Thanks @aioaneia, I will do the review today.

@HamedBabaei, as you think would be best. This version is from Friday after our meeting. It doesn't contain the new changes discussed. I'm planning a new commit later today.

@aioaneia, thanks for the commits again. I noticed a few minor issues, that it would be great to take into account in the early steps.

1. Please initiate the pre-commit. This would ensure code consistency and avoid pushing the larger files to GitHub.
2. I saw you already made a few larger file commits. Unfortunately, there is a single commit, and it is not possible to revert the larger file commit. One simple solution would be to make a copy of your files in another directory, remove the branch (from github.com), and then try to do the commits again, but this time, before making a commit, add the data/ directory to the GitHub .gitignore file.
3. I recommend changing the src directory name to OntoLearner (or ontolearner) as well. Later we will use this prefix for importing and working with the library.

I hope this will smooth the workings. Feel free to let me know if you need assistance here. I can take care of the changes right away.
