*CheckThat! Lab at CLEF 2023* We invite you to participate in the 2023 edition of the CheckThat! Lab at CLEF 2023. This year, we feature five tasks ---one follow-up and four new--- that correspond to important components within and around the full fact-checking pipeline in multiple languages: *Task 1 Check-worthiness in tweets*: This is the sixth round of the check-worthiness task. It allows us to reduce the workload of listening to social media for tweets and claims that would require the attention of a journalist. We offer two task modalities. Subtask 1A: Multimodal tweets including text and picture (for the first time!). Available in *Arabic *and English. Subtask 1B: Unimodal tweets and claims. Available in *Arabic*, English and Spanish. Subtask 1C: US political debates, text only. Available in English *Task 2 Subjectivity in news articles*: Distinguish whether a sentence from a news article expresses the subjective view of the author behind it or presents an objective view on the covered topic instead. Available in *Arabic*, Dutch, English, Italian, German, and Turkish. *Task 3 Political bias of news articles and news media:* Detect political bias of news reporting at the article and at the media level. It includes two subtasks: Subtask 3A: Given an article, classify its political leaning as left, center or right. Subtask 3B: Given the URL to a news outlet (e.g., www.cnn.com), predict the overall political bias of that news outlet as left, center or right leaning. Available in English. *Task 4 Factuality of reporting of news media:* Identify the factuality of reporting at the media level. Given the URL to a news outlet the task asks to predict the factuality of reporting of that news outlet: low, mixed, and high. Available in English. *Task 5 Authority finding on twitter: *Given a tweet stating a rumor, a model has to retrieve a ranked list of authority Twitter accounts that can help verify the rumor; i.e. they may tweet evidence that supports or denies the rumor. Available in Arabic.

CFP Slav-NER Shared Task: Call for Participation: 4th Slav-NER SharedTask on Named Entities in Slavic Languages
by Roman Yangarber 07 Feb '23

07 Feb '23

* Call for Participation * * The 4thSlav-NER Shared Task on Named Entities in Slavic Languages: <http://bsnlp.cs.helsinki.fi/shared-task.html> Recognition, Normalization, Classification and Cross-Lingual Linking <http://bsnlp.cs.helsinki.fi/shared-task.html> ** co-located with the Slav-NLP <http://bsnlp.cs.helsinki.fi/>Workshop, EACL 2023 http://bsnlp.cs.helsinki.fi/shared-task.html <http://bsnlp.cs.helsinki.fi/shared-task.html> TASK DESCRIPTION: The 4thSlav-NER Shared Task focuses on Named Entities in Slavic languages. Due to rich inflection, free word order, derivation, and other phenomena common to the Slavic languages, work on Named Entities poses important challenges. Fostering research & development on the problems of Named Entities — detecting names, lemmatization (normalization), classification, and cross-lingual matching — is crucial for information access and wider use of NLP in Slavic languages. The 4thSlav-NER Shared Task covers three languages: * Czech, * Polish, * Russian. and five types of named entities: * persons, * locations, * organizations, * events, * products. For information about training and test data, guidelines, and participation, please see the Shared Task Home Page. <http://bsnlp.cs.helsinki.fi/shared-task.html> IMPORTANT: Participants are NOT required to perform all tasks or for all languages. For example, a monolingual entry, without lemmatization of the names, can participate. The Shared Task focuses on cross-lingual extraction of named entities — the systems should recognize, classify, and extract all mentions of a name in a document; detecting the positionof each name mention is NOT required. Name mentions should be lemmatized, and mentions referring to the same real-world object should be linked across documents and languages. The text collection consists of sets of documents retrieved from the Web, each set about a certain major entity or event. The corpus was collected by crawling the Web and parsing the HTML documents. For background, see the details about the1stedition (2017) <http://bsnlp-2017.cs.helsinki.fi/shared_task.html>, 2ndedition (2019) <http://bsnlp.cs.helsinki.fi/bsnlp-2019/shared_task.html>and the3rdedition (2021) <http://bsnlp.cs.helsinki.fi/shared-task.html>of this shared task.

First Call for Papers: The 7th Joint SIGHUM Workshop on Computational Linguistics for Cultural Heritage, Social Sciences, Humanities and Literature
by Stan Szpakowicz 06 Feb '23

06 Feb '23

*LaTeCH-CLfL 2023:** **The 7th Joint SIGHUM Workshop on Computational Linguistics for Cultural Heritage, Social Sciences, Humanities and Literature* to be held in May 2023 in conjunction with EACL 2023 in Dubrovnik, Croatia. https://sighum.wordpress.com/events/latech-clfl-2023/ First Call for Papers (with apologies for cross-posting) Organisers: Stefania Degaetano-Ortlieb, Anna Kazantseva, Nils Reiter, Stan Szpakowicz LaTeCH-CLfL 2023 is the seventh in a series of meetings for NLP researchers who work with data from the broadly understood arts, humanities and social sciences, and for specialists in those disciplines who apply NLP techniques in their work. The workshop continues a long tradition of annual meetings. The SIGHUM Workshops on Language Technology for Cultural Heritage, Social Sciences, and Humanities (LaTeCH) ran ten times in 2007-2016. The five Workshops on Computational Linguistics for Literature (CLfL) took place in 2012-2016. The first six joint workshops (LaTeCH-CLfL) were held in 2017-2022. *Topics and Content* In the Humanities, Social Sciences, Cultural Heritage and literary communities, there is increasing interest in, and demand for, NLP methods for semantic and structural annotation, intelligent linking, discovery, querying, cleaning and visualization of both primary and secondary data. This is even true of primarily non-textual collections, given that text is also the pervasive medium for metadata. Such applications pose new challenges for NLP research: noisy, non-standard textual or multi-modal input, historical languages, vague research concepts, multilingual parts within one document, and so no. Digital resources often have insufficient coverage; resource-intensive methods require (semi-)automatic processing tools and domain adaptation, or intense manual effort (e.g., annotation). Literary texts bring their own problems, because navigating this form of creative expression requires more than the typical information-seeking tools. Examples of advanced tasks include the study of literature of a certain period, author or sub-genre, recognition of certain literary devices, or quantitative analysis of poetry. NLP methods applied in this context not only need to achieve high performance, but are often applied as a first step in research or scholarly workflow. That is why it is crucial to interpret model results properly; model interpretability might be more important than raw performance scores, depending on the context. More generally, there is a growing interest in computational models whose results can be used or interpreted in meaningful ways. It is, therefore, of mutual benefit that NLP experts, data specialists and Digital Humanities researchers who work in and across their domains get involved in the Computational Linguistics community and present their fundamental or applied research results. It has already been demonstrated how cross-disciplinary exchange not only supports work in the Humanities, Social Sciences, and Cultural Heritage communities but also promotes work in the Computational Linguistics community to build richer and more effective tools and models. Topics of interest include, but are not limited to, the following: • adaptation of NLP tools to Cultural Heritage, Social Sciences, Humanities and literature; • automatic error detection and cleaning of textual data; • complex annotation schemas, tools and interfaces; • creation (fully- or semi-automatic) of semantic resources; • creation and analysis of social networks of literary characters; • discourse and narrative analysis/modelling, notably in literature; • emotion analysis for the humanities and for literature; • generation of literary narrative, dialogue or poetry; • identification and analysis of literary genres; • linking and retrieving information from different sources, media, and domains; • modelling dialogue literary style for generation; • modelling of information and knowledge in the Humanities, Social Sciences, and Cultural Heritage; • profiling and authorship attribution; • search for scientific and/or scholarly literature; • work with linguistic variation and non-standard or historical use of language. *Information for Authors* We invite papers on original, unpublished work in the topic areas of the workshop. In addition to long papers, we will consider short papers and system descriptions (demos). We also welcome position papers. • Long papers, presenting completed work, may consist of up to eight (8) pages of content plus additional pages of references (just two if possible -:). The final camera-ready versions of accepted long papers will be given one additional page of content (up to 9 pages) so that reviewers’ comments can be taken into account. • A short paper / demo presenting work in progress, or the description of a system, and may consist of up to four (4) pages of content plus additional pages of references (one if you can). Upon acceptance, short papers will be given five (5) content pages in the proceedings. • A position paper — clearly marked as such — should not exceed eight (8) pages including references. All submissions are to use the EACL stylesheets (for LaTeX / Overleaf and MS Word), posted at https://2023.eacl.org/calls/styles. Papers should be submitted electronically, only in PDF, via the LaTeCH-CLfL2023 submission website on the SoftConf pages (we will publish the link as soon as we have it). Reviewing will be double-blind. Please do not include the authors’ names and affiliations, or any references to Web sites, project names, acknowledgements and so on — anything that immediately reveals the authors’ identity. Self-references should be kept to a reasonable minimum, and anonymous citations cannot be used. Accepted papers will be published in the workshop proceedings available as usual in the ACL Anthology. *Important Dates* (tentative) Papers due: February 13, 2023 Notification of acceptance: March 13, 2023 Camera-ready papers due: March 27, 2023 Workshop date: May 2 or May 6, 2023 *More on the organisers* Stefania Degaetano-Ortlieb, Language Science and Technology, Saarland University Anna Kazantseva, National Research Council Canada Nils Reiter, Department for Digital Humanities, University of Cologne Stan Szpakowicz, School of Electrical Engineering and Computer Science, University of Ottawa *Contact* latech-clfl(a)googlegroups.com

