Hi, You may look out for plagirism detectors.
My approach would be : 1. Hash all the keywords in one file and keep the count. 2. For each keyword in the other file , check if it exists in the hash table , decrement its count. Also increment a counter which represents the similarity between the two docs. For percentage you might also count the total keywords in the second doc and do "found keywords"/ total keywords.
