2nd LLMs4Subjects Shared Task: https://sites.google.com/view/llms4subjects-germeval/
KONVENS 2025: https://konvens-2025.hs-hannover.de/about/
Task Overview
LLMs4Subjects challenges the research community to develop cutting-edge LLM-based solutions for subject tagging of technical records from Leibniz University's Technical Library (TIBKAT). Participants are tasked with leveraging large language models (LLMs) to tag technical records using the GND taxonomy. The task involves bilingual language modeling, as systems must process technical documents in both German and English. Successful solutions may be integrated into the operational workflows of TIB, the Leibniz Information Centre for Science and Technology.
With the rapid advancements in LLMs, the focus is shifting toward making these models more energy- and compute-efficient while maintaining high performance. Recent innovations, such as the DeepSeek series, have demonstrated how techniques like mixture-of-experts (MoE) and model distillation can significantly reduce computational costs without sacrificing effectiveness.
The 2nd LLMs4Subjects shared task highlights the importance of efficiency in LLMs, encouraging participants to explore strategies that enhance model performance while optimizing for energy consumption and inference speed. We welcome approaches (but not limited to) that leverage model compression, quantization, efficient fine-tuning, and adaptive computation techniques to push the boundaries of sustainable AI development.

ClimateCheck: Shared Task on Scientific Fact-Checking of Social Media Claims on Climate Change
Hosted as part of the SDP 2025 Workshop at ACL 2025
31 July 2025
Vienna, Austria
ClimateCheck Shared Task: https://sdproc.org/2025/climatecheck.html
Competition on Codabench: https://www.codabench.org/competitions/6639/
Shared Task Overview
Social media facilitates discussions on critical issues such as climate change, but it also contributes to the rapid dissemination of misinformation, which complicates efforts to maintain an informed public and create evidence-based policies. In this shared task, we emphasise the need to link public discourse to peer-reviewed scholarly articles by gathering claims from social media about climate change (both real-life and automatically generated ones) as well as a corpus of about 400,000 abstracts of publications from climate science research. The participants will be asked to retrieve relevant abstracts for each claim (subtask I) and classify the relation between the claim and abstract as ‘supports’, ‘refutes’, or ‘not enough information’ (subtask II). Participants are allowed to take part either in subtask I only, or in both subtasks.
Subtask I: Abstracts Retrieval
Task: given a claim from social media about climate change and a corpus of abstracts, retrieve the top 10 most relevant abstracts.
Evaluation: Recall@K (K=2, 5, 10) and B-Pref based on annotated gold data; additional unjudged documents will be reviewed by annotators.
Subtask II: Claim Verification
Task: given the claim-abstract pairs received from the previous subtask, classify their relation as ‘supports’, ‘refutes’, or ‘not enough information’.
Evaluation: Precision, Recall, and F1 weighted scores based on annotated documents.
Important dates
Release of training data: April 1, 2025
Release of testing data: April 15, 2025
Deadline for system submissions: May 16, 2025

SciVQA: Scientific Visual Question Answering Shared Task
Hosted as part of the SDP 2025 Workshop at ACL 2025
31 July 2025
Vienna, Austria
SciVQA Shared Task: https://sdproc.org/2025/scivqa.html
Competition on Codabench: https://www.codabench.org/competitions/5904
Shared Task Overview
Scholarly articles convey valuable information not only through unstructured text but also via (semi-)structured figures such as charts and diagrams. Automatically interpreting the semantics of knowledge encoded in these figures can be beneficial for downstream tasks such as question answering (QA). In SciVQA, challenge participants will develop multimodal QA systems using a dataset of 3000 images of scientific figures from ACL Anthology and arXiv papers. Each figure is annotated with seven QA pairs (21000 in total) and includes metadata such as caption, ID, type (e.g., compound, line graph, bar chart, scatter plot), and QA pair type. This shared task specifically focuses on closed-ended visual (i.e., addressing visual attributes such as colour, shape, size, height, etc.) and non-visual (not addressing figure visual attributes) questions.
Evaluation
Systems will be evaluated using BERTscore, ROUGE-L, and ROUGE-1 metrics. Automated evaluations of submitted systems will be performed through Codabench.
