Joseph Amadee Goguen (/ˈɡoʊɡən/ GOH-gən; June 28, 1941 – July 3, 2006) was an American computer scientist. He was professor of Computer Science at the University of California and University of Oxford, and held research positions at IBM and SRI International.

In the 1960s, along with

fuzzy set theory.[1][2]
In the 1970s Goguen's work was one of the earliest approaches to the algebraic characterisation of
Goguen categories are named after him.[9][10]

He was married to Ryoko Amadee Goguen, who is a composer, pianist, and vocalist.[11]

Education and academic career

Goguen received his

Lotfi Zadeh.[2]

He taught at

IBM Watson Research Center, where he organised the "ADJ" group.[12] He also visited the University of Edinburgh in Scotland on three Senior Visiting Fellowships.[5]

From 1979 to 1988, Goguen worked at SRI International in Menlo Park, California. From 1988 to 1996, he was a professor at the Oxford University Computing Laboratory (now the Department of Computer Science, University of Oxford) in England and a Fellow at St Anne's College, Oxford.[2] In 1996 he became professor of Computer Science at the University of California, San Diego.[2]

Research areas

Goguen's research interests included category theory (a branch of mathematics), software engineering, fuzzy logic, algebraic semantics, user interface design, algebraic semiotics, and the social and ethical aspects of science and technology. In the preface to a book dedicated to Goguen, Futatsugi, Jouannaud and Meseguer stated that Goguen's work changed the way we think about concepts such as data types, programming languages and software specification.[14]

In a review of Goguen's work on fuzzy sets Radim Belohlavek wrote that In the early stages of the development of fuzzy systems, Goguen made profound contributions with lasting influence.[1]

Lotfi Zadeh viewed Goguen's 1968 approach to "The Logic of Inexact Concepts" as seminal in the field of fuzzy logic.[2] Goguen's PhD dissertation "Categories of fuzzy sets"[15] was the first work to apply category theory to fuzzy logic, and led to Goguen categories being named after him.[9][10]

Goguen's research in the 1970s was one of the earliest approaches to the characterisation of computational automata from a categorical perspective.[3] Goguen's research with Thatcher, Wagner and Wright (also in the 1970s) was one of the earliest works to formalise the algebraic basis for data abstraction.[4]

In the early 1990s Goguen and Rod Burstall developed the theory of institutions, a category-theoretic description of logical systems in computer science.[16] Institution theory impacted the development of universal logic and became one of its most studied aspects.[17] The term "Carnapian Goguenism" is used to refer to the application of institutions to ontologies.[18]

Goguen also studied the philosophy of computation and information,

theorem proving), and relational and functional programming. He wrote a retrospective of his work and its context, Tossing Algebraic Flowers Down the Great Divide.[19]
