Record linkage (also known as data matching, data linkage, entity resolution, and many other terms) is the task of finding records in a data set that refer to the same entity across different data sources (e.g., data files, books, websites, and databases).
The goal of matching is to reduce bias for the estimated treatment effect in an observational-data study, by finding, for every treated unit, one (or more) non-treated unit(s) with similar observable characteristics against which the covariates are balanced out (similar to the K-nearest neighbors algorithm).
A SWOT analysis can be used to generate matching and converting strategies. [16] Matching refers to seeking competitive advantage by matching strengths to opportunities. Conversion refers to converting weaknesses or threats into strengths or opportunities. An example of a conversion strategy is to buy off a threat through collaboration or ...
TDA is a powerful program, offering access to some of the latest developments in transition data analysis. STATA has implemented a package to run optimal matching analysis. TraMineR is an open source R -package for analyzing and visualizing states and events sequences, including optimal matching analysis.
Data cleaning is the process of preventing and correcting these errors. Common tasks include record matching, identifying inaccuracy of data, overall quality of existing data, deduplication, and column segmentation. [23] Such data problems can also be identified through a variety of analytical techniques.
Template matching theory describes the most basic approach to human pattern recognition. It is a theory that assumes every perceived object is stored as a "template" into long-term memory. [ 4 ] Incoming information is compared to these templates to find an exact match. [ 5 ]

In computing and data management, data mapping is the process of creating data element mappings between two distinct data models. Data mapping is used as a first step for a wide variety of data integration tasks, including: [1] Data transformation or data mediation between a data source and a destination
