Aggregate queries on probabilistic record linkages [PDF]

Proceedings of the 15th International Conference on Extending Database Technology, 2012
Record linkage analysis, which matches records referring to the same real world entities from different data sets, is an important task in data integration. Uncertainty often exists in record linkages due to incompleteness or ambiguity in data.

Duplicate Detection in Probabilistic Data [PDF]

, 2009
Collected data often contains uncertainties. Probabilistic databases have been proposed to manage uncertain data. To combine data from multiple autonomous probabilistic databases, an integration of probabilistic data has to be performed.

An Introduction to Probabilistic Record Linkage [PDF]

, 2020
Since its post-World War II inception, the science of record linkage has grown exponentially and is used across industrial, governmental, and academic agencies. The academic fields that rely on record linkage are diverse, ranging from history to public health to demography.

Probabilistic linkage to enhance deterministic algorithms and reduce data linkage errors in hospital administrative data. [PDF]

, 2017
BACKGROUND: The pseudonymisation algorithm used to link together episodes of care belonging to the same patients in England (HESID) has never undergone any formal evaluation, to determine the extent of data linkage error.

A Probabilistic Record Linkage Model for Survival Data [PDF]

Journal of the American Statistical Association, 2017
AbstractIn absence of an unique identifier, combining information from multiple files relies on partially identifying variables (e.g. gender, initials). With a record linkage procedure, these variables are used to distinguish record pairs that belong together (matches) from record pairs that do not belong together (non-matches). Generally, the combined

HIV and cancer registry linkage identifies a substantial burden of cancers in persons with HIV in India. [PDF]

, 2016
We utilized computerized record-linkage methods to link HIV and cancer databases with limited unique identifiers in Pune, India, to determine feasibility of linkage and obtain preliminary estimates of cancer risk in persons living with HIV (PLHIV) as ...

Revisiting the probabilistic method of record linkage

CoRR, 2019
In theory, the probabilistic linkage method provides two distinct advantages over non-probabilistic methods, including minimal rates of linkage error and accurate measures of these rates for data users. However, implementations can fall short of these expectations either because the conditional independence assumption is made, or because a model with ...

Validating Distance-Based Record Linkage with Probabilistic Record Linkage [PDF]

, 2002
This work compares two alternative methods for record linkage: distance based and probabilistic record linkage. It compares the performance of both approaches when data is categorical. To that end, a distance over ordinal and nominal scales is defined.

Probabilistic Clustering of Time-Evolving Distance Data [PDF]

, 2015
We present a novel probabilistic clustering model for objects that are represented via pairwise distances and observed at different time points. The proposed method utilizes the information given by adjacent time points to find the underlying cluster ...
