Word Classification

In this tutorial we will look at word classification. We will demonstrate step-by-step how to build a classifier to predict food types. Next, we evaluate model accuracy, look at misclassifications, and extend predictions to new foods.
To download the words data file, go to file.biolab.si/.... Or, load this data using the Dataset widget, where you will see that the target variable is already set to category.
We have introduced the Test and Score, Logistic Regression, Confusion Matrix, and Predictions widgets; see classification-related videos from our Intro to Data Science series at: • Cross-Validation
This video is a part of the Text Mining video series that dives into machine learning, visual analytics, and the joys of interactive analysis of text documents using Orange Data Mining software (orangedatamini...).
The word data set used in this video: file.biolab.si/...

easy to understand tutorial

Great video series! I am having a bit of trouble accessing the Corpus widget. I am running Orange 3.36.2. with the Text plugin at version 1.15.0. I tried downgrading the plug-in to version 1.14.0 with no luck. I have tried this on both a Windows and Linux install. I search for Corpus from "search for a widget" menu with no luck. Are there any known issues with the Text plug-in not working properly?

Strange issue. Would you mind heading to github.com/biolab/orange3-text/issues to report the issue? This will help us troubleshoot it.
