US-based startup Preamble collaborated with 50 Omdena AI engineers and data scientists to develop a cost-effective solution to detect harmful situations in online video challenges. Using computer vision the team was ablo to detect if a video is harmful or not.
The results from this project are intended as a baseline to help Preamble build solutions for safer online platforms.
Children are more susceptible to acting impulsively and participating in online internet challenges. Internet challenges can encourage kids to replicate unsafe behaviors to increase user engagement and materiality on social media. Some of these outrageous challenges have led to severe bodily harm and even death. To protect children from these types of dangerous ideas and peer pressure, we are building a model to filter out this content.

Some prior internet challenges that are dangerous to participants and especially children:
The team divided several tasks across contributors according to their expertise in the following process:
The bulk of the teamwork was concentrated on data collection and labeling. The team developed scripts to facilitate video and metadata retrieval from social media platforms. Specifically, existing python libraries were used to download videos from YouTube, Vk, and TikTok. Through this process, the team manually collected more than 240 challenge videos.

After a manual and partly automated labeling process of images and challenges as harmful, ambiguous, or not harmful, the team tested several computer vision models. As an outcome of this eight weeks project, the best-fit model was able to detect if a video is harmful or not using the labeled data set. The following steps will be to expand the model performance and applicability to a broader set of conditions.
