I am a Research Staff Member (Research Scientist) at IBM T. J. Watson Research Center working on NLP, Information Extraction and Machine Learning. My research focusses on making AI systems understand the meaning of natural language text. Most of my 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.
