Pre-trained word embedding’s are used in several downstream applications as well as for constructing representations for sentences, paragraphs, and documents. One improvement area is reducing the dimensionality of word embedding. Reducing the size of word embedding can improve their utility in memory-constrained devices, benefiting several real-world applications. Therefore, in this paper, we focus on how to classify textual information, which consists of online comments from Wikipedia talk page edits where unsupervised learning approaches are used to obtain better performance of sentimental analysis. To this end, we first analyze the dataset for pre-training by using a phenomenon called glove word embedding and giving some unique dimensions to each comment. Then we reduce the dimensions of the comments using the dimensionality reduction approach and propose an iterative algorithm called t-SNE to visualize the high-dimensional data. Finally, a bidirectional LSTM model is built using keras to classify the sentences into appropriate types of toxicity. To the best of our knowledge, this work is first to the study of negative online behaviors, like various types of toxic comments.
