Sentimental-Analysis

DataRes Project

Download Dependencies

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

• I would recommend creating the virtual environment in a directory (folder) that is specific for the project
• Might need to do python3 -m venv venv instead
• More about virtual environments here

TranscriptCleaner.py

• Tolkenizes and lemmatizes the transcript while filtering out stop words
• Imports the list into a new CSV file python TranscriptCleaner.py
• Make sure you are in the virtual environment that you created (venv)

Importing Data from CSV

This imports the data from a csv file as a list

from csv import reader
with open(____) as file:
    read_file = reader(file)
    list_file = list(read_file)
    data = list_file[0]

• The reason behind data = list_file[0] is that list_file is a list with another list inside (nested list)
  • The list inside list_file (list_file[0]) contains the separated words (tokens)

Frequency Distribution with NLTK

This creates a frequency distrubution of unique words in data

from nltk.probability improt FreqDist
data_freqdist = FreqDist(data)
data_freqdist

Notes

• When opening files, surround the file name with "..."
  • i.e. "file.txt"
