Guided Labeling for Document ClassificationThis workflow defines a fully automated web based application that will label your data using active learning. The workflow was designed for business analysts to easily go through documents to be labeled in any number of classes. In each iterationthe user labels more documents and the model is trained using the already labeled instances. With every new iteration, the model proposes the most uncertain documents using the entropy scorer node. Once the user is happy with the performanceachieved with the available labels, they can exit the loop and export the model to label the remaining instances. Data Source and LicenseIMDB Review Dataset : kaggle.com/utathya/imdb-review-datasetData License : Database Contents License (DbCL) v1.0 The Process Step by Step1. Upload your documents and enter / upload the labels you want to use2. Start labeling your data3. Monitor model accuracy as you provide more labels4. When the accuracy reaches a desired amount, exit the loop5. Download the model and the labels, and visualize the results Show user currentpredictions and ask formore labels.
