Date Comparison Algorithm

The date compare routine is used to intelligently determine the similarity of two dates. The routine uses the strength of NameSearch to arrive at its results.

The date comparison routine interrogates two dates by parsing them into their components. The month and day represent one component, which accounts for half the score; the year field represents the other half.

The first part of the scoring routine is the parsing of information. The majority of this work is accomplished through the use of NameSearch’s sanitization and word recognition routines. These routines use the date service, supplied with the NameSearch software, to arrive at its results. Do not modify the date service since this may result in unpredictable scoring results.

After the dates have been parsed and standardized, the date comparison back-end calculates a score between 0 and 100.
