Improving Record Linkage Through Pedigrees
Record linkage, in a genealogical context, is the process of identifying individuals from multiple sources which refer to the same real-world entity. Current solutions focus on the individuals in question and on complex rules developed by human experts. Genealogical databases are highly-structured …

Temporal Graph Record Linkage and k-Safe Approximate Match
… these data for human services requires linking records from all sources. RL (Record Linkage) is a process that connects records that are related to the identical or a sufficiently similar entity from multiple heterogeneous databases. RL is a data and compute intensive, mission critical process. …

Design and development of blocking approaches for record linkage
… PhD project was to contribute to the field of record linkage by proposing innovative solutions that address existing issues among blocking approaches used for record linkage.<br/><br/>A thorough explanation of blocking and record linkage is provided so as to better introduce the reader to these …

Probabilistic Methodology for Record Linkage Determining Robustness of Weights
<p>Record linkage is the process that joins separately recorded pieces of information for a particular individual from one or more sources. To facilitate record linkage, a reliable computer based approach is ideal. In genealogical research computerized record linkage is useful in combing …

Computation of Weights for Probabilistic Record Linkage Using the EM Algorithm
<p>Record linkage is the process of combining information about a single individual from two or more records. Probabilistic record linkage gives weights to each field that is compared. The decision of whether the records should be linked is then determined by the sum of the weights, or “Score”, …

Combination of a Probabilistic-Based and a Rule-Based Approach for Genealogical Record Linkage
<p>Record linkage is the task of identifying records within one or multiple databases that refer to the same entity. Currently, there exist many different approaches for record linkage. Some approaches incorporate the use of heuristic rules, mathematical models, Markov models, or machine learning. …

A record linkage to examine the influence of poor mental health on breast screening uptake
… research dataset.<br/><br/> Breast screening records were obtained from the Quality Assurance Reference Centre (QARC). These were then linked to psychotropic prescribing information from the Enhanced Prescribing Database (EPD), held by the Business Services Organisation (BSO), and subsequently …

Physical Activity and Psychiatric Hospitalizations among Canadian Adolescents and Young Adults: A Longitudinal Study Utilizing Record Linkage
Background: Overwhelming evidence suggests that physical activity in adolescence promotes mental health and prevents mental illness; however, fewer studies have examined these effects in young adults. Furthermore, there is a paucity of research exploring the relationship between physical activity …

The epidemiology of hospital admissions in a general population: record linkage of hospital episode statistics to the European Prospective Investigation of Cancer (EPIC-Norfolk) cohort
… years. All participants were linked to hospital records using their unique NHS numbers and to census data using their postcode. Episode statistics including admission and discharge dates were used to create numbers of admissions and length of stay outcomes. ICD-10 diagnosis codes were used to …

Statistical Methods for Human Rights and Child Mortality Estimation
… We first consider two related problems, record linkage and multiple-systems estimation, typically used to estimate the number of civilian casualties in the wake of a conflict when probability surveys are not available, and then consider the problem of estimating child mortality over time …

Vegetarian Dietary Patterns: Mortality, Colorectal Cancer, and Food Consumption
… Mortality through 2009 was obtained by record linkage with the National Death Index. Cancer incidence data through 2011 was obtained by record linkage with state cancer registries. Cox regression of time-to-event was used as the primary analytic approach for both mortality and colorectal …

Essays in Computational Econometrics
… an improved Bayesian method for probabilistic record linkage in large matching problems, with an accompanying implementation in R/C++, is presented. The method refines the modelling of comparison data relative to previous methods, allowing the distribution of disagreement among non-matched …

One year mortality after hospital admission as an indicator of palliative care need in the Western Cape, South Africa: an incident cohort study
… Retrospective incident cohort study using record linkage of admission and mortality data. Setting: 46 acute care public hospitals in the Western Cape Province of South Africa. Results: Of the 10 761 patients (median age 44 years; IQR: 31 - 60) admitted to 46 hospitals over a 2 week period …

Characterising recent mortality trends in people with bipolar disorder and schizophrenia in England using linked hospital and mortality data
… and comorbid SMI. Method Three separate record linkage studies were undertaken study using Hospital Episode Statistics and death registration data about patients discharged from inpatient care in England between 1999 and 2007. Results Findings showed that the mortality gap widened over …

Death among a cohort of prisoners in New South Wales Australia — a data linkage study
… Wales between January 1988 and December 2002, by record linkage to the Australian National Death Index. The cohort included 76383 men and 8820 women. Over a mean follow-up of 7.7 years, 5137 deaths (4724 men, 423 women) were identified. Three hundred and three deaths (295 men, eight women) …
