Nanda Kambhatla

About me

manager, Statistical Text Analytics Group


Research lab: Watson Research Center (Yorktown)


Nanda Kambhatla was born in Hyderabad, India in 1969. He received a B.Tech degree with first class honors in 1990 in Computer Science and Engineering from the Institute of Technology, Benaras Hindu University, India, and a Ph.D degree in Computer Science and Engineering from the Oregon Graduate Institute of Science & Technology, Oregon, USA, in 1996.

Since 1996, Nanda has worked as a postdoctoral fellow under Prof. Simon Haykin at McMaster University, Canada and as a senior research scientist at WiseWire Corporation, Pittsburgh. He joined IBM's T.J.Watson Research Center in 1997 and worked on spoken dialog systems for call routing, telephony banking and stock trading, the universal interaction middleware architecture and a web based dialog system for helping people shop for thinkpads online.

Since 2000, Nanda has led a team working on Information Extraction and text mining. Since 2002, the team has achieved top tier results in successive Automatic Content Extraction (ACE) evaluations conducted by NIST for extracting entities, events and relations from text from multiple sources, in multiple languages and forms. The team has created a toolkit for information extraction that includes a tool for human annotation of documents, a trainer for building machine learning models and a fast, scalable decoder for extracting information from raw text using the trained models.

Currently, Nanda is the manager of the Statistical Text Analytics Group and co-chair of the NLP PIC at Watson. He is also leading the Language Exploitation Environment (LEE) subtask for the DARPA GALE project.

Nanda's research interests are focused on technology solutions for creating, storing, searching, and processing large volumes of unstructured data (text, audio, video, etc.) and specifically on applications of statistical learning algorithms to these tasks.
