Re^3: Node Tension

I get pleasing results with this formula:

sub tension {
  my ($hi, $lo) = @_;
  $lo or return 0;
  2 * log($lo)/log($hi + .1);
}

where $hi is the higher number of votes (whichever direction) and $lo is the number of votes in the other direction. Any result above 1 represents an interesting amount of tension, IMO. Here's a table of results:

Hi #	Lo #	Tension
3	3	1.9420
8	3	1.0504
8	8	1.9881
20	3	0.7322
20	8	1.3860
20	20	1.9967
50	3	0.5614
50	8	1.0626
50	20	1.5308
50	50	1.9990
90	3	0.4882
90	8	0.9240
90	20	1.3312
90	50	1.7383
90	90	1.9995

That looks pretty good, except it seems to lose the magnitude of the tension. 3 vs 3, 8 vs 8, 50 vs 50 all have similar results.

(of course that's probably just me visually eyeballing sig figs along a log curve...)

Cheers,

You're right. My notion was only to distinguish interesting from non-interesting. You regain the magnitude if you drop a log:

I'd call < 1.3 low tension, 1.3-2 moderate, >2 strong.
