David Bowie II (classifying his songs)

last article in my blog was dedicated to David Bowie.

I want to extend it searching relationships in his songs using as a features just his lyrics. Using ununstructured text analysis tools to find the distance between songs (I will use Euclidean distances).

Background

We have lyrics of 254 songs.

Like in last article, we have to convert lyrics to terms, discarding, if possible, the differences between plurals and verbs.

Términos

First of all, we create a word list to discard. Articles, pronoums, ...

i, me, my, myself, we, our, ours, ourselves, you, your, yours, yourself, yourselves, he, him, his, himself, she, her, hers, herself, it, its, itself, they, them, their, theirs, themselves, what, which, who, whom, this, that, these, those, am, is, are, was, were, be, been, being, have, has, had, having, do, does, did, doing, a, an, the, and, but, if, or, because, as, until, while, of, at, by, for, with, about, against, between, into, through, during, before, after, above, below, to, from, up, down, in, out, on, off, over, under, again, further, then, once, here, there, when, where, why, how, all, any, both, each, few, more, most, other, some, such, no, nor, not, only, own, same, so, than, too, very, s, t, can, will, just, don, should, now, d, ll, m, o, re, ve, y, ain, aren, couldn, didn, doesn, hadn, hasn, haven, isn, ma, mightn, mustn, needn, shan, shouldn, wasn, weren, won, wouldn, chorus, 'm, 's, 'll, n't, 'd, ca, wo, oh, yeah, x2.

Then we tokenize al lyrics, e.g., Blackstar lyrics:
