Out of curiosity I tried the capitalized form vs the non capitalized form in Google ngram.
Being astonished by the high number of hits for the Capitalized form I retried this with the more innocent noun house.
I do not understand the results. I think all the words a normally written in the non capitalized form, except when used in titles or at the beginning of the sentence.
All this looks rather arbitrary to me and I have the impression that I would choose a case insensitive option if only I had a chance to do so.
Is this just another shortcoming of Google ngram or is this a problem for other ngram viewers too, and I have to care to set some options explicitly?
