Sample text

Therefore the grouping process may be viewed as a process of computing the transitive closure2. This chapter uses the term “transitive closure” to refer to the grouping problem that has to be addressed in a preprocessing step. 2 Literature Review The grouping process this chapter addresses is often referred to as “blocking methods” in the literature by Baxter et al. (2003), which have been found beneficial in solving problems such as record linkage, data cleaning, data purging/merging, and data enhancement.

Knowing record 1 and record 2 refer to the same individual, we might fill in the cell phone information for record 1 if this field is blank or enhance the database of record 1 by adding a cell phone column. Likewise, record 2 might be made more complete by having an email address. We might even build and develop a new database, which “combines” the two databases with enhancement, such as the example illustrates. Notices that relational operator “joint” cannot be performed due to the lack of common key from different data sources.
