## Research

Preslav Nakov works in the area of natural language processing and text mining. He has published over 300 peer-reviewed research papers. Preslav Nakov's early research was on lexical semantics and text mining. He published influential papers on biomedical text mining, most prominently on methods to identify citation sentences in biomedical papers. He is though most well-known for his research on fake news detection, such as his work on predicting the factuality and bias of news sources, as well as for his research on the automatic detection of offensive language. Nakov also previously led the organisation of a popular evaluation campaign on sentiment analysis systems as part of SemEval between the years of 2015 and 2017. He currently coordinates the Tanbih News Aggregator project, a large project with partners at the Qatar Computing Research Institute and the MIT Computer Science and Artificial Intelligence Laboratory, which aims to uncover stance, bias and propaganda in news.
