Call for participation - Arabic NER Shared Task 2023
by naghamghanim＠gmail.com 24 Mar '23

24 Mar '23

---------------------------------------------- Invitation to Arabic NER Shared Task 2023 ---------------------------------------------- Dear colleagues, We are happy to invite you to join the Arabic NER SharedTask 2023 which will be organized as part of the WANLP 2023. We will provide you with a large corpus and Google Colab notebooks to help you reproduce the baseline results. دعوة للمشاركة في مسابقة استخراج الكيونات المسماه من النصوص العربية. سنزود المشاركين بمدونة وبرمجيات للحصول على نتائج مرجعية يمكنهم البناء عليها. For more details please visit the shared task website from ( https://dlnlp.ai/st/wojood/ ). You can register directly from ( https://docs.google.com/forms/d/e/1FAIpQLSeWwvGSRMcSa7CHStGLkE8ODY87571wGD2… ). ----------------------------------------- INTRODUCTION ----------------------------------------- Named Entity Recognition (NER) is integral to many NLP applications. It is the task of identifying named entity mentions in unstructured text and classifying them to predefined classes such as person, organization, location, or date. Due to the scarcity of Arabic resources, most of the research on Arabic NER focuses on flat entities and addresses a limited number of entity types (person, organization, and location). The goal of this shared task is to alleviate this bottleneck by providing Wojood, a large and rich Arabic NER corpus. Wojood consists of about 550K tokens (MSA and dialect, in multiple domains) that are manually annotated with 21 entity types. ----------------------------------------- REGISTRATION ----------------------------------------- Participants need to register via this form (https://forms.gle/UCCrVNZ2LaPviCZS6). Participating teams will be provided with common training development datasets. No external manually labelled datasets are allowed. Blind test data set will be used to evaluate the output of the participating teams. Each team is allowed a maximum of 3 submissions. All teams are required to report on the development and test sets (after results are announced) in their write-ups. ----------------------------------------- FAQ ----------------------------------------- For any questions related to this task, please check our Frequently Asked Questions (https://docs.google.com/document/d/1XE2n89mFLic2P9DO_sAD51vy734BOt0kgtZ6bFf…) ----------------------------------------- IMPORTANT DATES ----------------------------------------- Below is subject to change: - March 03, 2023: Registration available - March 25, 2023: Data-sharing and evaluation on development set Avaliable - April 10, 2023: Registration deadline - May 20, 2023: Test set made available - May 30, 2023: Evaluation on test set (TEST) deadline - Jun 25, 2023: Shared task system paper submissions due - JUL 15, 2023: Notification of acceptance - Jul 30, 2023: Camera-ready version - TBA, 2023: WANLP 2023 Conference. * All deadlines are 11:59 PM UTC-12:00 (Anywhere On Earth). ----------------------------------------- CONTACT ----------------------------------------- For any questions related to this task, please contact the organizers directly using the following email address: NERShare...(a)gmail.com or join the google group: https://groups.google.com/g/ner_sharedtask2023. ----------------------------------------- SHARED TASK ----------------------------------------- As described, this shared task targets both flat and nested Arabic NER. The subtasks are: Subtask 1: Flat NER In this subtask, we provide the Wojood-Flat train (70%) and development (10%) datasets. The final evaluation will be on the test set (20%). The flat NER dataset is the same as the nested NER dataset in terms of train/test/dev split and each split contains the same content. The only difference in the flat NER is each token is assigned one tag, which is the first high-level tag assigned to each token in the nested NER dataset. Subtask 2: Nestd NER In this subtask, we provide the Wojood-Nested train (70%) and development (10%) datasets. The final evaluation will be on the test set (20%). ----------------------------------------- METRICS ----------------------------------------- The evaluation metrics will include precision, recall, F1-score. However, our official metric will be the micro F1-score. The evaluation of shared tasks will be hosted through CODALAB. Teams will be provided with a CODALAB link for each shared task. -CODALAB link for NER Shared Task Subtask 1 (Flat NER) -CODALAB link for NER Shared Task Subtask 2 (Nestd NER) ----------------------------------------- BASELINES ----------------------------------------- Two baseline models trained on Wojood (flat and nested) are provided: Nested NER baseline: is presented in this article, and code is available in GitHub. The model achieves a micro F1-score of 0.9059 (note that this baseline does not handle nested entities of the same type). Flat NER baseline: same code repository for nested NER (GitHub) can also be used to train flat NER task. Our flat NER baseline achieved a micro F1-score of 0.8785. ----------------------------------------- GOOGLE COLAB NOTEBOOKS ----------------------------------------- To allow you to experiment with the baseline, we authored four Google Colab notebooks that demonstrate how to train and evaluate our baseline models. [1] Train Flat NER: This notebook can be used to train our ArabicNER model on the flat NER task using the sample Wojood data found in our repository. [2] Evaluate Flat NER: this notebook will use the trained model saved from the notebook above to perform evaluation on unseen dataset. [3] Train Nested NER: This notebook can be used to train our ArabicNER model on the nested NER task using the sample Wojood data found in our repository. [4] Evaluate Nested NER: this notebook will use the trained model saved from the notebook above to perform evaluation on unseen dataset. ----------------------------------------- ORGANIZERS ----------------------------------------- - Mustafa Jarrar, Birzeit University - Muhammad Abdul-Mageed, University of British Columbia & MBZUAI - Mohammed Khalilia, Birzeit University - Bashar Talafha, University of British Columbia - AbdelRahim Elmadany, University of British Columbia - Nagham Hamad, Birzeit University - Alaa Omer, Birzeit University

