• Statement may contain labels, emojis and negators.

  • Labels are words statement contains e.g. corruption, boycott.
  • Emoji e.g. 😍, 💖.
  • Negators are words that negate something e.g. doesnt, not.

    • This method separate the words from the given statement and returns all words.

  • getDataSet

    • This method has dataset.
    • Labels, emojis and negators already stored in the dataset, which have a positive or negative value.
    • For example "fun": 4, "funeral": -1,
