************************************************************************************

Nowadays, the unprecedented quantity of easily accessible data on social, political, and economic processes offers ground-breaking potential in guiding data-driven analysis in social and human sciences and in driving informed policy-making processes. Governments, multilateral organizations, local and global NGOs, and present an increasing demand for high-quality information about a wide variety of events ranging from political violence, environmental catastrophes, and conflict, to international economic and health crises (Coleman et al. 2014; Porta and Diani, 2015) to prevent or resolve conflicts, provide relief for those that are afflicted, or improve the lives of and protect citizens in a variety of ways. Black Lives Matter protests and conflicts in Syria are only two examples where we must understand, analyze, and improve the real-life situations using such data. Finally, these efforts respond to “growing public interest in up-to-date information on crowds” as well.

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, and developing algorithmic approaches (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). Automation offers scholars not only the opportunity to improve existing practices, but also to vastly expand the scope of data that can be collected and studied, thus potentially opening up new research frontiers within the field of SPEs, such as political violence and social movements. But automated approaches as well suffer from major issues like bias, 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. Therefore, all steps of information collection (event definition, language resources, and manual or algorithmic steps) may need to be constantly updated, leading to a series of challenging questions: Do events related to minority groups are represented well? Are new types of events covered? Are the event definitions and their operationalization comparable across systems? This workshop aims to seek answers to these questions as well. Inspiring innovative technological and scientific solutions for tackling these issues and quantifying the quality of the results. 

 

 

Call for Papers

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. Social and political scientists will be interested in reporting and discussing their approaches and observing what the state-of-the-art text processing systems can achieve for their domain. Computational scholars will have the opportunity to illustrate the capacity of their approaches in this domain and benefit from being challenged by real-world use cases. Academic workshops specific to tackling event information in general or for analyzing text in specific domains such as health, law, finance, and biomedical sciences have significantly accelerated progress in these topics and fields, respectively. However, there has not been a comparable effort for handling SPEs. We fill this gap. We invite work on all aspects of automated coding and analysis of SPEs and events in general from mono- or multi-lingual text sources. This includes (but is not limited to) the following topics

  • Extracting events in and beyond a sentence, event coreference resolution
  • New datasets, training data collection and annotation for event information
  • Event-event relations, e.g., subevents, main events, causal relations
  • Event dataset evaluation in light of reliability and validity metrics
  • Defining, populating, and facilitating event schemas and ontologies
  • Automated tools and pipelines for event collection related tasks
  • Lexical, syntactic, discursive, and pragmatic aspects of event manifestation
  • Methodologies for development, evaluation, and analysis of event datasets
  • Applications of event databases, e.g. early warning, conflict prediction, policymaking 
  • Estimating what is missing in event datasets using internal and external information
  • Detection of new SPE types, e.g. creative protests, cyber activism, COVID19 related
  • Release of new event datasets
  • Bias and fairness of the sources and event datasets
  • Ethics, misinformation, privacy, and fairness concerns pertaining to event datasets
  • Copyright issues on event dataset creation, dissemination, and sharing

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.

Contact person: Hristo Tanev (htanev@gmail.com). Github: https://github.com/zavavan/case2022_task2, please also see  https://github.com/emerging-welfare/case-2022-multilingual-event 

 

TASK 3: EVENT CAUSALITY IDENTIFICATION:

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.

  2. Scott Althaus (https://pol.illinois.edu/directory/profile/salthaus): is Merriam Professor of Political Science, Professor of Communication, and Director of the Cline Center for Advanced Social Research at the University of Illinois Urbana-Champaign. He also has faculty appointments with the School of Information Sciences and the National Center for Supercomputing Applications. His work with the Cline Center applies text analytics methods and Artificial Intelligence algorithms to extract insights from millions of news stories in ways that produce new forms of knowledge that advance societal well-being around the world. His own research interests explore the communication processes that support political accountability in democratic societies and that empower political discontent in non-democratic societies. His interests focus on four areas of inquiry: (1) how journalists construct news coverage about public affairs, (2) how leaders attempt to shape news coverage for political advantage, (3) how citizens use news coverage for making sense of public affairs, and (4) how the opinions of citizens are communicated back to leaders. He has particular interests in popular support for war, data science methods for extreme-scale analysis of news coverage, cross-national comparative research on political communication, the psychology of information processing, and communication concepts in democratic theory. His current projects include using data mining methods to help journalists cover terrorist attacks in responsible ways, a solo-authored book manuscript to be published by Cambridge University Press about the dynamics of popular support for war in the United States, and a co-authored book manuscript (with Tamir Sheafer and Gadi Wolfsfeld) in press with Oxford University Press on understanding the role of media in supporting governmental accountability and increasing the government’s responsiveness to citizen needs.

