Kishore Papineni

Also known as Kishore A. Papineni

Kishore Papineni is a computer scientist whose work includes BLEU, a metric for automatic evaluation of machine translation. He earned a PhD in electrical engineering at Rice University in 1995 and was named as an inventor on a 2001 patent for a task-oriented natural-language dialog manager. He coauthored BLEU in 2002 and the TIPS demonstration paper in 2003, and served as founding editor-in-chief of ACM Transactions on Speech and Language Processing from 2003 to 2007. He joined Yahoo Research as senior research director in 2006 and Google as senior research scientist in 2012, and coauthored feature-contrastive learning and generative masked language model research in 2021 and 2024 after BLEU received its 2018 Test-of-Time Paper award. As of October 2026, he leads Google's Coauthor team in work on cross-lingual, cross-modal information access.

Timeline

  1. 1995–2001

    A Rice PhD and dialogue patent

    He earns a PhD in electrical engineering at Rice University in 1995, with research in systems and control theory. A 2001 patent lists him as an inventor of a natural-language task-oriented dialog manager for speech-recognition systems.

  2. 2002

    The BLEU translation metric

    In 2002, he coauthors BLEU with Salim Roukos, Todd Ward and Wei-Jing Zhu, a metric for automatic evaluation of machine translation quality.

  3. 2003

    A translingual information system

    In 2003, he coauthors TIPS, a NAACL demonstration paper titled A Translingual Information Processing System.

  4. 2003–2007

    Founding editor-in-chief

    From 2003 to 2007, he serves as founding editor-in-chief of ACM Transactions on Speech and Language Processing.

  5. 2006–2012

    Yahoo and Google research roles

    In 2006, he joins Yahoo! Research as a senior research director and leads the machine-learning team. In 2012, he joins Google as a senior research scientist.

  6. 2018

    A Test-of-Time paper award

    In 2018, the BLEU paper receives a Test-of-Time Paper award in computational linguistics.

  7. 2021–2024

    Feature learning and masked language models

    In 2021, he coauthors Feature Contrastive Learning, which encourages models to be more sensitive to features with high contextual utility. In 2024, he coauthors a framework for generative masked language models that adapts T5 for iteratively-refined parallel decoding, achieving 2–3x speedup in machine translation with minimal sacrifice in quality.

  8. As of October 2026

    Leading Google's Coauthor team

    As of October 2026, he leads Google's Coauthor team, whose objective is cross-lingual, cross-modal access to dynamically organized information.

From the biography.

  1. 11% of AI doctorate holders from 2010 to 2016 founded or led a company or lab by 10 years after graduationIncludes Kishore Papineni. We estimate how often AI doctorate holders founded or led a company or lab by 10 years after graduation, how waiting times compare between founders and top jobs, and which universities trained the most.
  2. Google had the most people shaping AI every year from 2014 to 2025Includes Google. Our estimates of which organizations employed the most people shaping AI each year from 1955 to 2025, tracing the shift from university labs to companies.
  3. Google has the highest combined h-index among AI organizationsIncludes Google. We estimate that Google holds the highest combined h-index at 8,016, while universities account for 73% of the deduplicated total across AI organizations.
  4. 20% of people at companies who shape AI also hold a university role, led by Google and Stanford UniversityIncludes Google. We estimate that 539 of the 6,766 people with a known current organization (8%) hold both a university role and a company role, including 20% of people at companies and 13% of people at universities.
