C J Van Rijsbergen

Also known as Keith van Rijsbergen

C J Van Rijsbergen is a computer scientist whose research developed theoretical models for information retrieval. He completed a computer-science PhD at Cambridge in 1972, taught artificial intelligence at Monash, and led computer science departments in Dublin and Glasgow. At Glasgow, he founded the Information Retrieval Group; his books explored probabilistic, logical, geometric and quantum approaches to retrieval. He received the Tony Kent Strix Award in 2004 and the Gerard Salton Award in 2006. As of October 2026, he is an Honorary Senior Research Fellow at Glasgow and has retired from the university.

Timeline

  1. 1943–1972

    Mathematics and computer science

    Born in the Netherlands in 1943, he earns a mathematics degree at the University of Western Australia and completes a computer-science PhD at Cambridge in 1972.

  2. 1973–1979

    Teaching at Monash and Cambridge

    From 1973 to 1975, he lectures in information retrieval and artificial intelligence at Monash University. He holds a Royal Society Information Research Fellowship at the Cambridge Computer Laboratory and King’s College from 1975 to 1979; the 1979 second edition of Information Retrieval adds a chapter on probabilistic retrieval.

  3. 1980–1986

    Professor at Dublin and Glasgow

    He becomes professor and head of the Computer Science Department at University College Dublin in 1980. In 1986, he moves to Glasgow as professor in the Department of Computing Science and head of department.

  4. 1986

    The Glasgow Information Retrieval Group

    He founds the Glasgow Information Retrieval Group at the University of Glasgow in 1986. His research develops theoretical models for information retrieval, some of which he follows from prototype to production.

  5. 1993–2000

    Editor of The Computer Journal

    In 1993, he becomes editor-in-chief of The Computer Journal and holds the post until 2000.

  6. 1999

    Information Retrieval: Uncertainty and Logics

    In 1999, he publishes Information Retrieval: Uncertainty and Logics with Crestani and Lalmas.

  7. 2004–2006

    The Geometry of Information Retrieval

    He publishes The Geometry of Information Retrieval in 2004, presenting logical, probabilistic and vector-space models within a quantum-mechanical framework. In 2004, he receives the Tony Kent Strix Award; in 2006, he receives the Gerard Salton Award with an acceptance lecture titled “Quantum haystacks.”

  8. As of October 2026

    Honorary Senior Research Fellow

    As of October 2026, he is an Honorary Senior Research Fellow in the School of Computing Science at the University of Glasgow and has retired from the university.

  1. The company share of AI researchers’ top papers rose from 2% to 32%Includes University of Glasgow. We estimate where leading AI researchers worked when their most-cited papers appeared. The company share rose from 2% in 1975–1979 to 32% in 2020–2024.
  2. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes University of Cambridge. Our estimates of where the people shaping AI studied and where their careers led, from education records in cited biographies.
  3. Stanford University trained or employed 26 of the 108 AI major-prize winners, more than any other universityIncludes University of Cambridge. Stanford University trained or employed 26 of the 108 AI major-prize winners, more than any other university. We compare doctorate and employment links for major-prize and best-paper winners.
  4. 44% of AI career moves go from one university to anotherIncludes University of Cambridge. We estimate how 13,335 AI career moves link universities, companies, labs and government research centers, with net flows and the most common paths.