by Chi-kiu (Jackie) Lo 06 Feb '23

06 Feb '23

*Apologies for cross-posting* Postdoctoral Fellowships, National Research Council Canada The NRC Advantage Great Minds. One Goal. Canada's Success. The National Research Council of Canada (NRC) is the Government of Canada's largest research organization supporting industrial innovation, the advancement of knowledge and technology development. We collaborate with over 70 colleges, universities and hospitals annually, work with 800 companies on their projects, and provide advice or funding to over 8000 Small and Medium-sized Enterprises (SMEs) each year. We bring together the brightest minds to deliver tangible impacts on the lives of Canadians and people around the world. And now, we want to partner with you. Let your expertise and inspirations make an impact by joining the NRC. At the NRC, we know that diversity enables excellence in research and innovation. We are committed to a diverse and representative workforce, a safe and respectful work environment, and contributing to a more inclusive Canadian innovation system. We welcome all qualified applicants and encourage you to complete the employment equity self-declaration questions during the job application process. The Program (https://nrc.canada.ca/en/corporate/careers/postdoctoral-fellowship-program) The NRC’s Postdoctoral Fellowship program offers PDFs access to unique world-class facilities and the opportunity to work alongside multi-disciplinary teams of expert researchers and technicians on projects of critical importance to Canada. PDFs will carry out research on innovative research projects, with opportunities for career development (publications and/or industry interaction). Project I: Multilingual Machine Translation for Transforming Response to Refugees and Forced Migration There are more than 103 million displaced persons in the world today. While English remains the global language of policy exchange and studies, significant knowledge on refugee issues appears in other languages spoken where forced migration occurs. Machine translation (MT) improves the accessibility of relevant publications across different languages and facilitates fair and inclusive discussion among international stakeholders. However, challenges with in-domain multilingual neural machine translation (MNMT) limits the availability of efficient, affordable and manageable MT with usable translation quality for forced migration responses. The successful fellow will collaborate with external collaborators to create an in-domain multiway parallel corpus on forced migration. The corpus will then enable research on MNMT and its adaptation to the forced migration domain. Finally, the fellow will research on training MNMT to translate unseen languages efficiently with minimal resources. Having compassion about refugees and forced migration issues and ease in meeting with the forced migration communities around the world would be beneficial in this role. Due to the topic of the project, the successful candidate may frequently be working on and with data and clients about refugees and forced migration issues which may cause triggering responses. Education Requirement PhD in Computer Science, Computational Linguistics or related discipline. Experience Requirement • Hands on experience in end-to-end MT modelling and training. • Research experience in MNMT. • Research experience in parallel corpus building, domain adaptation, non-English centric MT or low resource MT. *Asset * *Assets are “nice-to-have” expertise and competencies we’re interested in. Not having them should not prevent you from applying.* • Ability to read Arabic, Spanish, Russian, Ukrainian, Burmese or Pashto would be an asset.

