On the Ephemerality of Web Media
A lot of our research and development activities rely on large collections of web media content sourced from social media platforms, such as YouTube and Twitter, and then manually curated and annotated by our researchers with the purpose of creating “ground truth” datasets. This helps us train machine learning models on specific tasks and then benchmark those models along with competing approaches in order to select the best method per case.
