Towards the use of OWA operators for record linkage

Record linkage is used to establish links between those records that while belonging to two different files correspond to the same individual. Classical approaches assume that the two files contain some common variables, that are the ones used to link the records. Recently, we introduced a new approach to link records among files when such common variables are not available. In this approach, reidentification is based on the so-called structural information. In this paper we study the use of OWA operators for extracting such structural information and, thus, allowing re-identification.
