This paper presents a refinement of the probabilistic medical record linking algorithm. We introduced "close agreement" to account for typical errors in administrative variables used for record linkage. Linking data on early pregnancy determinants with data on late child outcomes was used as a case study. We analyzed whether the addition of close agreement resulted in a higher discriminating po...

In recent years, geological disposal of radioactive waste has focused on placement of highand intermediate-level wastes in mined underground caverns at depths of 500–800 m. Notwithstanding the billions of dollars spent to date on this approach, the difficulty of finding suitable sites and demonstrating to the public and regulators that a robust safety case can be developed has frustrated attemp...

Record linkage is a technique used to link records from one database with records from another database, making reference to the same individuals. Although it is normally used in database integration, it is also frequently applied in the context of data privacy. Distance-based record linkage permits linking records by their closeness. In this paper we propose a supervised approach for linking r...

Record linking is the task of detecting records in several databases that refer to the same entity. This task aims at exploring the relationship between entities, which normally lack common identifiers in heterogeneous datasets. When entities contain multiple relational records, linking them across datasets can be more accurate by treating the records as groups, which leads to group linking met...
