Aim and Scope:

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 2020 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
* 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) and full (up to 15 pages) research papers
