Biography

Dr. Nakov leads the Tanbih mega-project (http://tanbih.qcri.org), developed in collaboration with MIT. The project's aim is to build a news aggregator that limits the effect of fake news, propaganda and media bias by helping users step out of their bubble and achieve a healthy news diet. He is also the lead-PI of a QCRI-MIT collaboration project on Arabic Speech and Language Processing for Cross-Language Information Search and Fact Verification (co-PI, 2016-2018; Lead-PI, 2018-present), and he was a co-PI of another QCRI-MIT collaboration project on Speech and Language Processing for Arabic (2013-2016).

Dr. Nakov is Secretary of ACL SIGLEX and also a Secretary of ACL SIGSLAV. He is member of the editorial board of Transactions of the Association for Computational Linguistics (TACL), Computer Speech and Language (CSL), Natural Language Engineerng (NLE), AI Communications, and Frontiers in AI journals. 

Dr. Nakov co-authored a Morgan & Claypool book on Semantic Relations between Nominals, two books on computer algorithms, and many research papers in top-tier conferences and journals. He received the Young Researcher Award at RANLP'2011. He was also the first to receive the Bulgarian President's John Atanasoff award, named after the inventor of the first automatic electronic digital computer.

Dr. Nakov's research was featured in over 100 news outlets, including Forbes, Boston Globe, Aljazeera, MIT Technology Review, Science Daily, Popular Science, Fast Company, The Register, WIRED, and Engadget, among others.
