Example of the calculation for the comment vectors

Word	Dimension
Word	1	…	298	299	300
Comment 1
Lovely	0.045		−0.011	−0.003	0.004
Smile	0.154		−0.051	0.071	−0.035
Average	0.0995a		−0.031	0.034	−0.0155
Vector of comment 1 = [0.0995, …, −0.031, 0.034, −0.0155] ^a(0.045 + 0.154)/2 = 0.0995
Comment 2
Refreshing	0.004		0.014	0.027	−0.004
Flavor	−0.003		0.117	−0.028	−0.017
Average	0.0005		0.0655	−0.0005	−0.0105

Vector of comment 2 = [0.0005, …, 0.0655, −0.0005, −0.0105]

Note(s): The word vectors of “lovely,” “smile,” “refreshing” and “flavor” are taken from fastText and each word vector has 300 dimensions
