I'm currently developing a chatbot tailored for law firms. The primary goal is to enable the chatbot to determine whether the user's case falls within the scope of the legal practices offered by the law firm. If the user's case aligns with the firm's expertise, the chatbot will guide them to the next stage of the conversation. Conversely, if the case doesn't align, the interaction will conclude. Could you provide guidance on how to enable the AI to accurately assess whether a user's case meets the specified criteria and seamlessly direct them accordingly?
