There are two options for submissions that are i) Softconf page of the workshop: https:// <https://www.softconf.com/m/icspcc2022> softconf.com/emnlp2022/case2022 and ii) ACL Rolling review (ARR): https://aclrollingreview.org/dates. ************************************************************************************ Event extraction has long been a challenge for the natural language processing (NLP) community as it requires sophisticated methods in defining event ontologies, creating language resources, domain specific grammars, developing Machine Learning models and other algorithmic approaches for various event-detection- specific tasks, such entity detection, semantic labeling, event classification and clustering and others (Pustojevsky et al. 2003; Boroş, 2018; Chen et al. 2021). Social and political scientists have been working to create socio-political event (SPE) databases such as ACLED, EMBERS, GDELT, ICEWS, MMAD, PHOENIX, POLDEM, SPEED, TERRIER, and UCDP following similar steps for decades. These projects and the new ones increasingly rely on machine learning (ML), deep learning (DL), and NLP methods to deal better with the vast amount and variety of data in this domain (Hürriyetoğlu et al. 2020). Unfortunately, automated approaches suffer from major issues like bias, limited generalizability, class imbalance, training data limitations, and ethical issues that have the potential to affect the results and their use drastically (Lau and Baldwin 2020; Bhatia et al. 2020; Chang et al. 2019). Moreover, the results of the automated systems for SPE information collection have neither been comparable to each other nor been of sufficient quality (Wang et al. 2016; Schrodt 2020). SPEs are varied and nuanced. Both the political context and the local language used may affect whether and how they are reported. We invite contributions from researchers in computer science, NLP, ML, DL, AI, socio-political sciences, conflict analysis and forecasting, peace studies, as well as computational social science scholars involved in the collection and utilization of SPE data. This includes (but is not limited to) the following topics 1) Extracting events in and beyond a sentence, event coreference resolution, 2) New datasets, training data collection, and annotation for event information, 3) Event-event relations, e.g., subevents, main events, causal relations, 4) Event dataset evaluation in light of reliability and validity metrics, 5) Defining, populating, and facilitating event schemas and ontologies, 6) Automated tools and pipelines for event collection related tasks, 7) Lexical, syntactic, discursive, and pragmatic aspects of event manifestation, 8) Methodologies for development, evaluation, and analysis of event datasets, 9) Applications of event databases, e.g. early warning, conflict prediction, policymaking, 10) Estimating what is missing in event datasets using internal and external information, 11) Detection of new SPE types, e.g. creative protests, cyberactivism, COVID19 related, 12) Release of new event datasets, 13) Bias and fairness of the sources and event datasets, 14) Ethics, misinformation, privacy, and fairness concerns pertaining to event datasets, and 15) Copyright issues on event dataset creation, dissemination, and sharing. 16) We encourage submissions of new system description papers on our available benchmarks (ProtestNews @ CLEF 2019, AESPEN @ LREC 2020, and CASE @ 2021). Please contact the organizers if you would like to access the data. The proceedings of the previous editions should be indicative of what we cover: ProtestNews @ CLEF 2019 (http://ceur-ws.org/Vol-2380/), AESPEN @ ACL 2020 (https://aclanthology.org/volumes/2020.aespen-1/), CASE @ ACL-IJCNLP 2021 (https://aclanthology.org/volumes/2021.case-1/). **** Shared tasks **** Task 1- Multilingual protest news detection: This is the same shared task organized at CASE 2021 (For more info: https://aclanthology.org/2021.case-1.11/) But this time there will be additional data and languages at the evaluation stage.

Github: https://github.com/emerging-welfare/case-2022-multilingual-event Task 2- Automatically replicating manually created event datasets: The participants of Task 1 will be invited to run the systems they will develop to tackle Task 1 on a news archive (For more info https://aclanthology.org/2021.case-1.27/). Contact person: Hristo Tanev ( htanev@gmail.com). Github: https://github.com/emerging-welfare/case-2022-multilingual-event Task 3- Event causality identification: Causality is a core cognitive concept and appears in many natural language processing (NLP) works that aim to tackle inference and understanding. We are interested to study event causality in news, and therefore, introduce the Causal News Corpus. The Causal News Corpus consists of 3,559 event sentences, extracted from protest event news, that have been annotated with sequence labels on whether it contains causal relations or not. Subsequently, causal sentences are also annotated with Cause, Effect, and Signal spans. Our two subtasks (Sequence Classification and Span Detection) work on the Causal News Corpus, and we hope that accurate, automated solutions may be proposed for the detection and extraction of causal events in news.
