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

Collocated with TheWebConf (WWW) 2021
April 19 - 23, Ljubljana (Slovenia)


- Summary -

Expressing opinions and interacting with others on the Web has led to the availability of an abundance of online discourse data, such as claims and viewpoints on controversial topics, their sources and contexts (related events or entities). Discourse data constitutes a valuable source of insights for studies into misinformation spread, bias reinforcement, echo chambers or political agenda setting and is crucial as training/testing data for various NLP tasks. While knowledge graphs (KGs) 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, fact-checking, or viewpoint/stance detection.

This workshop aims at providing a forum for shared works on the modeling, extraction and analysis of discourse on the Web,  strengthening the relations between the fields of natural language processing (NLP,, computational linguistics, semantic web, knowledge graphs, argument mining and modeling, social sciences/communication studies, web science and computational social sciences. 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.
