Movie Sentiment Analysis (Java)

Sentiment Analysis Background

Sentiment analysis is the process of using software to classify a piece of text into a category that reflects the opinion of the writer. Sentiment analysis falls into the growing field of machine learning. In this assignment, you will be writing a simple sentiment analysis program to predict the score a movie reviewer would give based on the words that they use.
 

Sentiment Analysis Algorithm

The goal of your program is to use a data set of known reviews to predict the review for a new piece of text. Our algorithm for sentiment analysis is a simple one: For each word in the input text, calculate the average score of the reviews that use that word per word use. (For the sake of clarity, let’s call that score the “word score”) Then, find the averages of the word scores for the words in your input review. That number is your predicted score for the input text. You should ignore capitalization 
and punctuation.
 

For example, let’s say we have two reviews:

Score: 1, Text: “The plot holes were the most outrageous I’ve ever seen.”
Score: 4, Text: “The outrageous slapstick sequences left me howling.”
In this example, “Outrageous” is used once in a 1 score review and once in a 4 score review. That means that its word score is 2.5. “The” is used twice in a 1 score review and once in a 4 score review, meaning that its word score is 2. If our input text was just “the outrageous,” we would predict a score of 2.25.
