The last step in a record linkage process - after records have been
compared and weight vectors have been calculated - is the
classification of record pairs into links, non-links, or
if this decision should be done by a human review, possible
The current version of Febrl contains the classical Fellegi
and Sunter classifier , as well as a flexible classifier
that allows various ways of calculation of a matching weight. They are
discussed in the following two sections.
Future version of Febrl will include improved
classification methods, based on sophisticated machine learning
techniques. In fact, one of the main aims of our future research
will be the development of better classification methods with the
ultimate aim to reduce - or even eliminate - the class of possible
links (and therefore reducing the time consuming clerical review
process). For more information please visit the Febrl web
site or contact the authors.
