Rating Of Indonesian sinetron based on public opinion in Twitter using Cosine similarity

Abstract

Sinetron is a frequently watched television program in Indonesia. However, there are many sinetron featuring scenes that are not suitable for a certain age group viewers. Viewers who feel disappointed with some sinetron often express their opinion on social media, especially twitter. This research aimed to categorize sinetron into the age groups: A (Children), R (Teen), or D (Adults) based on the results of similarity calculation between tweets and chapters of Indonesian Broadcasting Commision regulations, or called P3&SPS KPI 2012. The calculation of similarity is done by combining Cosine similarity method with Term Frequency (TF) and Term Frequency-Inverse Document Frequency (TF-IDF). The results of experiments showed that the combination of Cosine similarity and TF-IDF gives better accuracy than the combination of Cosine similarity and Term Frequency. In addition, the results of sinetron categorization based on people opinions posted in Twitter in many cases are not match with the result of categorization established by Indonesian Broadcasting Commision (KPI).
