Exploring Sentiment Analysis Approaches in a Public Agency Security News Dataset
Summary
A study investigated deep learning algorithms for sentiment analysis of news headlines concerning a public security institution, aligning with its 2024–2027 strategic plan to enhance public image. Researchers applied four deep learning methods combined with three textual representations, yielding twelve distinct models. The analysis included a class-based evaluation for each combination. Models leveraging BERT for textual representation demonstrated robust performance, achieving an F1-score of approximately 90%. This research aims to help the institution understand media portrayal and strengthen its public image.
Key takeaway
For public relations teams or communication strategists monitoring media sentiment, this research indicates that deep learning models, especially those utilizing BERT, offer a highly effective approach. You should consider implementing BERT-based sentiment analysis to accurately gauge public perception from news headlines, informing strategic communication efforts and image management.
