Kolab

Kolab is a student project in the subject TDT4145 - Software development at NTNU. The team has developed a real-time web application which aims at engaging students during classes. With the application you can ask questions during the lecture and give various feedback, such as: "We're moving too quickly", "I fell off", "Speak louder" and so on. Lecturers are able to make a "room" for their lectures, and the students can join the specific room. The lecturer will be able to see the percentage of students who have given the aforementioned feedback as well as the questions. The application utilizes a separate natural language processing script which makes us able to group questions based on their subject.

The project was developed using MEAN stack with socketIO and a separate python script using NLTK and socketIO. Styling was done with CSS and Bootstrap. Publication was done through Heroku and MLab, and testing was done with TravisCI, Coveralls, Mocha and Chai.

Walkthrough for running the project locally

Use npm to install all dependencies

1. Navigate to the folder you've placed the project in with terminal/cmd
2. Install all node package dependencies with: npm install
3. Install all python dependencies with: pip install -r requirements.txt (*the python script and its dependencies require python 3.5+, if you have both python 2.7 and 3.5+ installed you need to specify with: pip3 install -r requirements.txt)

Run the server

1. cd into the directory that contains the server.js file
2. Run the server using this command: nodemon server.js

Run the python script

1. Open the nlp.py file and navigate down to the bottom of the file
2. Change socketIO = SocketIO('kolab-group.herokuapp.com', 80, Namespace) to socketIO = SocketIO('localhost', 3000, Namespace)
3. Use the terminal and cd into the directory of nlp.py
4. Run the python script by running this command: python nlp.py (Same applies here, if you have several python version you need to specify that you're using python 3: python3 nlp.py)