DIPROMATS 2023 CFP: detection and characterization of political propaganda
by Julio Gonzalo 23 Mar '23

23 Mar '23

*** DIPROMATS 2023 Call for participation *** A challenge on the automatic detection and characterization of propaganda techniques in public messages from diplomats and authorities from USA, China, EU and Russia https://sites.google.com/view/dipromats2023 <https://sites.google.com/view/dipromats2023?authuser=0> We are glad to invite you to participate in DIPROMATS 2023, the shared task on propaganda detection at the Iberian Languages Evaluation Forum (IberLEF 2023) Unlike fake news, the detection of propaganda in news and social media has not attracted so much attention from journalists, fact-checkers, or scholars. In our view, this hinders the endeavors against hostile and manipulative information. The deceiving intent of propaganda may be more subtle and devious than disinformation; its content does not have to be false, and its effects may be only discernible through systematic observation over time. As a means by which certain ideas and actions propagate, propaganda involves rhetorical techniques to improve replication. This task proposes a specific approach to detect those techniques based on the language employed by official authorities on Twitter. The corpus provided for the task encompasses tweets in Spanish and English from diplomats of four different international actors: China, Russia, United States, and the European Union. The authorities collected include government accounts, embassies, ambassadors, and other diplomatic profiles such as consuls and missions. This shared task challenges participants to classify tweets according to the following two tasks: Task 1: propaganda identification: The first subtask is a binary classification problem. The systems must decide whether a given tweet contains propaganda techniques. Task 2 & 3: propaganda characterization: The second subtask aims to categorize the type of propaganda. The proposed categorization considers multiple techniques identified in literature that are clustered according to their rhetorical features. We propose a multiclass, multilabel classification task, where systems have to decide, for each tweet, in which of the available categories it fits. The proposed typology can be found here. Evaluation will consider a coarse grain categorization (Task 2) with four classes of propaganda (plus the negative class), and a fine-grained categorization (task 3) with 15 subclasses (plus the negative class). We encourage participation from both academic institutions and industrial organizations. To participate in the task, please fill the registration form at https://sites.google.com/view/dipromats2023/registration <https://sites.google.com/view/dipromats2023/registration?authuser=0> Important Dates: * Registration opens: January 30th, 2023 * Training data released: March 23th, 2023 * Test set release: April 11th, 2023 * Deadline for submitting runs: April 25th, 2023 * Release of evaluation results: May 9th, 2023 * Paper submission deadline: May 30th, 2023 * Camera-ready submissions for organizers: July 6th, 2023 * IberLEF Workshop: September 27, 2023, together with SEPLN 2023 Organizers: Pablo Moral, Universidad Nacional de Educación a Distancia (UNED) Guillermo Marco, Universidad Nacional de Educación a Distancia (UNED) Julio Gonzalo, Universidad Nacional de Educación a Distancia (UNED) Contact: If you have any questions or need more information, please do not hesitate to contact us at dipromats(a)lsi.uned.es

