any prior art relating to such corpora research? Please, if you do could you point me to such resources in a way that I can access them? I am what they call an independent researcher and it is virtually impossible for me to work. lbrtchx: corpora of technologies? ...

ACM Transactions on Recommender Systems CFP: RecSys 4 Good
by antonela.tommasel＠isistan.unicen.edu.ar 28 Aug '24

28 Aug '24

CALL FOR PAPERS: ACM Transactions on Recommender Systems Special Issue on Recommender Systems for Good Submission deadline: 24. December 2024 Guest Editors: - Marko Tkalčič, University of Primorska, Slovenia - Noemi Mauro, University of Turin, Italy - Alan Said, University of Gothenburg, Sweden - Nava Tintarev, University of Maastricht, Netherlands - Antonela Tommasel, ISISTAN, CONICET-UNCPBA, Argentina Recommender systems are among the most widely used applications of machine learning. Since they are so widely used, it is important that we, as practitioners and researchers, think about the impact these systems may have on users, society, and other stakeholders. In practice, the focus is often on systems and values of improving key performance indicators (KPIs), such as increased sales or customer retention. Recommendation technology is currently underutilized to serve societal goals that go beyond the business objectives of individual corporations. However, other values, bound more to societal good, could be considered in the development and goals of a recommender system. In fact, recommender systems have already been explored to stimulate healthier eating behavior and for improved health and well-being in general, to help low-income families make school choices, to suggest successful learning paths for students, to entice climate-protecting energy-saving behavior, to support fair micro-lending, or improve the information diets of news readers. Research in these areas is however limited in numbers, compared to the many papers that are published every year that propose new models for improved movie recommendations. Moreover, concerning the methodology and evaluation perspective in this area, it is essential to find a clear methodology and criteria for evaluating the effectiveness and "goodness" of the proposed algorithms. This includes acknowledging that different values may be conflicting, as well as resolving how and when (and by whom) certain values should be prioritized over others such as in the NORMalize workshop (https://sites.google.com/view/normalizeworkshop). Research on "Recommender Systems for Good" may benefit from an interdisciplinary approach, drawing on insights from fields such as computer science, ethics, sociology, psychology, law, and economics. Collaborations with stakeholders from diverse backgrounds can enrich the research and ensure that recommendations are grounded in real-world needs and values. This special issue aims to present state-of-the-art research works where recommender systems have a positive societal impact and help us address urgent societal challenges. It will thereby serve as a call to action for more research in these areas. Ultimately, through this special issue, we hope to establish a vision of "Recommender Systems for Good', following the spirit of the "AI for Good" initiative (https://aiforgood.itu.int) to achieve the United Nations Sustainable Development Goals (2015) and the more recent UNESCO recommendation on the Ethics of Artificial Intelligence (2024) (https://www.unesco.org/en/artificial-intelligence/recommendation-ethics). Topics: We aim to collect the latest research on recommender systems for societal good. The topics of the special issues include (but are not limited to): - Recommender systems for safety, security, and privacy (e.g., reducing poverty and inequality) - Recommender systems that protect the environment and ecosystems (e.g., lower energy consumption, water and energy management) - Recommender systems that give control of data back to the users (e.g., transparency of data, models, and outputs) - Recommender systems for the interconnected society (e.g., increase of solidarity, online conversational health, multi-stakeholder recommenders) - Accountability in recommender systems, including addressing emerging regulations, such as the DSA (Digital Service Act) - Recommender systems for the public good (e.g., mental and physical health, welfare, digital literacy, stakeholder engagement, e-learning) - Introspective studies on the current state of RSs concerning societal good - Fairness-preserving and fairness-enhancing recommender systems, unbiased recommendations (e.g. to preserve gender equality) - Responsible recommendation (e.g., in social media and traditional news, avoiding filter bubbles and echo chambers) - Sustainability and Cultural recommendations (e.g., art, cultural heritage) - Recommendations to support disadvantaged groups (e.g., elderly, minorities) - Recommender systems for personal development and well-being (e.g., behavioral change, fitness, self-actualization, personal growth) Important Dates: - Submission deadline: December 24, 2024 - First-round review decisions: March 24, 2025 - Deadline for revision submissions: May 24, 2025 - Notification of final decisions: June 24, 2025 Submissions that are received before the first deadline will be directly sent out for review; papers will be immediately published online after acceptance. Submission Information: The special issue welcomes technical research papers, survey papers, and opinion/reflective papers. Each paper should address one or more of the abovementioned topics or be in other scopes of Recommender Systems for Good. The special issue will also consider peer-reviewed journal versions (at least 30% new content) of top papers from related recommender system conferences such as RecSys, SIGIR, KDD, CIKM, IUI, UMAP, CHI, WSDM, ACL, etc. Prospective authors may take advantage of submitting an early version of their work to the ACM RecSys RecSoGood Workshop https://recsogood.github.io/recsogood24/. The new content must be in terms of intellectual contributions, technical experiments, and findings. Submissions must be prepared according to the TORS submission guidelines (https://dl.acm.org/journal/tors/author-guidelines) and must be submitted via Manuscript Central (https://mc.manuscriptcentral.com/tors). For questions and further information, please contact the guest editors at rs4good [at] acm [dot] org.
