I was thinking about something similar once, A possible solution is to
use the Levenshtein distance algorithm
(http://en.wikipedia.org/wiki/Levenshtein_distance)
But there could be quite a processing overhead, I mean where do you
place the alorithm? If it's in the scheduler then it would run
excesivly. But if it was in the grab/mythfilldatabase place, then you
have to make a decision about which description to use (probably
easier, e.g. use the first one).
