@edgarblythe,
I'm reading a book called
The Shakespeare Wars by Ron Rosenbaum which deals with all of the quarrels and frauds and public embarrassments surrounding current studies/stagings of Shakespeare.
Rosenbaum writes at length of a man named Don Foster, who exposed Anonymous of
Primary Colors fame. The other thing Foster did (this is an extreme egotist) was to "discover" a lost poem of Shakespeare's called, "A Funerall Elegye,"using a data base he put together which he called SHAXICON.
To make a long story short, Foster is a boob whose ego led him to make ridiculous proclamations as well as an international figure of derision. The poem in question is now attributed to a minor Jacobean writer, John Ford, whose big success was a play, '
Tis Pity She's A Whore.
The mistake was discovered by a Swiss scholar doing what is known as a close reading of the text because a French publishing house wanted a translation into French. But, before it was discovered, scholars throughout the world lined up on either side of the debate, with the Times Literary Supplement backing Foster.
The point of all this is that Foster relied on a computer analysis. No one knows what Foster's database looked like because Foster never produced it. Rosenbaum theorizes that is was based on word count rather than analysis.
And that is akin to what I Write Like . . . is.
I Write Like is a parlour game, deserving of the British rather than the AMerican spelling.
No, it can not guarantee that your writing is to a high standard. I suspect this program may have had some paragraphs of several authors scanned into it. At its most sophisticated, it compares . . . and this is sheer conjecture on my part . . . the use of certain parts of speech and the order of your sentences.
The caution is, "At its most sophisticate . . ." because we have no idea how sophisticated it is. All if does is note a resemblance, a predilection to use certain . . . shall we call them stylistic notes . . . over others.
