So I have this file in my old version of RapidMiner (5.3):
C:\Program Files (x86)\Rapid-I\RapidMiner5\src\com\rapidminer\tools\math\similarity\nominal\LevenshteinDistance.java
When I open RapidMiner, there is no such operator or extension available, even though it exists in the RapidMiner5\ directory.
How do I access this package and/or operator to use Levenshtein Distance?
Thanks in advance for any help,
