Which statement is a recommended practice when creating an IBM Watson cognitive virtual agent?

Defining different opening sentences is a recommended practice when creating an IBM Watson cognitive virtual agent because it enhances user engagement and creates a more dynamic interaction experience. By varying the opening statements, the virtual agent can avoid sounding repetitive, which can lead to user frustration and disengagement. This practice contributes to a more conversational and natural flow, making users feel as if they are interacting with a more intelligent entity that understands context and can adapt to the conversation.

Introducing variations in the opening sentences also helps in maintaining the users’ interest, encouraging them to interact more openly with the agent. This approach can result in a more personalized experience, ultimately improving user satisfaction and retention.
