Social Media Analysis: Social media data contains valuable information about user preferences and opinions, making it an important source for sentiment analysis and NLP tasks. In the study by Rita et al. (2023), they analyze tweets during an electoral period to understand the impact of social media on voting decisions. Their findings suggest that while sentiment analysis of social media content provides insight into public opinion, it may not be an accurate predictor of election outcomes. In the paper by Qaqish et al. (2023), the authors analyzed the sentiment of tweets on the post-COVID transition to hybrid learning in the Jordanian community. Their findings revealed that 18.75% of the studied sample expressed dissatisfaction, suggesting the importance of understanding and interpreting user sentiments in social networks.

Data Mining: Data mining refers to the process of discovering patterns and extracting valuable information from large datasets. In the work of Qaqish et al. (2023), the authors used data mining classifiers, such as k-nearest neighbor, decision tree, and naive Bayes, to analyze the sentiment of tweets from the Arabic-Egyptian Corpus 2 dataset. They reported that deep learning models coupled with ensemble learning improved the overall sentiment classification performance.


Ensemble Learning: Ensemble learning combines multiple learning algorithms to create a more robust model with better performance than any single algorithm. In the study by AminiMotlagh et al. (2023), the authors utilized ensemble techniques to decrease variance and bias in their learning algorithms, resulting in increased reliability of their single classifiers. Verma et al. (2022) employed an NLP-based algorithm to perform opinion mining on Twitter data and performed ensemble learning to analyze and evaluate the public sentiment towards COVID-19 vaccines in India. Mohamed et al. (2023) proposed an ensemble learning approach that combines multiple transformer-based models, such as XLM-T and MARBERT, to tackle the challenges faced in Arabic sentiment analysis. Their results show that the ensemble approach outperforms individual state-of-the-art models on all tested datasets.
