Researcher

Roberto Busa

Roberto Busa was an Italian Jesuit scholar who applied computers to linguistic analysis through the Index Thomisticus, a concordance of Thomas Aquinas's writings. He conceived the project in 1946, gained IBM's support in 1949, and completed its 56-volume print edition by 1980. His career included a computing center in Gallarate, university teaching in artificial intelligence and robotics, the Index's CD-ROM edition in 1992, and the first Roberto Busa Prize in 1998. He donated his library and working papers in 2010 and died in 2011.

  1. More people shaping AI studied at Massachusetts Institute of Technology than at any other institutionIncludes Polytechnic University of Milan. We estimate where the people shaping AI studied and where their careers led. Massachusetts Institute of Technology leads with 467 former students, including 291 recorded doctorates.
  2. The company share of AI researchers’ top papers was 31% in 2020–2024 and 8% in 1970–1974Includes Polytechnic University of Milan. We estimate where the people shaping AI worked when their most-cited papers appeared: the company share was 31% in 2020–2024 and 8% in 1970–1974, and Google led all organizations in 2020–2024.
  3. 11% of AI doctorate holders from 2010 to 2016 founded or led a company or lab by 10 years after graduationIncludes Polytechnic University of Milan. 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.
  4. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other universityIncludes Polytechnic University of Milan. The Massachusetts Institute of Technology trained or employed 44 of the 187 AI major-prize winners, more than any other university. We compare doctorate and 5+ year employment links, career timing and current workplaces for 187 major-prize and 1,111 best-paper winners.
