Text predictions and text analyzers for Pega Email Bot™ and Pega Intelligent Virtual Assistant™ (IVA) process user input and help the system find the best matching response by using natural language processing (NLP) and predictive and adaptive analytics. You can configure text predictions and text analyzers to detect topics, entities, sentiment, and language in an email, chat text message, or a voice command.
Text analyzer types
Your Pega Platform application supports text predictions and different types of text analyzers that you can add and configure on the Behavior tab in your email bot or IVA channel:
- Exact match
- The default simple text analyzer that exactly matches user input to a response.
- Pega NLP
- An advanced text analyzer that determines the best approximate match by using advanced natural language processing (NLP) and artificial intelligence.
- Text prediction / iNLP
- The default text prediction for the channel is associated with the iNLP text analyzer, as shown in the following figure. The text prediction/iNLP text analyzer detects topics, entities, sentiments, and language in a message by using NLP, predictive and adaptive analytics, and artificial intelligence.
Text analytics model
Text analytics models provide algorithms, NLP, adaptive analysis, and artificial intelligence. To ensure that the text analyzer correctly detects a topic, entity, sentiment, or language, you first train the email bot or the IVA using the data, and then apply the changes to the text analytics model. For more information, see Training the model for the Email channel and Training the model for the IVA channel.
