A Bayesian Approach to Graphical Record Linkage and De-duplication
We propose an unsupervised approach for linking records across arbitrarily many files, while simultaneously detecting duplicate records within files. Our key innovation involves the representation of the pattern of links between records as a bipartite graph, in which records are directly linked to latent true individuals, and only indirectly linked to other records. This flexible representation...
متن کاملA Bayesian Approach to Graphical Record Linkage A Simulation Study
We provide a simulation study based on the model in §2.1 and we simulate data from the NLTCS based on our model, with varying levels of distortion. The varying levels of distortion (0, 0.25%, 0.5%, 1%, 2%, 5%) associated with the simulated data are then run using our MCMC algorithm to assess how well we can match under “noisy data.” Figure 3 illustrates an approximate linear relationship with F...
متن کاملImplementing a Bayesian Approach to Record Linkage
The Census Coverage Measurement survey-based program estimated household population coverage of the 2010 Decennial Census. Calculating coverage estimates required linking survey person data to census enumerations. For record linkage research, we applied a Bayesian Latent Class Models approach to both 2010 coverage survey data and simulated household data. This paper presents our use of Base SAS...
متن کاملSMERED: A Bayesian Approach to Graphical Record Linkage and De-duplication
We propose a novel unsupervised approach for linking records across arbitrarily many files, while simultaneously detecting duplicate records within files. Our key innovation is to represent the pattern of links between records as a bipartite graph, in which records are directly linked to latent true individuals, and only indirectly linked to other records. This flexible new representation of th...
