<p>[QUOTE="dougsmit, post: 4144805, member: 19463"]I would say that is absolutely ridiculous were it not for the fact that almost no coins are listed by dealers graded 'Good' (AKA not good enough to be VG). Good is used for two different purposes. Your data mining needs to be able to distinguish between 'Goods' followed by another grade term (F, VF. EF) and 'Goods' meant to stand alone indicating a low grade coin. Similarly you will encounter hyphenated grades meaning between (G-VG, F-VF) and split grades where the listing indicates the two sides of the coin are not equal (F/G). Simply mining words without meaning is, well, meaningless. </p><p><br /></p><p>Automated data mining reminds me of books written by professional writers who knew nothing about the subject before they were assigned the project. The book can end up spreading more ignorance than it educates. Of course there is the other problem of experts who have no idea how to communicate their knowledge to human beings who do not already know the subject. I suppose that these efforts might eventually grow and develop rather like Google of 2020 is better than Altavista of 1995.
