Sentiment Analysis in Social Media
Research Guide
What is Sentiment Analysis in Social Media?
Sentiment Analysis in Social Media identifies sentiments and opinions from social media posts using machine learning techniques like random forests and natural language processing for public opinion mining.
Researchers apply random forests (Karthika et al., 2019, 99 citations) and NLP data extraction (Mishra et al., 2022, 55 citations) to analyze sentiments in social media texts. Studies target applications in women's safety (Anisha et al., 2022; Nanditha, 2022) and bullying detection (Kumar et al., 2020). Over 10 papers since 2019 focus on domain adaptation for social issues.
Why It Matters
Sentiment analysis from social media supports real-time crisis response, such as monitoring women's safety via tweets (Anisha et al., 2022; Nanditha, 2022). It enables public opinion mining for smart cities and health monitoring using random forest classifiers (Karthika et al., 2019). Applications include bullying detection in schools (Kumar et al., 2020) and personality analysis in chats (Thakur and Krishnaraj, 2024), aiding decision support systems.
Key Research Challenges
Domain Adaptation Shortfalls
Social media texts vary by domain like safety or health, reducing model accuracy without adaptation. Karthika et al. (2019) used random forests but noted limitations in noisy data. Mishra et al. (2022) highlighted NLP extraction challenges across contexts.
Handling Sarcasm Noisy Data
Sarcasm and slang in posts confuse sentiment classifiers. Kumar et al. (2020) faced issues detecting bullying nuances in social media. Anisha et al. (2022) reported low precision on informal tweets for safety analysis.
Scalability Real-Time Processing
Processing high-volume social streams demands efficient models. Nanditha (2022) struggled with real-time women's safety predictions from large datasets. Thakur and Krishnaraj (2024) noted computational limits in WhatsApp chat analysis.
