When using ReviewZon, the user can choose their test and train sets. For both, the test set and the train set, the user can decide if they want to use a local (pre downloaded) dataset, or a set of amazon product links from which a dataset of reviews can be built. Using the chosen datasets, a model is trained, validated, and tested. Both the flows are described below in detail.\n\n## Flow\nThere is 3 key aspects to our project:\n - Training the model\n - Visualization of the data\n - Experiments on the model\n\n### Training the model\nOnce the experimentation is complete, the model, hyperparameters and data are all ready.\nNow, we proceed to the step of training the final model. Using the entire dataset as the\ntrain set, and using Logistic regression, we now obtain the final model.\n\nThis model is then applied to a test set, and its results are shown to the user. The model is\nthen saved locally so it can be accessed later. Using the interactive command prompt on\nthe frontend, the user can then test the sentiment of inputs that they feel like testing.\n\n### Visualization\nVisual representation of data is a major part of data science and data mining. \nBy visualizing data, one can easily determine the trends and patterns in the data. \nA lot of visualizations can be done with the data we obtained and processed in the previous steps.\nWe have used the following in our project:\n - Sentiment vs Helpfulness Graph\n - Year vs number of reviews (Grouped by sentiment)\n - Day vs Review Count Graph\n - Rating Distribution\n - Sentiment Polarity Distribution\n - Review Length Distribution\n - Review word count distribution\n - Frequency of words (Grouped by sentiment)\n - Word Clouds\n\n### Experimentation\nWe are using cross validation to choose the best model and hyper parameters.\nWe will validate each classifier and it's hyper parameters using Recall, Precision, Specificity, Accuracy, and most importantly AUC-ROC curves.\n\n### Architecture of the project\n![image](https://github.com/z404/reviewzon-backend/blob/0c3eeef20847aa8e34ad570411c2a85ae730a76e/assets/architecture.png)\n\n## Frontend\n\n### Setup codebase\nNote: To fully experience all the features, you need to setup the backend as well that is found [here](https://github.com/z404/reviewzon-backend).\n\nFirst clone the frontend, using:\\\n`git clone https://github.com/sankalpmukim/reviewzon-frontend.git`\\\nMove into project directory:\\\n`cd reviewzon-frontend`\\\nInstall all dependencies:\\\n`npm install`\n\nIn the project directory, you can run:\n\n### `npm start`\n\nRuns the app in the development mode.\\\nOpen [http://localhost:3000](http://localhost:3000) to view it in the browser.\n\nThe page will reload if you make edits.\\\nYou will also see any lint errors in the console.\n\n### `npm test`\n\nLaunches the test runner in the interactive watch mode.\\\nSee the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.\n\n### `npm run build`\n\nBuilds the app for production to the `build` folder.\\\nIt correctly bundles React in production mode and optimizes the build for the best performance.\n\nThe build is minified and the filenames include the hashes.\\\nYour app is ready to be deployed!\n\nSee the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsankalpmukim%2Freviewzon-frontend","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsankalpmukim%2Freviewzon-frontend","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsankalpmukim%2Freviewzon-frontend/lists"}