Project II: Audio search and topic detection for audiovisual corpora in a polysynthetic Indigenous language NRC is searching for a recent PhD graduate to develop techniques for speech recognition and/or synthesis, using untranscribed audio corpora of speech in Indigenous, polysynthetic languages. Many such languages spoken in Canada have substantial collections of recorded speech. Language activists, academic linguists, and radio broadcasters have been recording the speech of Elders for decades, but so far only a small fraction has been catalogued, annotated, and transcribed. Thus, there are thousands of hours of recorded speech in Indigenous languages that are inaccessible in practice. The project will focus primarily on Inuktut, Cree, and/or Iroquoian languages. Alternative/additional languages are a possibility if appropriate datasets become available. Education Requirement PhD in computational linguistics, computer science or a related field. Experience Requirement • Experience in speech/natural language processing (NLP) technology. • Experience in either automatic speech recognition or speech synthesis. • Experience working with Indigenous languages and communities.

6th ESAO Webinar, Tuesday, February 14th, 2023 -- Call for Participation
by Cassia 06 Feb '23

06 Feb '23

Dear all, The Educational Series on Applied Ontology (ESAO) [1] is open for everyone and welcomes students, researchers and practitioners alike. The sixth of its regular webinar sessions will be held on *Tuesday, 14th, 2023 at 10:00 EST / 15:00 UTC / 16:00 CET / 17:00 SAST* via a Zoom meeting (full connection details at the end of this message): https://univ-tlse2.zoom.us/j/94831243675?pwd=NXpaalpLalQ5UTd3emNUR2VTNGpRZz… No registration needed; please find full connection details at the end of this message. Program ------- * 10:00-10:30 EST / 15:00-15:30 UTC / 16:00-16:30 CET / 17:00-17:30 SAST Title: Using Abduction to Explain Missing Entailments in OWL Ontologies Patrick Koopmann, TU Dresden Abstract: With increasing complexity, understanding and debugging ontologies becomes a challenging task without the appropriate tool support. In particular, inferences performed by a reasoner may not always be straight-forward, meaning they may produce entailments that we did not expect, or fail to produce entailments that we did expect. While there are different techniques to explain entailments, this talk focusses on the problem of explaining why something does not follow from the ontology. In particular, we explain how abduction may be used towards solving this issue, and discuss challenges and solutions for performing abduction in practice. Series Description ------------------ The IAOA [2] has created ESAO, a new educational effort directed towards topics of Applied Ontology, primarily established basics and foundations. The series is inspired by the Interdisciplinary Schools on Applied Ontology (ISAO) [3] (whose next edition will be held in 2023). ESAO is complementary in format and its overall approach. The goal is to provide a combination of an archive of educational material (e.g., short video lectures) and a series of webinars for presenting and discussing that material.

by firojalam＠gmail.com 06 Feb '23

06 Feb '23

We invite you to participate in the 2023 edition of the CheckThat! Lab at CLEF 2023. This year, we feature five tasks ---one follow-up and four new--- that correspond to important components within and around the full fact-checking pipeline in multiple languages: Task 1 Check-worthiness in tweets: This is the sixth round of the check-worthiness task. It allows us to reduce the workload of listening to social media for tweets and claims that would require the attention of a journalist. We offer two task modalities.. Subtask 1A: Multimodal tweets including text and picture (for the first time!). Available in Arabic and English. Subtask 1B: Unimodal tweets and claims. Available in Arabic, English and Spanish. Subtask 1C: US political debates, text only. Available in English Task 2 Subjectivity in news articles: Distinguish whether a sentence from a news article expresses the subjective view of the author behind it or presents an objective view on the covered topic instead. Available in Arabic, Dutch, English, Italian, German, and Turkish. Task 3 Political bias of news articles and news media. Detect political bias of news reporting at the article and at the media level. It includes two subtasks: Subtask 3A: Given an article, classify its political leaning as left, center or right. Subtask 3B: Given the URL to a news outlet (e.g., www.cnn.com), predict the overall political bias of that news outlet as left, center or right leaning. Available in English. Task 4 Factuality of reporting of news media. Identify the factuality of reporting at the media level. Given the URL to a news outlet the task asks to predict the factuality of reporting of that news outlet: low, mixed, and high. Available in English. Task 5 Authority finding on twitter. Given a tweet stating a rumor, a model has to retrieve a ranked list of authority Twitter accounts that can help verify the rumor; i.e. they may tweet evidence that supports or denies the rumor. Available in Arabic.
