Which is a characteristic of dialog intents?

A characteristic of dialog intents is that they guide the bot's conversation flow. Dialog intents are essential in natural language processing applications, especially in chatbots, as they help determine the direction and context of the conversation based on user inputs. By identifying what the user has said or asked, dialog intents enable the bot to respond appropriately and steer the conversation toward desired outcomes, enhancing user engagement and satisfaction.

The other options do not accurately represent how dialog intents function. For instance, while the system might have predefined intents, not all intents are predetermined; many can be shaped by user interactions and evolving conversation contexts. Additionally, dialog intents do require user interaction to trigger them and are not passive elements that operate without user input. Lastly, they do influence the performance and effectiveness of a chatbot, as proper intent recognition is critical for maintaining a coherent and relevant dialogue.
