Comparison with SimString

[KrishnaPG]

Not sure if it is a right question, but given that SimString does efficient approximate search / string lookups from a large database, wondering how CRFSuite is different or better?

I understand there is some technical difference at the algorithmic level how each is implemented differently, but at the practical use-case and result level are there scenarios where:

• CRFSuite is more suited than SimString (i.e. SimString cannot give correct results but CRFSuite does) and
• SimString is better (i.e. CRFSuite cannot give correct results but SimString does)?

Also, is it not the case that CRF once built cannot be modified (or added new strings) and that SimString being a DB-based can add new strings on the fly to the DB?
