It turns out this text is not so interesting because there is so much 'formula', for want of a better word, and these large parts of 'formula'-sentence while meaning little will give the comparison a high hit number -- see below. By the way, this will be the same for the approach of Algorithm::Diff's LCS (the TK program that tybalt89 made you). I think, anyway.

Yesterday, I generated comparisons and kept all above 0.25. This produced a table with almost 40M comparisons with their 'similarity' number.

It 'worked', in a way, but the result is still a bit disappointing because of the type of text this is (I think). A more real information text with less repetition, less fluff, if you see what I mean, might be more interesting.

select
    substring(cmp.sim::text,1,5) sim
  ,    k1.text || chr(10)
    || k2.text || chr(10)

from   kjv_simil_0_25 cmp   -- big table
  join kjv k1 on id1=k1.id  -- table from the KJV file
  join kjv k2 on id2=k2.id  --   ,,

where k1.book = 50  -- look at just this book
  and sim > 0.7   -- remove too different
  and sim < 0.85  -- remove too identical
;

  sim  |

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
