Computer programs that detect online harassment could allow automatic interventions, e.g., providing advice to those involved, but we don\u2019t yet have machine learning algorithms that can handle the scale, the structure, and the rapidly changing nature of cyberbullying. Standard approaches for classification are hindered by the cost of labeling bullying examples and the need for social context to differentiate bullying from other less harmful behavior.<\/p>\n<\/div>\n
My group is developing machine learning algorithms that use weak supervision, where the input to the algorithm isn\u2019t whether each interaction is bullying, but general indicators of bullying, such as offensive language. The algorithms try to extrapolate from that using social media data, considering who\u2019s sending and receiving messages with the provided indicators, and the overall structure of the relationships in the data. The algorithms do collective, data-driven discovery of who is bullying, who\u2019s being bullied, and what additional vocabulary is indicative of bullying.<\/p>\n<\/div>\n
