Understanding natural language processing
Understand natural language processing features in Pega, explore how to use the processing outcome to create a case, and learn to increase the accuracy of machine-learning models by reviewing the analyzed records and providing feedback.
Exploring NLP features
Learn about natural language processing features in Pega Platform by exploring text categorization, text extraction, and language detection. Use the default examples or provide custom input to classify text into various categories, derive sentiment, extract named entities, and create summaries.
Understanding NLP in the application context
Understand how to use text analysis outcome to create a case and assign it to an operator or a group. After you process input records, you can view a summary report as well as a detailed analysis of individual records.
Updating machine-learning models with feedback
Increase machine-learning models accuracy by updating records that you analyze with your feedback, for example, the correct sentiment value, intent, category, or entity. When you collect the updated records, you can retrain the corresponding model to classify similar records correctly in future analyses.
