FCM vectorization for Twitter sentimental analysis using multi stacked BiLSTM

Twitter data analysis gives valuable insights into various aspects of society, such as consumer opinions, political sentiments, brand reputation, and more. This information can help businesses and organizations make informed decisions, track the success of marketing campaigns, and identify emerging trends. Additionally, Twitter data analysis can also aid in research fields such as social sciences and humanities by providing a large, real-time dataset of human behaviour and language. Sentiment Analysis uses natural language processing and machine learning algorithms to categorize tweets as positive, negative, or neutral based on the sentiment expressed in the text. The previous sentiment analysis literature has cited several drawbacks especially on frequency-based vectorization models like Bag of Words, TF-IDF, and traditional word embeddings that generally cannot capture semantic relationships and contextual dependencies in short and noisy Twitter data. The proposed work comprises two phases. In the first phase, text pre-processing, vectorization, word embedding and feature selection is performed using the Frequency Co-occurrence Matrix and Fisher's score algorithm. In the second phase, the Multi stacked BiLSTM is implemented to perform classification as positive, negative and neutral. The performance of the proposed work achieves an accuracy and mean squared error rate as 98% and 0.01% respectively.
