In particular, the general theme of the CLEOPATRA workshop – event-centric multilingual analytics – represents an interdisciplinary challenge for analysing vast amounts of event-centric textual and visual information in multiple languages across different communities. To this end, CLEOPATRA is the only forum which brings together researchers from a variety of strongly related areas dealing with understanding cross-cultural and cross-lingual information propagation, cross-lingual news reporting with bias as well as extraction and alignment of event-centric information. Furthermore, the multidisciplinary nature of the workshop will allow researchers from several distinct (though highly related) sub-communities of ESWC to interact with respect to early ideas, work in progress and mature research results.

The goal of the interdisciplinary CLEOPATRA workshop is bringing together researchers and practitioners from the fields of Semantic Web, the Web, NLP, IR, Human Computation, Visual Analytics and Digital Humanities to discuss and evaluate methods and solutions for effective and efficient analytics of event-centric multilingual information spread across heterogeneous sources to deliver analytical results in the way meaningful to the users, helping the users to cross the language barrier and better understand event representations in other languages and their context.

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. We want to facilitate a discussion around how to facilitate event-centric cross-lingual analytics and cross-cultural studies.

Workshop topics and themes: CLEOPATRA’2020 will gather novel works from the fields of Semantic Web, NLP, Information Retrieval, Visual Analytics and Human Computation in particular in the context of processing of multilingual event-centric data, knowledge graph population and applications in the field of Digital Humanities and Web Science. CLEOPATRA’2020 will equally consider both novel scientific methods and techniques for extraction and enrichment of multilingual data as well as the application perspective, such as the innovative use of tools and methods for providing rich interaction with extracted semantic information. We will seek application-oriented, as well as more theoretical papers and position papers.

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
