Dragomir Radev, a top NLP expert and Yale University computer professor, passed away at the age of 54, and Chinese students expressed their condolences.

On March 30, local time, Dragomir Radev, a professor at Yale University, a famous computer scientist, and a top expert in the fields of natural language processing and artificial intelligence, passed away.

He is a 2018 ACL Fellow, a 2015 ACM Fellow, a 2020 AAAS Fellow and a 2020 AAAI Fellow.

Top expert in the field of NLP

Dragomir Radev, born on August 7, 1968 in Sofia, Bulgaria, immigrated in 1991 U.S.

In 2017, Radev joined Yale University and became the A. Bartlett Giamatti Professor in the Department of Computer Science, focusing on natural language processing and information retrieval.

Prior to that, he served as a professor of computer science at the University of Michigan for 16 years.

To realize the infrastructure that allows computers and humans to interact in a smooth, natural way, Drago collaborates with partners across the Yale campus including the Yale School of Medicine, the Department of Linguistics, and the Wu Cai Neuroscience Institute Experts from various fields, including

Radev works in the areas of open domain question answering, multi-document summarization, and applications of NLP in bioinformatics, social network analysis, and political science.

In 1999, Radev received his PhD in Computer Science from Columbia University. His doctoral thesis broke into the field of natural language processing with pioneering research on multi-document text summarization.

After his PhD, Radev was a prolific researcher whose subsequent work was equally influential, starting with his work on LexRank widely cited papers, to recent papers in which he provides datasets, benchmarks, and evaluation metrics for abstracts.

Moreover, his projects are rich and ambitious. These projects include improving the processing of electronic health records, automated book summarization and programming humor into natural language processing systems.

# Along the way, he has worked on various types of abstracts including news, conversations, scientific articles and citation surveys. His research spans many areas beyond the abstract.

He works on graph-based methods for natural language processing, question answering systems, database interfaces, and language generation.

It is worth mentioning that he is the co-founder and co-organizer of NACLO (North American Computational Linguistics Olympiad). This is a difficult linguistics exam for high school students that takes part in an international competition every year with top-ranked contestants.

As the founder of NACLO, Radev and the Linguistic Society of America jointly received the Linguistics, Language and Public Award from the Linguistic Society of America in 2011. He is also a recipient of the Gosnell Prize (2006).

In 2015, he was awarded the Fellowship of the ACM Computer Society "in recognition of his contributions to natural language processing and computational linguistics."

He has had a huge impact on ACL and received the Distinguished Service Award in 2022 for his outstanding contributions to the field. He served as ACL Secretary from 2006 to 2015.

Radev has had a continuous record of service to ACL over the past 20 years, serving in various roles including ACL Secretary and NAACL Treasurer. The role of ACL secretary is all-encompassing and requires constant monitoring and maintenance.

Radev was an outstanding man who exemplified the qualities of kindness, generosity, intelligence and dedication in every aspect of his life.

Radev is also a highly sought after lecturer. More than 200 students have signed up for his AI course, which challenges students to build systems that can play two-player games, solve mazes and use neural networks to translate text.

At one point, he taught over 10,000 students in a massive open online course on natural language processing.

In addition to professional honors, Radev also cares deeply about students, and his care and guidance for Chinese and Chinese students and scholars is unparalleled.

And now, he is famous all over the world. He graduated with a Ph.D. while teaching at Michigan and Yale and serves as a professor at a world-class university.

deep condolences

The death of Dragomir Radev is a great sadness for the computer community.

Just now, ACL issued a message to express its deep condolences.

Jeffery Brock, dean of engineering and applied sciences at Yale University, sent an email to SEAS stating that Dragomir Radev has passed away. Please join me in offering my sincerest condolences to his family and to all those whose lives and careers benefited from Drago's creativity and spirit.

William Wang, assistant professor in the Department of Computer Science at UC Santa Barbara, also issued a message to express his deep condolences for the death of Dragomir Radev.

Yu Tao, assistant professor of the Department of Computer Science at the University of Hong Kong, posted, "In memory of my beloved doctoral supervisor Dragomir Radev."

Yunyao Li, director of machine learning at Apple Knowledge Platform,

Today is a sad day. I suddenly lost a dear mentor and friend. Dragomir Radev is a very smart and kind man. My first natural language processing course was taught by him. He was on my thesis committee. We've been working together and I've learned a lot from him. He will forever be missed.

Another student of Dragomir Radev said that

was deeply moved by the loss of an outstanding mentor. Friend and my doctoral advisor at the University of Michigan is deeply saddened. Professor Dragomir Radev's kindness and guidance have left a lasting mark on the lives of many.

Dong Yue, assistant professor of computer science and engineering at the University of California, Riverside, also expressed deep memories of his mentor.
