Project Title: Sentiment Analysis (stage 1) Goal: The goal of this assignment is to help students familiarize themselves with the following Java programming concepts: 1. Input/Output to and from the terminal. 2. Storing data in a file and reading data from a file 3. Creating object-oriented classes and methods to handle data. 4. Using data structures to store data in main memory (e.g. HashSet) 5. Working with character strings. 6. Using Javadoc comments and generating and html documentation of the program Description: For this assignment you will create a program to classify a set of movie reviews as positive or negative based on their sentiment. This process is known as Sentiment Analysis, and there are multiple approaches to analyze the data and estimate the sentiment. More information about sentiment analysis can be found on Wikipedia and other sources. https://en.wikipedia.org/wiki/Sentiment analysis In this assignment, vou are to write a Java program that will classifv a review as positive or negative by counting the number of positive and negative words that appear in that review. Your program will have multiple inputs as command line arguments Paths to two text files: list of positive words (positive-words.txt) and list of negative words (negative-words.txt) Paths to two folders: the folder 'pos' contains the positive reviews and the folder 'neg' contains the negative reviews, both manually assigned by humans. The reviews within each folder are given in separate .txt files, one review per file Your class containing the main() method should be named SentimentAnalysisApp and it should accept the following command line arguments: java sentimentAnalysisApp Run example (assumes Data directory is under the current directory) >java SentimentAnalysisApp ./Data/positive-words.txt ./Dataegative- words.txt ./Data/Movie-reviews/pos . /Data/Movie-reviewseg Your Java program will automatically classify the .txt files in the folders, and output the total count of how many were correctly classified, compared to the human ground truth. Your Java program should operate in the following manner: 1. The program loads the positive words and negative words and stores them in two separate lookup tables. The HashSet data structure can be used as a lookup table in Java as it provides a fast way to look if a word exists in it or not The program iterates over the .txt files and, in each file, it counts the number of positive and negative words that the review contains. If the review contains more positive than negative words it is classified as positive, and vice versa. If the same number of positive and negative words were found on the review, it counts as negative After each review has been classified, the program prints out in the command line the file name of the review, its real class and its predicted clas:s At the end the program should also print how many reviews were correctly classified and how many were misclassified accepted 2. 3. 4. both total number or broken down per positive or negative review are Hint: Java provides the method split() which allows us to split a String into multiple tokens by specifying a separator character. E.g String animals"dog cat bear elephant giraffe"; Stringl animalsArray-animals.split("ls+") For each review Step 0: Open .txt file Step 1: Remove punctuation marks using regex IpfPunct) https://docs.oracle.com/iavase/8/docs/api/iava/util/regex/Pattern.html e.g. review review.replaceAll("llp{Punctj", ""); Step 2: Convert everything to lower case Step 3: Tokenize (split) review using white space as separating character Step 4: Count the number of positive and negative words Step 5: Close .txt file
