^ W : a x r y (b1 - b2)
Here, W is the word associated with the burst, a is the number of bins
spanned by the burst interval, x is the weight of the burst,
r is the reciprocal of the rate associated with the burst state,
and b1 and b2 are the names of starting and ending bins.
USE: cat burst_core.txt  | sort -nr +4 | head -30 | sort +7  to obtain
the top 30 burst-words based on 'x' i.e. WEIGHT of the burst
