Transforming Dataset using TF-IDF Vectorizer.Splitting our data into Train and Test sets.The various steps involved in the Machine Learning Pipeline are: Twitter Sentiment Analysis: Project Pipeline text: It refers to the text of the tweet.user: It refers to the name of the user that tweeted.If no such query exists, then it is NO QUERY. target: the polarity of the tweet (positive or negative).The various columns present in this Twitter data are: The dataset provided is the Sentiment140 Dataset which consists of 1,600,000 tweets that have been extracted using the Twitter API. The necessary details regarding the dataset involving the Twitter sentiment analysis project are: We will be classifying the tweets into positive or negative sentiments. In this project, we try to implement an NLP Twitter sentiment analysis model that helps to overcome the challenges of sentiment classification of tweets. Twitter Sentiment Analysis: Problem Statement The performance of these classifiers is then evaluated using accuracy and F1 Scores.įor data preprocessing, we will be using Natural Language Processing’s (NLP) NLTK library. In this article, we aim to analyze Twitter sentiment analysis using machine learning algorithms, the sentiment of tweets provided from the Sentiment140 dataset by developing a machine learning pipeline involving the use of three classifiers ( Logistic Regression, Bernoulli Naive Bayes, and SVM)along with using Term Frequency- Inverse Document Frequency ( TF-IDF).