EACL 2023 Call for Diversity & Inclusion Subsidies
by Spandana 23 Mar '23

23 Mar '23

*Overview* EACL 2023 is providing D&I funds for registration, travel/accommodation, caregiving, bandwidth and VPN subsidies. The grants are intended for individuals for whom attending the conference would cause a financial burden or create risks to their safety or privacy. Please apply by 27th March 2023 (2 weeks before the early registration deadline) at https://forms.gle/RqAGjjEjwdvnEqBv7. This call is also available online: https://2023.eacl.org/calls/d-i-subsidies Registration subsidies This is for getting a waiver for EACL registration. If you haven’t already registered for an *ACL in 2023, you would also need to pay the ACL membership registration fee, e.g. $100 for regular. You can also request for ACL membership if that’s applicable. Note that if you are applying for a registration fee waiver, it is expected that you DO NOT register for the conference until you hear from us about your D&I subsidy application. That way, you would not have to ask for a reimbursement, since you would not be charged in the first place. We strongly encourage folks to apply for a volunteership program in order to maximize their chances for getting their registration fees waived. Travel subsidies and pre-paid accommodation We have a limited number of pre-paid accommodation available. These are shared double-rooms in the conference hotel. Please list any special requirements in your application form. We also have a limited budget allocated to support international travel. Please make sure to outline how you will benefit from in-person attendance at this stage of your career. Caregiving and accessibility subsidies We can reimburse caregiving purchases that you need for the conferences. You need to provide receipts for your purchases. These can be babysitting, transportation costs, or other support required for yourself or your dependents, which would ease your participation. If you need any personal or technical assistance to access and navigate the conference due to a disability, we can reimburse you for the cost of it. This holds for example if you need assistance in using the platform for online participation due to a visual impairment. We acknowledge that accessibility needs are highly individual to each participant, so please feel free to reach out to us with any issues you might face in this regard. Bandwidth and VPN subsidies We can reimburse bandwidth or VPN purchases that you need for the conferences. You need to provide receipts for your purchases. Bandwidth subsidies would be for high-speed internet access costs for the duration of the conference only. VPN generally does not cost more than 10 USD per month and could be applied towards participation if you need anonymity to participate completely (for example, for queer folks who might need this for extra security depending on where they live). Selection Criteria Applicants for the subsidy program will be evaluated based on the material they submit in their application packages. Preference will be given to applicants who are presenting a paper in the main conference, the Student Research Workshop, or any of the workshops associated with EACL 2023, and who do not have other means of support. Preferences will be given to residents of under-represented regions and members of marginalized communities (as detailed in the application form). Instructions Applicants for the D&I subsidy Program should fill the application form at: https://forms.gle/RqAGjjEjwdvnEqBv7. *Application deadline:* 27th March 2023 (anywhere on earth) – 2 weeks before the early registration deadline. *Notification of acceptance:* 3rd April 2023 – 1 week before the early registration deadline We aim to send all notifications by the deadline above. However, we will start processing the applications as they come and you may be contacted earlier. *Contact Information* The co-chairs of the Diversity and Inclusion committee can be contacted by email at: eacl2023_div_incl(a)hw.ac.uk

Second CfP: Guarani-Spanish code switching analysis - GUA-SPA at IberLEF 2023
by luischir＠fing.edu.uy 23 Mar '23

