Bidirectional Encoder Representations for Transformer, is the most famous transformer-based encoder model that learns excellent representations for text. Sentiment Analysis is the analysis of how much a text document is positive, negative and opinionated.

The task of determining whether a comment contains inappropriate text that affects either individual or group is called offensive language identification. The existing research has concentrated more on sentiment analysis and offensive language identification in a monolingual data set than code-mixed data. Code-mixed data is framed by combining words and phrases from two or more distinct languages in a single text. It is quite challenging to identify emotion or offensive terms in the comments since noise exists in code-mixed data. The majority of advancements in hostile language detection and sentiment analysis are made on monolingual data for languages with high resource requirements.

Also, the performance of hybrid models that use multiple feature representations (word and character) may be studied and evaluated. Figure 2 shows the training and validation set accuracy and loss values using Bi-LSTM model for sentiment analysis. From the figure it is observed that training accuracy increases and loss decreases. So, the model performs well for sentiment analysis when compared to other pre-trained models.
