Matching algorithm

Aug 14, 2017

When searching for matches between discovered and managed applications, AppDNA compares the application name, manufacturer, and version, and awards points. The Discover Applications screen includes a Best Suggestion value that indicates whether there are any managed applications that are possible matches for the application and if so, how close the match is.

The points awarded are as follows.

Detail	Full Match	Partial Match
Name	50 points	25 + 1 point per word
Manufacturer	10 points	1 point per word
Version	10 points	1 point per word

AppDNA adds the points and assigns a confidence value to the match as follows:

Best Suggestion values	Total Points
Perfect	70
Excellent	More than 50
Good	More than 45 (Partial match on name + full match on manufacturer AND version)
Average	More than 35 (Partial match on name + full match on manufacturer OR version)
Poor	More than 25
No Match	Less than 25