23 Mar '23

(apologies for cross posting) *** Second Call for Participation for GUA-SPA at IberLEF 2023 *** GUA-SPA - Guarani-Spanish Code Switching Analysis at IberLEF 2023 News: The training dataset has just been released, and you can send submissions to the development phase! https://codalab.lisn.upsaclay.fr/competitions/11030 Guarani is a South American indigenous language that has been in contact with Spanish and other Indo-European languages for about 500 years, which has resulted in many interesting varieties with different levels of mixture. In Paraguay, according to the most recent census, most of the population of the country speak at least some Guarani, and there is a high prevalence of Guarani-Spanish bilingualism. Bilingual speakers often make use of the two languages at the same time, mixing them in different ways, in a phenomenon called code-switching. We propose a challenge for analyzing code-switched texts in Guarani and Spanish, trying to identify the language used in each span of text, the named entities mentioned in the text, and the way Spanish is used. For this, we will provide a corpus of news and tweets where each token is labeled with an appropriate language or category identifier. Three tasks are presented: * Language identification in code-switched data: identify each token in the text as Guarani, Spanish, mix, named entity, or other categories. * Named entity classification: classify the named entities found in the text as locations, organizations or people. * Spanish code classification: classify the spans in Spanish as code changes or unadapted loans. How to participate: If you want to participate in this task, please join our Codalab competition: https://codalab.lisn.upsaclay.fr/competitions/11030 Important Dates: * March 22nd, 2023: training and development set. Development phase begins. * May 24th, 2023: test set and open for submissions. Evaluation phase begins. * June 7th, 2023: evaluation phase ends. Publication of results. * June 14th, 2023: paper submission. * June 28th, 2023: notification of acceptance. * July 3rd, 2023: camera-ready paper submission. * September 26th, 2023: IberLEF 2023 Workshop.

This full-day "Communication in Human-AI Interaction" (CHAI) workshop welcomes submissions of position papers (8 pages maximum in Springer LNCS format). The workshop will be held as part of the *INTERACT 23 conference* (Aug 28 - Sep 1, York, UK and online, https://interact2023.org/). It will be organized as an interactive work group event, including a design activity and group discussions. Important dates and links * Paper deadline: April 28, 2023 AoE * Notification: May 19, 2023 * Workshop date: between August 28 and September 1, 2023 (TBD) * Workshop website:https://chai-workshop.github.io/ * Submission website:https://easychair.org/conferences/?conf=chai23 *Goal and topics:* Human interactions with AI systems are becoming part of our everyday life. If designed and developed efficiently, these interactions have great potential to enhance human work, abilities, and well-being. Communication, here is the iterative process of establishing shared meaning, is a crucial aspect of successful interaction and has been studied for years, from HCI, AI, and cognitive sciences points of view, among others. The goal of this workshop is to bring together experts from HCI, AI, and Cognitive Sciences to explore and understand the specificities and characteristics of communication in human-AI interactions, as well as the salient principles, methods, and theories one has to consider to build meaningful human-AI communication systems. Topics of interest include but are not limited to: * Blended social contexts, comprising both human and technological communication * Communication in multi-user interaction with intelligent agents * Verbal and non-verbal human-AI communication * Explicit and implicit human-AI communication * Rules of etiquette and social norms in human-AI communication * Communication in human-AI collaboration * Human-AI communication design * Language and communication * Theory of Mind * Common ground * Inclusion and Diversity in Human-AI Communication * Embodied multi-modal communication between humans and physical robots *Format:* The workshop will be a one-day event, envisioned as a collaborative thinking group activity focusing on the challenges surrounding Communication in Human-AI Interaction. The workshop aims at being interactive and will consist of two main parts. First, participants will be invited to collaborate on a design activity. For this activity, participants will be grouped as best as possible by topics and each group will be given the same challenge: analyzing and suggesting a solution to an HAI communication problem. At the end of the activity, each group will report on their solution. Second, we will have group discussions in two phases, for which groups will be shuffled to be cross-disciplinary. Each group will be given a separate topic. The goal of each group will be to identify common interests, open questions, and challenges related to this topic. The groups are shuffled between phases, and participants are encouraged to build on top of the previous groups’ discussion. Each discussion phase will be followed by a quick report of each group. The day will end by a longer plenary discussion during which we will also outline the after-workshop steps. The design activity problem and the discussion topics will be chosen following participants submissions so that they align with the expertise and interest of the workshop participants. By the end of the workshop, we expect to be as close as possible to a common agreement about an outline for the coordinated research agenda, including key points to explore further. Post-workshop, the results will be communicated to a larger audience through various activities, to be synchronized with the participants. *Submission Requirements:* We welcome interested participants to submit position papers stating existing work, conceptual design, or their position with respect to the workshop topics. The submission should also include one or two points of discussion that the participant would like to address during the workshop. Submissions should be made through EasyChair ( https://easychair.org/conferences/?conf=chai23) and be formatted according to the Springer LNCS format, templates available for LaTeX and Word, maximum 8 pages. We strongly encourage authors of position papers to follow the SIGCHI accessibility guidelines.

