Linking historical census data across time is a challenging task due to various reasons, including data quality, limited individual information, and changes to households over time. Although most census data linking methods link records that correspond to individual household members, recent advances show that linking households as a whole provide more accurate results and less multiple househo...

In this article we investigate how approximate query processing (AQP) can be used in medical multidatabase systems. We identify two areas where this estimation technique will be of use. First, approximate query processing can be used to preprocess medical record linking in the multidatabase. Second, approximate answers can be given for aggregate queries. In the case of multidatabase systems use...

Recent times have seen an increased interest into techniques that allow the linking of records across databases. The main challenges of record linkage are (1) scalability to the increasingly large databases common today; (2) accurate and efficient classification of compared records into matches and non-matches in the presence of variations and errors in the data; and (3) privacy issues that occ...

We present a probabilistic method for linking multiple datafiles. This task is not trivial in the absence of unique identifiers for the individuals recorded. This is a common scenario when linking census data to coverage measurement surveys for census coverage evaluation, and in general when multiple record–systems need to be integrated for posterior analysis. Our method generalizes the Fellegi...

Historical census data provide a snapshot of the era when our ancestors lived. Such data contain valuable information that allows the reconstruction of households and the tracking of family changes across time, allows the analysis of family diseases, and facilitates a variety of social science research. One particular topic of interest in historical census data analysis are households and linki...

Record linkage is a powerful tool in assembling information from different data sources and has been used by a number of public health researchers. In this review, we provide an overview of the record linkage methodologies, focusing particularly on probabilistic record linkage. We then stress the purposes and research applications of linking records by focusing on studies of infant health outco...

A fine-grained record integration and linkage tool (FRIL) is presented. The tool extends traditional record linkage tools with a richer set of parameters. Users may systematically and iteratively explore the optimal combination of parameter values to enhance linking performance and accuracy. Results of linking a birth defects monitoring program and birth certificate data using FRIL show 99% pre...

linking or matching databases is becoming increasingly important in many data mining projects, as linked data can contain information that is not available otherwise, or that would be too expensive to collect. a main challenge when linking large databases is the complexity of the linkage process: potentially each record in one database has to be compared with all records in the other database. ...

In order to carry out demographic analyses at individual and group levels, a manual method of linking individual event records from parish registers was developed in the late 1950s. In order to save time and to work with larger areas than small parishes, systems for automatic record linkage were developed a couple of decades later. A third method, an interactive record linkage, named Demolink, ...

Abstract Record linkage is the process of bringing together same entity from overlapping data sources while removing duplicates. Huge amounts are now being collected by public or private organizations as well researchers and individuals. Linking analysing relevant information this massive reservoir can provide new insights into society. It has become increasingly important to have effective eff...
