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.

23 Mar '23

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/.

Workshop on Language Corpora in Australia -- 3 July 2023 (online, via Zoom)
by li.nguyen＠anu.edu.au 23 Mar '23

23 Mar '23

3 July 2023 (online, via Zoom) Organisers: Catherine Travis & Li Nguyen (ANU; Language Data Commons of Australia (LDaCA)) Over decades of work in Australia, significant collections of language data have been amassed, including of varieties of Australian English, Australian migrant languages, Australian Indigenous languages, sign languages and others. These collections represent a trove of knowledge not only of language in Australia, but also of Australia’s social and cultural history. And yet, not all are well known and many lack published descriptions. The purpose of this workshop is to provide an opportunity to share information about existing language corpora in Australia, with a view to producing a special issue of the Australian Journal of Linguistics that introduces a selection of these corpora, explores how they can contribute to our understanding of language, society, and history in Australia, and considers avenues that such corpora open up for future research. This workshop is being run as part of the Language Data Commons of Australia (LDaCA), which is working to build national research infrastructure for the Humanities and Social Sciences, facilitating access to and use of digital language corpora for linguists, scholars across the Humanities and Social Sciences, and non-academics. Abstract submission For a 20 min presentation, please submit a 250-300 word abstract in English (excluding references). The presentation should include the following information: · Speech community/fieldsite: Describe the location of the community and/or their brief history in Australia, the languages spoken and their current status. · Corpus design principles: Specify the sample size, sociolinguistic background of the participants, method of data collection and/or genre (e.g. sociolinguistic interviews, natural conversations, oral histories, elicited data, etc.); data format (written/spoken/audio/video, etc.) and where it is stored. · Corpus findings and implications: Summarise some key findings from the corpus and discuss other insights that might be obtained from the data in current or future work. Important dates 22 May Abstracts due 5 June Notification of acceptance 3 July Workshop How to Submit: Please submit your abstract by 22 May on https://forms.gle/1pwxVVmUV5hCCZ997 Inquiries: Please contact either Catherine Travis or Li Nguyen

Training set released! IberLEF 2023 Task - FinancES. Financial Targeted Sentiment Analysis in Spanish
by Rafael Valencia Garcia 23 Mar '23

23 Mar '23

CALL FOR PARTICIPATION IBERLEF 2023 Task - FinancES. Financial Targeted Sentiment Analysis in Spanish Training set released! Held as part of iberLEF 2023 <https://sites.google.com/view/iberlef-2023>, a shared evaluation campaign for Natural Language Processing (NLP) systems in Spanish and other Iberian languages September 26th 2023, Jaen Codalab link: https://codalab.lisn.upsaclay.fr/competitions/10052 Dear All, We are inviting researchers and students to participate in the shared-task FinancES. Financial Targeted Sentiment Analysis in Spanish held as part of iberLEF 2023, shared evaluation campaign for Natural Language Processing (NLP) systems in Spanish and other Iberian languages. This shared task aims to explore targeted sentiment analysis in the financial domain. Specifically, the approach adopted here is grounded in the field of microeconomics. In this regard, Bowles (2004) explains the role of economic agents, that is to say, individuals or organizations impacting the economy. The author states that the main microeconomic agents in the capital market are consumers (households/individuals), companies (firms), governments, and central banks. Consequently, in order to develop a sentiment analysis method where different viewpoints are considered, three different perspectives are included: (1) economic target of the news item; (2) individual economic agent: companies; and (3) individual economic agent: consumers –the target is the sector where the economic fact applies, and companies produce the goods and services that households/individuals consume. From these three viewpoints, the news item has an impact on the target and the economic agents which are considered as positive, negative, or neutral. With all, two tasks are proposed. On the one hand, a task combining the challenges of aspect-term extraction for identifying the target entity in text, and aspect-based sentiment classification for determining the sentiment polarity towards the target. On the other hand, a task devoted to assessing the impact of a news headline on both other economic agents, namely, companies and consumers. The participants will be provided development, development_test, training and test datasets in Spanish. The dataset for this task is composed of news headlines written in Spanish collected from digital newspapers specialized in economic, financial and political news. The dataset is labeled with the target entity and the sentiment polarity on three dimensions: target, companies, and consumers. That is, given a headline, it has been manually classified as positive, neutral, or negative for three specific entities: (1) target entity (i.e., the specific company or asset where the economic fact applies), (2) companies (i.e., the entities producing the goods and services that others consume), and (3) consumers (i.e., households/individuals). Each headline was annotated by three members of the organization committee. In case of disagreement, the annotators discussed the special case and, if no agreement was reached, the headline was discarded. During this first step, we compiled about 14k headlines, the headlines with a short length or those that did not specify a target entity were filtered out. The final dataset is composed of 8k-10k news headlines. For the shared tasks, training and test sets will be released (80%-20%). Today, we have released the training dataset that can be found in the "Files" subsection of the "Participate" tab. It is worth mentioning that this dataset includes all the instances that were also released during the Practice stage; so, it is not needed to combine both datasets. Finally, remember that the CodaLab competition is open to submit your results with the development dataset provided. This dataset is also available in the same section as the training dataset.
