Record linkage also known as data matching, entity resolution, and many other terms is the task of finding records in a data set that refer to the same entity across different data sources e. Record linkage is necessary when joining different data sets based on entities that may or may not share a common identifier e. A data set that has undergone RL-oriented reconciliation may be referred to as being cross-linked. Record linkage is referred to as data linkage in many jurisdictions, but the two are the same process. However, many other terms are used for this process. Unfortunately, this profusion of terminology has led to few cross-references between these research communities. Computer scientists often refer to it as "data matching" or as the "object identity problem".

This book helps practitioners gain a deeper understanding, at an applied level, of the issues involved in improving data quality through editing, imputation, and record linkage. The first part of the book deals with methods and models. Here, we focus on the Fellegi-Holt edit-imputation model, the Little-Rubin multiple-imputation scheme, and the Fellegi-Sunter record linkage model. Brief examples are included to show how these techniques work. In the second part of the book, the authors present real-world case studies in which one or more of these techniques are used. They cover a wide variety of application areas. These include mortgage guarantee insurance, medical, biomedical, highway safety, and social insurance as well as the construction of list frames and administrative lists.

Record linkage

Прямо перед ним над деревьями возвышалось Аюнтамьенто - старинное здание ратуши, которое окружали три акра бело-голубой мозаики азульехо. Его арабские шпили и резной фасад создавали впечатление скорее дворца - как и было задумано, - чем общественного учреждения.

Возбужденный, Беккер ускорил шаги в поисках телефона. По другой стороне улицы, оставаясь невидимым, шел человек в очках в тонкой металлической оправе. ГЛАВА 27 Тени в зале шифровалки начали удлиняться и терять четкость. Автоматическое освещение постепенно становилось ярче. Сьюзан по-прежнему молча сидела за компьютером, ожидая вестей от Следопыта. Поиск занял больше времени, чем она рассчитывала. Мысли ее мешались: она тосковала по Дэвиду и страстно желала, чтобы Грег Хейл отправился домой.