Important Dates
Release of training data: April 1, 2025

We are pleased to announce the *GermEval Shared Task on Candy Speech
Detection („Flausch-Erkennung“)*
This is the third call to participate in the shared task on candy speech
detection („Flausch-Erkennung“).
We invite everyone from academia and industry to participate in the
shared task.
The workshop discussing the results of this shared task is planned to be
held in conjunction with the Conference on Natural Language Processing
(KONVENS) in September 2025.
*Introduction*
Numerous methods have been developed for detecting and censoring
negative speech (e.g., hate speech or offensive or harmful language) on
social media platforms. However, there is much less focus on identifying
and promoting positive supportive discourse in online communities. Our
shared task aims to address this gap and encourage researchers to focus
on such positive expressions.
The task is to identify expressions of candy speech (Flausch) in online
posts (YouTube comments). We define candy speech as expression of
positive attitudes on social media toward individuals or their output
(videos, comments, etc.). The purpose of candy speech is to encourage,
cheer up, support and empower others. It can be viewed as the
counterpart to hate speech, as it also aims to influence the self-image
of the target person or group, but in a positive way.
*Data*
We will provide the participants with annotated training (and
development) and unlabeled test datasets containing complete written,
German language comment threads under YouTube videos posted by different
content creators. The content creators and communities vary in topic,
style, age group, etc. The training and test datasets do not overlap in
terms of YouTube videos. Furthermore, the test dataset mostly contains
(comments on) videos from content creators that are different from those
in the training dataset. The communities commenting on these videos can
therefore be expected to differ.
*Task Details*
Candy speech detection is the task of identifying the presence of candy
speech (at the span level) in a given YouTube comment and classifying
each expression in one of the predefined categories. This shared task
focuses on German speaking YouTube communities. Participants will be
provided with a dataset of YouTube comments manually annotated for
different types of candy speech expressions.
We offer the following two subtasks. Participants in this year's shared
task may choose to participate in either subtask:
Subtask 1: Coarse-Grained Classification
The goal of this subtask is to identify whether the given comment
contains candy speech ("Flausch") or not. The dataset is manually
annotated for the presence of candy speech.
Subtask 2: Fine-Grained Classification
The goal of this subtask is to identify the span of each candy speech
expression in a given text and classify it in one of the predefined
categories. The dataset is manually annotated for 10 different types of
candy speech expressions, such as “positive feedback”, “compliment”,
“group membership” etc.
More details on the subtasks (including examples) can be found at the
website of the shared task (see link below).

== Second Call for Papers and Extended Abstracts ==
1st Workshop on Automatic Assessment of Atypical Speech (AAAS-2025)
We would like to invite you to submit papers to AAAS workshop co-located with NoDaLiDa/Baltic-HLT<https://www.nodalida-bhlt2025.eu> in Hestia Hotel Europa in Tallinn, Estonia on March 5th, 2025.
Workshop website: https://teflon.aalto.fi/aaas-2025/
== Important Dates ==
Submission DL: 16 December 2024 (both papers and abstracts)
Notification of acceptance: 24 January 2025
Camera-ready DL: 3 February 2025
Workshop: 5 March 2025 (full day)
All deadlines are 11:55PM UTC-12:00 ("anywhere on Earth").
== Overview ==
Automatic Assessment of Atypical Speech (AAAS) explores the assessment of pronunciation and speaking skills of children, language learners, people with speech sound disorders and methods to provide automatic rating and feedback using automatic speech recognition (ASR) and large language models (LLMs). Automatic speaking assessment (ASA) is a rapidly growing field that answers to the need of developing AI tools for self-practising second and foreign language skills. This is not limited to pronunciation assessment, but the AI tools can also provide more complex feedback about fluency, vocabulary and grammar of the recorded speech. ASA is also very relevant for detection and quantification of speech disorders and for developing speech exercises that can be performed independent of time and place. The important applications of non-standard speech also include interfaces for children and elderly speakers as an alternative to using text input and output. The topic is timely, because the latest large speech models allow us now to develop ASR and classification methods for low-resourced data, such as atypical speech, where annotated training datasets are rarely available and expensive and difficult to produce and share. The goal of this workshop is to present the latest results in ASA and discuss the future work and collaboration between the researchers in Nordic and Baltic countries.
