News The deadline for the paper submission has been extended to 17th January 2020!

Welcome to Sideways!

Nowadays Social media platforms represent freely-accessible information networks allowing registered and unregistered members to read, share and broadcast posts, different in format and size, referring to a potentially-unlimited range of topics, by also exploiting the immediateness of handy smart devices. This workshop wants to stress the vision of these powerful communication channels as social sensors, where each user reacts in real time to the underlying reality by providing her own interpretation of the reality that needs to be analysed, understood and interpreted. Technologies on this connectivity may also provide automatic or semi-automatic applications for information detection and integration, offering a sideway to the existing authoritative information media and the information reported by the surrounding community.

Call for papers


Nowadays, online social media platforms have become the most popular communication system all over the world. In fact, due to the accessibility and the public of these platforms, users tend to shift from traditional communication tools (such as traditional web sites) to these social services. For example, 68 percent of U.S. adults get news on social media in 2018, while in 2012, only 49 percent reported seeing news on social media. Billions of messages, in many different formats, are appearing daily in these services such as Twitter, Instagram, Facebook, etc. The authors of these messages share content about any aspect of their life (public or private), exchanging opinions on a variety of topics and creating and discussing a wide range of events.

Companies like Facebook, Twitter and Instagram have unlocked new ways for people to connect, curate, and consume and also see the surrounding reality. Social Media have changed and continue to change how we interact with the web - how content is distributed, discovered, and delivered. They provide inexpensive communication medium that allows anyone to quickly reach and interact with many other users, modifying their point of view and even their interpretation of the facts. Consequently, in these platforms anyone can publish content and anyone interested in the content can obtain it, representing a transformative revolution in our society. These aspects make Social Media services the most powerful sensor for any possible interpretation of reality, by also bringing into question the researchers in defining what reality means. The aim of this workshop is to ask researchers to enter into such view, by studying how Social Media can be used in a real-time scenario to detect events and their interpretations.

In light of this, we stress the importance of recognizing this real-time sensor role of Social Media and propose a research venue to discuss about it.
