in conjunction with The Web Conference (WWW) 2021

April 19-23 2021, Ljubljana, Slovenia

-----------------------------------------------------------------------------------------------------------------------------
The modern society faces an unprecedented number of events that impact countries, communities and economies around the globe, across language, country and community borders. Recent examples include sudden or unexpected events such as terrorist attacks, political shake-ups such as Brexit as well as longer ongoing and evolving topics such as the migration crisis in Europe that regularly spawn events of global importance affecting local communities. These developments result in a vast amount of event-centric, multilingual information available from heterogeneously sources on the Web, in the Web of Data, within Knowledge Graphs, in social media, inside Web archives and in the news sources. Such event-centric information differs across sources, languages and communities, potentially reflecting community-specific aspects, opinions, sentiments and bias.

The theme of the CLEOPATRA workshop – event-centric multilingual analytics – includes a variety of interdisciplinary challenges related to analysis, interaction with and interpretation of vast amounts of event-centric textual, semantic and visual information in multiple languages originating from different communities. The objective of the workshop is to bring together researchers and practitioners interested in the development of methods for analysing event-centric multilingual information.

We are interested in approaches for extracting, validating, contextualizing and interlinking of event-related information. We aim to discuss technologies addressing the use of knowledge graphs in conjunction with NLP methods and visual analytics aiming to analyse event-centric information in multiple languages as well as developing novel methods for user interaction with multilingual information.

Topics of Interest:

The topics of interest of CLEOPATRA’2021 include the aspects related to processing multilingual event-centric information along the entire processing pipeline, starting with information extraction, through enrichment and user interaction to event analytics:
• Event extraction, co-reference and linking
• Relation extraction and linking
• NLP methods and tools for low-resource languages
• Sentiment analysis
• Fact verification, especially in connection with events
• Fake news detection
• Knowledge graph population
• Event representation in knowledge graphs
• Vocabularies for events
• Image-text relations for event analysis
• Event-centric Question Answering
• User interaction with multilingual data
• Human computation methods for multilingual data
• Propagation of event-centric information
• Language-specific bias
• Use of knowledge graphs in event analytics
• Use of knowledge graphs in cross-lingual and cross-cultural analytics
• Visualization techniques for event analysis
• Case studies for cross-lingual / cross-cultural event-centric analytics

Submission Guidelines:

We welcome the following types of contributions.
• Short (up to 6 pages including references) and full (up to 15 pages including references) research papers
• Poster abstracts and system demonstrations should not exceed 4 pages

All submissions must be written in English and must be formatted according to the Springer LNCS proceedings style. Each submission will be reviewed by at least 3 members of the PC. Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the workshop.
