Our Impact

Combating disinformation and abuse in social media

Sheffield’s big data analytics has probed the veracity, sentiment, and sharing patterns of social media posts and exposed the ways social media can be used and abused to shape opinions about significant political events, such as elections or the Brexit referendum. The methods and findings have been used to promote truth in public discourse, underpinning UK and international policy responses to misinformation and the misuse of social media in relation to various issues.

Automatic speech recognition

Automatic Speech Recognition (ASR) for conversational speech is a challenging research problem, particularly in the context of adverse acoustic conditions such as over the telephone or in multi-party meetings. Researchers in the department have developed, with industry, state-of-the-art ASR tools.

Machine translation

Machine translation (MT) is inexpensive, fast, and accessible, but it lacks the reliability of human translators. Sheffield research on quality estimation (QE) in MT has enabled the identification of the likelihood of error, allowing MT to be used with greater confidence and underpinning impacts for multiple organisations.
