Researcher

Tong-Haing Fin

Tong-Haing Fin is a computing researcher whose work spans distributed collaboration, cross-language retrieval and IBM Watson's question-answering system. His paper with Takashi Masuda appears in proceedings for the 14th IBM Computer Science Symposium, held in October 1980 and published by Springer in 1982; he also coauthored a shared-pointer design for distributed meetings in 1990. IBM-assigned patents name him as an inventor on Internet page sharing and cross-language document search, and he coauthored a 2004 paper on glossary-based technical-support retrieval. In 2010, he was among IBM's researchers and engineers responsible for Watson and DeepQA; he coauthored an IBM Research report on building Watson in 2013 and was on the team when it received AAAI's Feigenbaum Prize.

Timeline

  1. 1980–1982

    Program behavior and its models

    The 14th IBM Computer Science Symposium takes place in October 1980, and its Springer proceedings are published in 1982. They include “Program behavior and its models,” a paper he coauthors with Takashi Masuda.

  2. 1990

    A telepointing tool

    In 1990, he coauthors “A telepointing tool for distributed meeting systems” with Amane Nakajima. The tool proposes a loosely coupled shared pointer that gives local operations priority over remote telepointing.

  3. 1996–2001

    Internet web page sharing

    In 1996, he files an IBM patent for Internet web-page sharing with Tetsunosuke Fujisaki, Makoto Kobayashi and Masahide Shinozaki; the US patent is granted in 2001.

  4. 2002–2007

    Multilingual document search

    In 2002, he co-invents an IBM search method that accepts a keyword query in one supported language and returns matching documents in multiple languages. The US patent is granted in 2007.

  5. 2004

    Glossary-based support search

    In 2004, he coauthors “Glossary extraction and utilization in the information search and delivery system for IBM Technical Support.”

  6. 2010–2013

    Watson and DeepQA

    In 2010, he is among the IBM team members responsible for Watson and the DeepQA architecture. Watson is designed to compete with human Jeopardy! champions in real time, and DeepQA combines more than 100 techniques for natural-language analysis, evidence gathering and answer ranking. In 2013, he coauthors an IBM Research report, “Tools and Methods for Building Watson,” with Eric Brown, Eddie Epstein and J. William Murdock.

  7. 2013

    IBM Watson Team member

    In 2013, the IBM Watson Team wins AAAI's Feigenbaum Prize for showing that a synthesis of symbolic knowledge representation, natural language understanding and statistical machine learning can achieve human-level performance in real-time factual question answering. Fin is one of its members.

  1. 23% of people shaping AI who left a university for a company later returned to a universityIncludes IBM. We estimate that 468 of the 2,011 people shaping AI who left a university for a company (23%) later returned to a university after a median of 5 years, and 163 of 829 (20%) made the reverse round trip.
  2. Google alumni have founded or led 133 other organizations, more than any other AI labIncludes IBM. We estimate that alumni of 17 major AI labs went on to found or lead 350 other organizations, including 226 they founded, and we trace 472 career moves directly between 23 labs since 2010.
  3. Universities keep AI researchers for a median of 6 years, compared with 2 years at frontier labsIncludes IBM. Across 15,811 dated work stays (6,529 people), median role tenure runs from 6 years at universities to 2 years at frontier labs. We compare all five organization types, starting decades from the 1970s to the 2020s, and the organizations that keep people longest.
  4. People shaping AI work at a median of 3 organizations over a career: 3 for university starters and institute and lab starters, versus 2 for company startersIncludes IBM. Across 6,853 people shaping AI with a dated work role, we estimate a median of 3 parent organizations over a career (mean 3.6), comparing role groups, starting sectors and starting decades from the 1950s to 2020–2026.
