    ROSNUB

    Jan 2022 - In progress

    ROSNUB (Project ID: 2018/00578/037) is a Marie Sklodowska-Curie Actions (MSCA) COFUND CONEX-Plus Project ( PI: Mohammad Hajarian). Reputation Metrics and Methods for Gamifying and Regulating Online Social Network Users’ Behaviors (ROSNUB) Project aim to address the problems online social media can cause in today’s human life. Nowadays, in online social networks, users are exposed to fake news, misinformation, online hostility, and misogyny talks generated by other users. In this situation, users might have less regulated emotions, accept extreme behaviors, and misperceive each other. These problems can start from social media and affect people’s mental and physical health in real life. Study results show that more than half of young social network users have experienced cyber aggression resulting in emotions such as depression, suicide, and embarrassment in their life. Incel movement is an excellent example of transforming hostility from online social networks to the real world. To tackle the mentioned problems, social media users’ behavior should be regulated. While legal solutions might help, they are not encouraging, and current social media ecosystems have been built on a foundation that encourages users to engage in such activities to gain more attention or, in other words, likes. Although a good number of studies have been conducted on these mentioned problems in social networks, all are about detecting such problems, and software engineering approaches for preventing them have not been investigated. This is very important because prevention is always a better solution than detection. As a result, this project investigates algorithms and frameworks to regulate social network users’ behavior joyfully in a personalized way and from the software engineering perspective to increase citizens’ mental and physical health and wellbeing.

    Datasets
    • SNEFL dataset is the first social network dataset with users' fuzzy like data which can be used for different social media studies, especially on INCELs. Corresponding article: https://link.springer.com/article/10.1007/s11042-019-08057-3 Download SNEFL dataset
    • Incel dataset data has been collected from Facebook and Twitter. We have collected 1048576 tweets from Twitter and 22058 Facebook posts. After preprocessing the collected data and removing unnecessary data and female users (because incels are male users), we had 511367 tweets and 9146 Facebook comments ready for the experiment. - Corresponding article: https://ieeexplore.ieee.org/document/9443027/ Download misogyny and incel comments dataset
