Record Linkage is the task of identifying which records in a database refer to the same entity. A standard machine learning approach to this problem is to train a model that assigns scores to pairs of records where pairs scoring above a threshold are said to represent the same entity. However, it is too expensive to make pairwise comparisons among all records in large databases. “Blocking” is t...

Record linkage is the process of identifying records that refer to the same entities from different data sources. While most research efforts are concerned with linking individual records, new approaches have recently been proposed to link groups of records across databases. Group record linkage aims to determine if two groups of records in two databases refer to the same entity or not. One app...

Record Linkage is used to link records of two different files corresponding to the same individuals. These algorithms are used for database integration. In data privacy, these algorithms are used to evaluate the disclosure risk of a protected data set by linking records that belong to the same individual. The degree of success when linking the original (unprotected data) with the protected data...

Recent years have seen the development of novel techniques for linking complex types of data that contain records about different types of entities, for example bibliographic databases with records about authors, publications, and venues. Advanced approaches have been devised to link individuals and groups of records. These approaches exploit both the similarities between record attributes as w...

Let me start with the simplest possible definition of record linkage. There is a single record as well as a file of records and all records relate to some entities: persons, businesses, addresses, etc. Record linkage is the operation that, using the identifying information contained in the single record, seeks another record in the file referring to the same entity. If one accepts this definiti...

R linkage, in the present context, is simply the bringing together of information from two records that are believed to relate to the same entity—for example, the same individual, the same family, or the same business. This might involve the linking of records within a single database to identify duplicate case records. Alternatively, record linkage might involve the linking of records across t...
