Professor Matthew Roughan

Abstract Algebras and the Record Linkage Problem

Record Linkage is the process of finding matching records in one or
more databases when they lack a common key. When the data contain errors,
a common approach is modelling the probability of pairwise matches, and
then choosing only the high-probability links. However, that ignores the
larger scale structure of the problem which may be important for some
problems, particularly those involving many datasets. In this talk, I will
discuss some initial ideas related to using the entire graph of matching
data, in particular the use of algebraic operators from group theory on
the problem.

Biography of Prof. Matthew Roughan

Prof. Matthew Roughan has worked in the School of Mathematical Sciences at
the University of Adelaide since 2004. His research interests range from
stochastic modelling to measurement and management of networks like the
Internet, but more recently have been branching out into other types of
network.
