1st International Workshop on Knowledge Graphs for Online Discourse Analysis (KnOD 2021)

Collocated with The Web Conference 2021, 19-23 April 2021, Ljubljana, Slovenia

The proceedings are now available through CEUR-WS.org

Expressing opinions and interacting with others on the Web has led to the production of an abundance of online discourse data, such as claims and viewpoints on controversial topics, their sources and contexts (events, entities). This data constitutes a valuable source of insights for studies into misinformation spread, bias reinforcement, echo chambers or political agenda setting.

While knowledge graphs promise to provide the key to a Web of structured information, they are mainly focused on facts without keeping track of the diversity, connection or temporal evolution of online discourse
data. As opposed to facts, claims are inherently more complex. Their interpretation strongly depends on the context and a variety of intentional or unintended meanings, where terminology and conceptual understandings strongly diverge across communities from computational social science, to argumentation mining, factchecking, or viewpoint/stance detection.

This workshop aims at strengthening the relations between these communities, providing a forum for shared works on the modeling, extraction and analysis of discourse on the Web. It will address the need for a shared understanding and structured knowledge about discourse data in order to enable machine-interpretation, discoverability and reuse, in support of scientific or journalistic studies into the analysis of societal debates on the Web.

Beyond research into information and knowledge extraction, data consolidation and modeling for KG building, the workshop targets communities focusing on the analysis of online discourse, relying on methods from machine learning, natural language processing and Web data mining. These include communities on:

  • discourse analysis
  • social web mining
  • argumentation mining
  • computational fact-checking
  • mis- and dis-information spread
  • bias and controversy detection and analysis
  • stance / viewpoint detection and representation
  • opinion mining
  • rumour, propaganda and hate-speech detection

KnOD provides a meeting point for these related but distinct communities that address similar or closely related questions from different perspectives and in different fields, using different models and definitions of the main notions of interest. Often these communities apply their research in particular domains, such as scientific publishing, medicine, journalism or social science. Therefore, the workshop is particularly interested in works that apply an interdisciplinary approach, such as works on computational social sciences or computational journalism.

Topics of interest include, but are not limited to, the following: 

  • Ontologies and data models for online discourse data
  • Reuse and extension of existing models such as schema.org
    and Wikidata
  • Knowledge graphs and knowledge extraction techniques in the context of online discourse
  • Computational fact-checking / truth discovery
  • Bias and controversy detection and analysis
  • Stance and viewpoint discovery
  • Rumour, propaganda and hate-speech detection
  • Intent discovery for claims
  • Interpretability and explainability of online discourse analysis methods
  • Integration, aggregation, linking and enrichment of discourse
  • Semantic and exploratory search of online discourse data
  • Argumentation and reasoning over online discourse
  • Recommender systems for discourse data
  • Quality, uncertainty, provenance, and trust of discourse data
  • Benchmarks and training data for extraction, verification or
    linking of discourse data
  • Use-cases, applications and cross-community interfaces
