Keith van Rijsbergen was born in Holland in He was educated in Holland, Indonesia, Namibia and Australia. He took a degree in mathematics at the University of Western Australia.
As a graduate he spent two years tutoring in mathematics while studying computer science. In he completed a Ph. After almost three years of lecturing in information retrieval and artificial intelligence at Monash University he returned to the Cambridge Computer Laboratory to hold a Royal Society Information Research Fellowship. In he was appointed to the chair of computer science at University College Dublin; from there he moved in to the Glasgow University where he is now.
Since about his research has been devoted to information retrieval, covering both theoretical and experimental aspects. He has specified several theoretical models for IR and seen some of them from the specification and prototype stage through to production. His current research is concerned with the design of appropriate logics to model the flow of information. In he was appointed Editor-in-Chief of The Computer Journal , an appointment he held until He has served as a programme committee member and editorial board member of the major IR conferences and journals.
He is the author of a well-known book Information Retrieval, Butterworths, In , together with Crestani and Lalmas,he published a book entitled "Information Retrieval: Uncertainty and Logics". Some of his old papers can be accessed here.
The geometry of information retrieval
This chapter has been included because I think this is one of the most interesting and active areas of research in information retrieval. There are still many problems to be solved so I hope that this particular chapter will be of some help to those who want to advance the state of knowledge in this area. All the other chapters have been updated by including some of the more recent work on the topics covered. I am grateful to the University of Cambridge Computer Laboratory for providing me with the facilities for carrying out the work. Some of the chapters, particular chapter 6 this became chapter 7 in the second edition , make simple use of a little advanced mathematics. However, the necessary mathematical tools can be easily mastered from numerous mathematical texts that now exist and, in any case, references have been given where the mathematics occur. I had to face the problem of balancing clarity of exposition with density of references.
