Re: Re: Re: Text Analysis Tools to compare Slinker and Stinker?

But, having used the Fathom module, see above, I've got nothing conclusive, I'm afraid. It's a very useful tool but hasn't proven or disproven anything. There are fewer differences between two randomly-chosen posters than between Slinker and Stinker, it turns out.

Another angle of attack on this problem, which I hadn't thought of before, is mis-spellings -- Slinker has spelt "happening" as "happenning" twice, but Stinker gets it right every time...

Leaving alone the issue of whether it is really worth it to spend a lot of time on this mystery, testing services have dealt with some aspects of your problem. Especially the personality tests where they ask you the same question in many slightly different ways and perform some kind of analysis to determine whether you are trying to spoof the test by appearing to be someone you are not.

Your mention of a spelling discrepency brought to mind a scene from The Princess Bride where Westley was to add poison to one of the drinks, and his adversary was to choose, after Westley had shifted (or not) the position of the glasses. The bad guy goes through a series of qustions and answers trying to figure out Westley's thoughts -- "You placed the poisoned glass closer to me so I'd choose it. But I'm too smart for that, so it must be the one closest to you... But you knew I'd anticipate that move, so it must be the one closest to me after all." And so on for a few minutes or pretty funny dialogue. (I'm sure I got the details turned around, but you get the gist)

Is this guy deliberately mispelling a word or two just to throw you off? Does it really matter? It still boils down to a guess, doesn't it?

Even after centuries of linguistic analysis, and lately with some fairly sophisticated computer analysis, scholars are still arguing whether Marlowe wrote the works attributed to Shakespeare, or whether Shakespeare was, indeed, Shakespeare.

Man in black:  (turning his back, and adding the poison to one of the goblets)
	Alright, where is the poison?  The battle of wits has begun.  It ends
	when you decide and we both drink - and find out who is right, and who
	is dead.
Vizzini:  But it's so simple.  All I have to do is divine it from what I know of
	you.  Are you the sort of man who would put the poison into his own
	goblet or his enemy's? Now, a clever man would put the poison into his
	own goblet because he would know that only a great fool would reach for
	what he was given.  I am not a great fool so I can clearly not choose
	the wine in front of you...But you must have known I was not a great
	fool; you would have counted on it, so I can clearly not choose the wine
	in front of me.
Man in black:  You've made your decision then?
Vizzini:  (happily) Not remotely!  Because Iocaine comes from Australia.  As
	everyone knows, Australia is entirely peopled with criminals.  And
	criminals are used to having people not  trust them, as you are not
	trusted by me.	So, I can clearly not choose the wine in front of you.
Man in black:  Truly, you have a dizzying intellect.
Vizzini:  Wait 'till I get going!!  ...where was I?
Man in black:  Australia.
Vizzini:  Yes! Australia!  And you must have suspected I would have known the
	powder's origin,so I can clearly not choose the wine in front of me.
Man in black:  You're just stalling now.
Vizzini:  You'd like to think that, wouldn't you!  You've beaten my giant, which
	means you're exceptionally strong...so you could have put the poison in
	your own goblet trusting on your strength to save you, so I can clearly
	not choose the wine in front of you.  But, you've also bested my
	Spaniard, which means you must have studied...and in studying you must
	have learned that man is mortal so you would have put the poison as far
	from yourself as possible, so I can clearly not choose the wine in front
	of me!

Man in black:  You're trying to trick me into giving away something.  It won't
	work.
Vizzini:  It has worked!  You've given everything away! I know where the poison
	is!
Man in black:  Then make your choice.
Vizzini:  I will, and I choose...(pointing behind the man in black) What in the
	world can that be?
Man in black:  (turning around, while Vizzini switches goblets) What?! Where?! I
	don't see anything.
Vizzini:  Oh, well, I...I could have sworn I saw something. No matter.	(Vizzini
	laughs)
Man in black:  What's so funny?
Vizzini:  I...I'll tell you in a minute.  First, lets drink, me from my glass
	and you from yours.

(They both drink)

I still maintain that this was in interesting exercise.

I did one other thing, which was brute-force but also interesting.

I grabbed every 2-char string from the posters, put them in a hash with number of occurrences, sorted the results by number, and compared the most popular 1,000 2-char strings from the suspect posters with the most popular 2-char strings from "real" posters. Again, the results were inconclusive.

Slinker and Stinker shared 75% of the most-popular-strings, but another poster shared 68%, so it wasn't very dramatic evidence either way.
