The impact of fake news in the global economy, public health and even in the creation of panic in society has been extensively documented in the past few years with
countless examples. Thus, the high cost associated with the spread of fake news: the absence of control and verification of the information, which makes social media a fertile ground for the spread of unverified or false information. With this in mind, we
can affirm that the magnitude, diversity and substantial dangers of fake news and, in more general terms, the disinformation circulating on social media is becoming a reason of concern due to the potential social cost it may have in the near future. As a consequence,
the research community in the field of Natural Language Processing, has been focusing on the detection and intervention of fake news using techniques such as Machine Learning and Deep Learning, and taking into account: – Content-based features contain information
that can be extracted from the text, such as linguistic features. – Context-based features contain surrounding information such as user characteristics, social network propagation features, or users’ reactions to the information.

Thus, the objective of this workshop is to foster research both
at the theoretical as well as at the level of practical real-world applications of NLP technologies applied to misinformation mitigation. The workshop aims at bringing together researchers, developers and industries interested in the problem of mitigating
misinformation through NLP technologies. We will discuss recent trends and research projects, as well as developments and advances being made in the area of NLP to address the problem of misinformation from different perspectives.
