About him: 
Dr. Avi Sil is a Principal Research Scientist and a Team Lead in the Multilingual NLP group at IBM Research AI. He leads the Question Answering and Information Retrieval team (comprising of Machine Learning scientists and engineers) and is one of the creators of the GAAMA system. His team works on cutting edge research on industry scale NLP and Deep Learning algorithms.
He is also the Chair of the NLP professional community of IBM.

His research also includes  Information Extraction: entity recognition and linking and relation extraction. He co-leads the TAC KBP track for Entity Discovery and Linking (EDL) along with Dr. Heng Ji. He is a senior program committee member for major Computational Linguistics conferences including being an Area Chair several times. His entity linking system has been the top system several years on TAC KBP evaluations by NIST. He has more than 12 US patents filed all in the area of Artificial Intelligence and it's applications in various spheres.

Avi finished his PhD in Computer Science under the supervision of his thesis advisor Alexander Yates. He also worked on Temporal Information Extraction in the Machine Learning Group at Microsoft Research, Redmond managed by Chris Burges and John Platt. His mentor was Silviu Cucerzan.
