About him: 
Avi is a Research Scientist in the Information Extraction and NLP group at IBM Research AI. He is also the Chair of the NLP professional community of IBM. His research focusses on making AI systems understand the meaning of natural language text. Most of his work has been on making sense of large unstructured web data applying machine learning algorithms: Extracting entities (names of persons, organizations, etc.), resolving them to big knowledge-bases (like Wikipedia) and extracting relationships between the entities.

Here's a recent article about his research on Entity Linking.

Avi completed 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.
