EXPERIMENTAL METHODOLOGY
As mentioned in Section I, our goal is to predict the
winning political party of the Pakistan 2013 elections. For
this, we train predictive models for each party and test them to
predict the winning party. Our prediction (classification)
labels are Pro and Anti; Pro represents a positive sentiment
favoring the party and Anti represents a negative one. We
constructed three separate attribute matrices for each political
party, and use them to construct predictive models using
tweets from 1st January, 2013 till 7th May, 2013. Specifically,
we manually visualized and extracted those tweets for each
party which contained those attributes that represent either a
Pro or Anti opinion. We rejected tweets with a neutral opinion. For example, the PTI matrix contains attributes like
"IMRANKHAN" (sentiment for PTI candidate Imran Khan),
"TEHREEKEINSAAF" (sentiment for PTI),
"IK4NayaPakistan" (support Imran Khan for a New Pakistan),
"StampOnBat" (vote for bat which is the electoral image for
PTI) etc. Having identified the attributes, we then updated the
respective column for an attribute with a ‘0’ if the attribute is
not found in the tweet and ‘1’ if the attribute exists. Finally,
we labeled each tweet with either Pro or Anti. Table I shows a
snapshot of the PTI matrix with both attributes and labels, and
Table II shows a snapshot from the MQM matrix with only
the labels.
