3.3 Find Keywords Similarity

We use Levenshtein distance. This distance is computed by finding the number of edits which will transform one string to another. The transformations allowed are insertion — adding a new character, deletion — deleting a character and substitution — replace one character by another. By performing these three operations, the algorithm tries to modify first string to match the second one.

In [15]:
# find similar keyword by applying levensthein algorithm with simillarity threshold value between 0.91 and 1.
# the output is in list of tuple of the keywords and its similar words
