Semantics for Online Misinformation Detection, Monitoring, and Prediction

Workshop at ISWC 2020


The workshop proceedings has been published as part of the Advances in Semantics and Linked Data: Joint Workshop Proceedings from ISWC 2020, CEUR Volume 2722.

While the submission deadline expired, and given that this workshop and the main ISWC 2020 conference are now virtual events, we are happy to continue receiving new submissions until September 15th.


Digital misinformation is becoming pervasive in all online media to the extent that it has been listed by the World Economic Forum as one of the main threats to our society, by generating various technological and geopolitical risks ranging from terrorism to cyber attacks and the failure of global governance. In particular, there is evidence that misinformation has been affecting our perceptions in critical domains, such as health, politics, foreign policy, economy, and environment. Indeed, disinformation was found to pose high risks to society, by accelerating extremism, hysteria, and herding behaviour.

In spite of the rising addiction to rapid consumption of online news information, people and current technologies are yet to adapt to the age of misinformation. As a recent European Parliament report states, there is an urgent need to develop a new generation of content verification and misinformation analysis and tracking tools.

Some technologies have been developed to help validating different types of content (images, videos, bot accounts, news sources, reviews, etc.). Examples include NewsGuard, B.S.Detector, ClaimBuster,, and Others focused on developing techniques for automatically identifying false news, rumour posts, disputed arguments, measuring posts’ credibility, validating specific claims, or tracking the spread of disinformation. These technologies often use standard machine learning techniques, with little to no use of semantic techniques and representations.

Although disinformation is a common problem in media, it is exacerbated in digital social media due to the speed and ease with which content spreads. The social web enables people to spread information rapidly without confirmation of truth, and to paraphrase this information to fit their preconceptions, goals, and beliefs. This phenomenon is affecting society at all levels, including citizens, communities, journalists, and policymakers. Recent studies showed that false news spread far more virally than real news; sometimes thousands of times more. As a result, social media platforms have been put under heavy criticism and pressure to tackle the spread of misinformation, disinformation, and “fake news” on their platforms. However, these platforms are yet to offer adequate socio-technical solutions to this problem, and are unlikely to do so for various economic, technical, and ethical reasons.

On another front, more than 188 independent fact-checking groups and organisations emerged online in over 60 countries over the past decade, with an increase of 26% in the last year alone, and 61 of them are in Europe. These organisations provide independent professional fact checking to the public on various current news and information (e.g. elections, coronavirus), and many of them publish their fact checks using the ClaimReview semantic standard. However, simply publishing corrective information by fact checkers is often regarded as insufficient for changing misinformed beliefs and opinions.

To this end, semantics could offer major contributions to these efforts, in detecting misinformation content, monitoring its spread and impact, predicting its evolution, identifying misinforming sources, and locating relevant fact checking articles, relying on background knowledge graphs with adequate references such as Wikidata. Misinformation is a major societal challenge, and it is time for the Semantic Web researchers and practitioners to join their efforts to tackle this challenge.
