Abstract
Using text mining approach, this study explored the common themes surrounding the
social media users’ discussions regarding the recent killing of Sonya and Frank Gregorio which
sparked conversation on Twitter in the Philippines. Using keywords from the trending hashtags
#StopKillingsPH and #JusticeforSonyaGregorio, tweets were extracted via Python program. A
total of 1,045 tweets from December 21 to December 28, 2020 were collected and analyzed in
terms of frequency, sentiment, subjectivity, and surrounding themes. Results show that
discussions regarding the Gregorio murder revolved on the netizen’s call for justice, demand that
the suspect be charged with murder, and an online petition and a louder plea to stop killings and
end police brutality in the country. Finally, this study may show how social media can be
influential in mobilizing the authorities to act against injustices in the Philippines and in affecting
change in the society.