Call-for-Participation: 1st GANs Task @ ImageCLEF 2023 (Synthetic Medical Images)
by Bogdan Ionescu 23 Mar '23

23 Mar '23

[Apologies for multiple postings] ImageCLEFmedicalGANs (1st edition) Registration: https://www.imageclef.org/2023/medical/gans Run submission: May 10, 2023 Working notes submission: June 5, 2023 CLEF 2023 conference: September 18-21, Thessaloniki, Greece *** CALL FOR PARTICIPATION *** The task is focused on examining the existing hypothesis that GANs are generating medical images that contain the "fingerprints" of the real images used for generative network training. If the hypothesis is correct, artificial biomedical images may be subject to the same sharing and usage limitations as real sensitive medical data. On the other hand, if the hypothesis is wrong, GANs may be potentially used to create rich datasets of biomedical images that are free of ethical and privacy regulations. The participants will test the hypothesis by solving one or several tasks related to the detection of relations between real and artificial biomedical image datasets. *** TASK *** Given a set of real-world medical images comprising 2D axial CT image slices of the heart (including the middle sections and adjacent slices) of patients afflicted with lung #tuberculosis, the task challenges participants to develop #machinelearning solutions to automatically determine which real images were used in training the generator of realistic synthetic examples. *** DATA SET *** The image datasets comprise 2D axial CT image slices of the heart, including the middle sections of the heart and adjacent slices. These images are obtained from patients afflicted with Lung Tuberculosis and are stored in the form of 8 bit/pixel PNG images with dimensions of 256x256 pixels. The development dataset comprises three distinct sets of images. One set contains images that were generated using a GAN, while the other two sets are comprised of real images. The first of these real image sets contains images that were used during the algorithm's training process. The second set consists of real images that were not used during the training process. Test dataset is a collection of two image sets. The first set contains 10,000 images that have been generated, while the second set is made up of a combination of 200 real images that were either used or unused during the training process. *** IMPORTANT DATES *** - Run submission: May 10, 2023 - Working notes submission: June 5, 2023 - CLEF 2023 conference: September 18-21, Thessaloniki, Greece (https://clef2023.clef-initiative.eu/) *** OVERALL COORDINATION *** Serge Kozlovski, Belarusian Academy of Sciences, Belarus Vassili Kovalev, Belarusian Academy of Sciences, Belarus Ihar Filipovich, Belarus State University, Belarus Alexandra Andrei, Politehnica University of Bucharest, Romania Ioan Coman, Politehnica University of Bucharest, Romania Bogdan Ionescu, Politehnica University of Bucharest, Romania Henning Müller, University of Applied Sciences Western Switzerland, Switzerland *** ACKNOWLEDGEMENT *** Alexandra Andrei, Ioan Coman, Bogdan Ionescu, and Henning Müller contribution is supported under the H2020 AI4Media "A European Excellence Centre for Media, Society and Democracy" project, contract #951911 https://www.ai4media.eu/.
