Sentiment Analysis on COVID Tweets: An Experimental Analysis on the Impact of Count Vectorizer and TF-IDF on Sentiment Predictions using Deep Learning Models

Ghulam Musa Raza et al.

Summary: Due to the higher popularity and excessive use of social media, COVID-19 has become the talk of the town since 2019, causing stress, anxiety, and depression worldwide. In this article, we experimented with different classifiers on COVID data to train deep neural networks using two word embedding techniques: Count Vectorizer and TF-IDF. We found that TF-IDF is more efficient in cases of large datasets, but Count Vectorizer outperforms in accuracy by 10% on Single Layer Perceptron in the context of covid19 tweets.
