There are. And they have been very successful in making attributions and solving literary mysteries. One of these programs demonstrated that Christopher Marlowe made some contributions to some of the "iffy" works in the Shakespeare canon that scholars have been arguing about for years but did not contribute to any of the principal, widely-accepted plays and poetry. If the supporters of de Vere are confident, they'll submit his works to this type of analysis as well.
Personally, I think the subject is fascinating, and I'd love to know who the real author of the Shakespeare plays was. I can't believe it was an uneducated, untravelled guy from a two-bit village who left not a single book, manuscript, or paper in his will. But the mystery is endlessly enchanting, isn't it?
Few think that Christopher Marlowe had anything to do with the works in the Shakespeare canon, except as influence. I do know that not one program has "demonstrated" Marlowe's hand in any of these plays. At best, it could only provide compelling evidence, but I don't think even that much has been done. The most widely accepted contributors to the Shakespeare canon are John Fletcher (in "Henry VIII" and "The Two Noble Kinsmen"), George Wilkins (first two acts of "Pericles"), and Thomas Nashe (first act of "Henry VI, part 1").
I can't believe it was an uneducated, untravelled guy from a two-bit village who left not a single book, manuscript, or paper in his will.
And how do you know Shakespeare was uneducated and untravelled? As for the will, we have other wills from fourteen different playwrights of the time, and only three mention books. Sir Francis Bacon never mentioned books in his will either. It just doesn't mean anything.
