Abstract
The increasing need of statistical information, the increasing cost of ad hoc statistical surveys with a decreasing participation rate, and the increasing number of sources of information, are common today's problems.
A promising response is to integrate data from different sources into a unique, synthetic data-file containing all necessary information. Data integration plays an important role in data gathering process, with serious consequences in data usage.
This talk focuses on the two main problems of data integration, namely record linkage and statistical matching. The two problems are described, and the main concepts and techniques are introduced.
