The reverse process of stemming

I use a lucene snowball analyzer to perform stemming . The results are not meaningful words . I referred this question .

One of the solution is to use a database that contains a map between the stemmed version of the word to one stable version of the word . (Example from communiti to community no matter what the base was for communti (communities / or some other word))

I want to know if there is a database which performs such a function.
