Tweet Sentiment Extraction using Viterbi Algorithm with Transfer Learning
This work addresses sentiment analysis for social media users, but it appears incremental as it builds on an existing modified algorithm.
The research tackled tweet sentiment extraction by enhancing a modified Viterbi algorithm with transfer learning and confidence indicators, resulting in a highly explainable model that precisely identifies low-confidence predictions and tracks tuning improvements.
Tweet sentiment extraction extracts the most significant portion of the sentence, determining whether the sentiment is positive or negative. This research aims to identify the part of tweet sentences that strikes any emotion. To reach this objective, we continue improving the Viterbi algorithm previously modified by the author to make it able to receive pre-trained model parameters. We introduce the confidence score and vector as two indicators responsible for evaluating the model internally before assessing the final results. We then present a method to fine-tune this nonparametric model. We found that the model gets highly explainable as the confidence score vector reveals precisely where the least confidence predicted states are and if the modifications approved ameliorate the confidence score or if the tuning is going in the wrong direction.
