• Andrew McCallum Professor

    The main goal of my research is to dramatically increase our ability to mine actionable knowledge from unstructured text. I am especially interested in information extraction from the Web, understanding the connections between people and between organizations, expert finding, social network analysis, and mining the scientific literature & community. Toward this end my group develops and employs various methods in statistical machine learning, natural language processing, information retrieval and data mining---tending toward probabilistic approaches and graphical models.

PhD Students

  • Nishant Yadav PhD, started 2017

    I am broadly interested in machine learning  and natural language processing. A bit more specifically, I am interested in methods for learning representation of entities, structured prediction models and clustering.

  • Sheshera Mysore PhD, started 2018

    My current interests involve the development of resources and methods in interactive machine learning and natural language processing to facilitate greater user control and transparency in search and recommendation.

  • Neha Kennard PhD, started 2018

    My research interests are in Natural Language Processing. At the moment, I am working on understanding document-level discourse structure, and applications of this research to the peer review domain.

  • Andrew Drozdov PhD, started 2018

    My current research interests are in automatic structure discovery, instance-based learning, and text generation.

  • Shib Sankar Dasgupta PhD, started 2019

    I am interested in time-aware representation learning for both text and KBs. Currently, I working with box embeddings to model relational data.

  • Rico Angell PhD, started 2019

    I am interested in machine learning, natural language processing, learning with limited data, and information extraction.

  • Dhruvesh Patel PhD, started 2021

    I am broadly interested in machine learning for NLP with special focus on interpretable and instructable methods that can learn from raw data while being guided/instructed by structured external knowledge/constraints.

  • Wenlong Zhao PhD, started 2021

    My current research involves structured prediction and representation learning for natural language. I also work on efficient deep learning, computer vision, and interdisciplinary applications of algorithms, such as, AI for sustainability.

  • Benjamin Rozonoyer PhD, started 2022

    I am interested in theoretical machine learning and natural language processing, including semantic parsing and information extraction.

  • Dhruv Agarwal PhD, started 2022

    My broad research interest is in machine learning for natural language processing and its application in tasks that require complex, multi-step reasoning. My current focus is on interactive machine learning to probabilistically incorporate human-provided constraints and feedback.
