However, use of social media platform carries high probability of misinformation. In 2018, many parents decided to completely stop getting their children vaccinated due to the Dengvaxia scandal, which resulted to several measles outbreaks. Social media platform contributed to the fast information dissemination regarding the danger of Dengvaxia which created a negative perception towards vaccines in general. The study identified how information regarding the adverse effects of Dengvaxia spread on Twitter. Doc2vec was compared to n-gram neural network classification in order to identify Public Perception on Health Tweets (PPHT). The diffusion characteristics and its corresponding centrality measures was used to model the spread of PPHT and Non-PPHT. The result shows that bigram neural network has the highest performance measure with 85.57% accuracy, 85% precision, 86% recall and 85% F1 score. Moreover, the most influential PPHT comes from Youtube video shares, news agencies and its associates. While influential mediators are users that mostly post tweets to support a particular administration (i.e., Duterte admin). PPHT spreads deeper and has more replies than Non-PPHT, but has a lower structural virality and number of favorites. 2019-01-01T08:00:00Z text https://archium.ateneo.edu/theses-dissertations/131 http://rizalls.lib.admu.edu.ph/#section=resource&resourceid=2026402949&currentIndex=0&view=fullDetailsDetailsTab Theses and Dissertations (All) Archīum Ateneo Twitter Medical informatics Public health -- Information services Social media in medicine Health -- Computer network resources Vaccination -- Philippines -- Case studies.Data mining.
