After preprocessing and artificially translating the data, more dataset files were created.\n\n- Used datasets can be found [here](https://drive.google.com/drive/folders/1-WGObbkfur67vylKkT7mdXsxOMB7czOx?usp=sharing). You can load them directly via the notebook as well.\n\nTrained model is tested against actual product reviews taken from [Skroutz](https://www.skroutz.gr) \n\n##### You can clone the project from repository using the following command:\n\n    git clone https://github.com/JoKoum/Machine-Learning-Project.git\n     \n##### You can create a new virtual environment and install the dependencies using the requirements.txt file:\nOn macOS and Linux:\n\n    python3 -m venv \u003cenv\u003e\n\nOn Windows:\n\n    py - m venv \u003cenv\u003e\n\nPackage installation using requirements.txt file:\n\n    pip install -r requirements.txt\n\n##### more info in [pip and virtual environments](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/)\n\n[Jupyter Notebook Viewer link](https://nbviewer.jupyter.org/github/JoKoum/Machine-Learning-Project/blob/main/Analyze-review-sentiment.ipynb)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjokoum%2Fmachine-learning-project","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjokoum%2Fmachine-learning-project","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjokoum%2Fmachine-learning-project/lists"}
