You work for a Marketing agency that monitors the online presence of a few airline companies tounderstand how they are being reviewed. You were asked to identify whether a tweet mentioning anairline is positive, neutral, or negative, and decided to implement a simple sentiment analysisclassifier for this task. What accuracy can you get when automating this process? Is the classifierlikely to help company reviewers save their time? Note: Given the size of the dataset, training theclassifier may take a little while to execute on your machine (especially if you use moresophisticated methods. Feel free to use only a part of the dataset in this challenge if you want tospeed up your solution. Hint 1: Check our Textprocessing extension to learn more about how youcan turn tweets' words into features that a classifier can explore. Hint 2: Study, use, and/or adaptshared components Enrichment and Preprocessing and Document Vectorization (in this order!) ifyou want to get a part of the work done more quickly. They were created especially for thischallenge. Hint 3: Remember to partition the dataset into training and test set in order to create thedecision tree model and then evaluate it. Feel free to use the partitioning strategy you prefer.