== Topics of Interest ==
In particular, we would like to invite students, researchers, and other experts and stakeholders to contribute papers and/or join the discussion on the following (and related) topics:
Automatic speaking assessment (ASA) for L2 (second or foreign language) pronunciation
ASA for spoken L2 proficiency
ASA for speech sound disorders (SSD)
Automatic speech recognition (ASR) for L2 learners
ASR for children and young L2 learners
ASA and ASR for Nordic and other low-resource languages and tasks
Spoken L2 learning and speech therapy using games
Automatic generation of verbal feedback for spoken L2 learners using LLMs
== Submission Details ==
We accept both short and long papers, as well as demo papers. The submissions must describe original and unpublished work.
Paper length:
Short and demo papers up to 4 pages.
Long papers up to 8 pages.
References are not included in the page count, and the camera-ready versions of accepted papers will be added to the page to address reviewer comments.
Papers should describe original unpublished work or work-in-progress and will be peer-reviewed by at least two members of the program committee in a double-blind fashion. All accepted papers will be collected into a proceedings volume to be published in the ACL anthology. All submissions must follow the NoDaLida template, available in both LaTeX and MS Word. The links to the templates can be found here:
https://drive.google.com/file/d/1osWGzuRnYRQGRS70Lx_pdQKrIT-NefKS/viewhttps://www.overleaf.com/latex/templates/instructions-for-nodalida-baltic-h…
The submission will be through EasyChair:
https://easychair.org/conferences/?conf=aaas2025
We also invite submissions of maximum 2-page long extended non-anonymous abstracts with any number of pages for references describing work in progress, negative results and opinion pieces. The abstracts, which should follow the same formatting templates as the peer-reviewed papers, will be considered for presentation by the workshop organisers and the accepted ones will be posted on the workshop website. The abstracts can be based on results related to our theme and already published elsewhere. The abstracts will not be published in the proceedings, but only in the workshop program.
Please also consider volunteering to review 2-3 papers.
== Invited Speakers ==
We have the pleasure to announce two invited speakers:
1. Nina R. Benway: What is so hard about AI Speech Therapy? Evidence from Efficacy Trials.
Nina R Benway, PhD CCC-SLP, is a Postdoctoral Fellow in Electrical and Computer Engineering with Dr. Carol Espy-Wilson. Nina completed her doctoral training in speech-language pathology (concentration: neuroscience) with Dr. Jonathan Preston at Syracuse University, focusing on clinical trials in children with chronic rhotic speech sound disorders. The three studies of her dissertation resulted in the curation of an open-access 175,000-utterance speech corpus, the engineering of audio classification algorithms predicting speech-language pathologist perception of rhotic speech errors, and the clinical trial validation of an artificial intelligence tool that fully automates a speech sound treatment session. Nina’s doctoral training builds upon her undergraduate training in linguistics (acoustic phonetics) at Cornell University, graduate clinical training at The College of Saint Rose, and six years of clinical practice. Through these experiences Nina has refined a multidisciplinary skill set in speech science, speech signal processing, natural language processing, corpus phonetics, machine learning/artificial intelligence (AI), user interface development, cognitive frameworks of learning, and neurocomputational frameworks of speech production.
2. Ari Huhta: Automatic assessment of second/foreign language speaking: Review of developments for examination and teaching/learning purposes.
Ari Huhta is a Professor of Language Assessment at the Centre for Applied Language Studies, University of Jyväskylä, Finland. His research interests include diagnostic foreign/second language (L2) assessment, computerised assessment, self-assessment, as well as the development of reading, writing and vocabulary knowledge in L2. He was involved in developing the large-scale multilingual DIALANG online assessment and feedback system in the early 2000s and since then he has specialised in assessments that support language learning. Although his research has focused on learning and assessing reading and writing, he has been involved in designing several rating scales for speaking and in evaluating rating quality and studying rater behavior. Recently, he has participated in research projects that are developing ASR and automated assessment of L2 speaking, as well as using LLMs to evaluate Finnish L2 learners’ proficiency level.
