How to find a similarity in email address

Hi All, 

I am a new KNIME user, I am wondering is there any way for KNIME to detect an email address similarity to measure a fraud ?


I need to detect this kind of pattern and then clean up my email list from this kind of email


edit (levensthein) distance as well as jaro Winkler should help you detect duplicates. Fir more efficient treatment consider separating domain from user name (cell splitter) and then to do the similarity search on the user name only.