    Title: A total error approach to validating event data that is transparent, scalable, and practical to implement (Presented by Scott Althaus on behalf of the Cline Center for Advanced Social Research)

     

    Abstract: There are at least two reasonable ways to make your way toward where you want to go: looking down to carefully place one foot in front of the other, and looking up to focus on where you hope to arrive. Looking up beats looking down if there’s a particular destination in mind, and for constructing valid event data that destination usually takes the form of high-quality human judgment. Yet many approaches to generating event data on protests and acts of political violence using fully-automated systems implicitly adopt a “looking down” approach by benchmarking validity as a series of incremental improvements over prior algorithmic efforts. And even those efforts that adopt a “looking up” approach often treat human-generated gold standard data as if it was prima facie valid, without ever testing or confirming the accuracy of this assumption. It stands to reason that if we want to automatically produce valid event data that approaches the validity of human judgment, then we also need to validate the human judgment tasks that provide the point of comparison. But because of obvious difficulties in implementing such a rigorous assessment within the time and budget constraints of typical research projects, this more rigorous double-validation approach is rarely attempted.

     

    This presentation outlines a “looking up” approach for double-validating fully-automated event data developed by the Cline Center for Advanced Social Research at the University of Illinois Urbana-Champaign (USA), illustrates that approach with a test of the precision and recall for two widely-used event classification systems (the PETRARCH-2 coder used in Phoenix and TERRIER, as well as the BBN ACCENT coder used in W-ICEWS), and demonstrates the utility of the approach for developing fully-automated event data algorithms with levels of validity that approach the quality of human judgment.

     

    The first part of the talk reviews the Cline Center’s total error framework for identifying 19 types of error that can affect the validity of event data and addresses the challenge of applying a total error framework when authoritative ground truth about the actual distribution of relevant events is lacking (Althaus, Peyton, and Shalmon, 2022). We argue that carefully constructed gold standard datasets can effectively benchmark validity problems even in the absence of ground truth data about event populations. We propose that a strong validity assessment for event data should, at a minimum, possess three characteristics. First, there should be a standard describing ideal data; a gold standard that, in the best case, takes the form of ground truth. Second, there should be a direct “apples to apples” comparison of outputs from competing methods given identical input. Third, the test should use appropriate metrics for measuring agreement between the gold standard and data produced by competing approaches.

     

    The second part of the talk presents the results of a validation exercise meeting all three criteria that is applied to two algorithmic event data pipelines: the Python Engine for Text Resolution and Related Coding Hierarchy (PETRARCH-2) and the BBN ACCENT event coder. It then reviews a recent Cline Center project that has built a fully-automated event coder which produces dramatic improvements in validity over both PETRARCH-2 and BBN ACCENT by leveraging the total error framework and a reliance on the double-validation approach using high-quality gold standard benchmark datasets.

     

     

  3. Thien Huu Nguyen (https://ix.cs.uoregon.edu/~thien/) is an assistant professor in the Department of Computer and Information Science at the University of Oregon. He obtained his Ph.D. in natural language processing (NLP) at New York University (working with Ralph Grishman) and did a postdoc at the University of Montreal (working with Yoshua Bengio). Thien’s research areas involve information extraction, language grounding, and deep learning where he developed one of the first deep learning models for entity recognition, relation extraction, and event extraction. His current research explores multi-domain and multilingual NLP that aims to learn transferable representations to perform information extraction tasks over different domains and languages. Thien is the director of the NSF IUCRC Center for Big Learning (CBL) at the University of Oregon. His research has been supported by NSF, IARPA, Army Research Office, Adobe Research, and IBM Research.

    Title: Event Extraction in the Era of Large Language Models: Structure Induction and Multilingual Learning

     

    Abstract: Events such as protests, disease outbreaks, and natural disasters are prevalent in text from different languages and domains. Event Extraction (EE) is an important task of Information Extraction that aims to identify events and their structures in unstructured text. The last decade has witnessed significant progress for EE research, featuring deep learning and large language models as the state-of-the-art technologies. However, a key issue of existing EE methods involves modeling input text sequentially to solve each EE tasks separately, thus limiting the abilities to encode long text and capture various types of dependencies to improve EE performance. In this talk, I will present some of our recent efforts to address this issue where text structures are explicitly learned to realize important objects and their interactions to facilitate the predictions for EE.

     

    In addition, current EE research still mainly focuses on a few popular languages, e.g., English, Chinese, Arabic, and Spanish, leaving many other languages unexplored for EE. In this talk, I will also introduce our current research focus on developing evaluation benchmarks and models to extend EE systems to multiple new languages, i.e., multilingual and cross-lingual learning for EE. Finally, I will highlight some research challenges that can be studied in future work for EE.
