This paper presents a new two-step approach for record linkage, focusing on the creation of high-quality training data in first step. The employs unsupervised random forest model as similarity measure to produce score vector matching. Three constructions were proposed select non-match pairs data, with both balanced (symmetry) and imbalanced (asymmetry) distributions tested. top construction was...

Assuming that there are two sources (e.g. les), which consist of records with diierent informations about some units like people. We want to fusion the information (data) that belong to the same units. Very often in practice no identiication numbers | like the Social Security Number SSN | are available at both les, that's why there is some uncertainity, which records belong together. Anyway, we...

We study shedding in the setting of data linkage dynamics, a simple model of computation that bears on the use of dynamic data structures in programming. Shedding is complementary to garbage collection. With shedding, each time a link to a data object is updated by a program, it is determined whether or not the link will possibly be used once again by the program, and if not the link is automat...

abstract background: autosomal dominant polycystic kidney disease (adpkd) is an inherited disorder with genetic heterogeneity. up to three loci are involved in this disease, pkdi on chromosome 16p13.3, pkd2 on 4q21, and a third locus of unknown location. methods: here we report the first molecular genetic study of adpkd and the existence oflocus heterogeneity for adpkd in the iranian population...
