Abstract
A chatbot maintains a conversation with a user by providing a plurality of separate conversational tiers that allow the chatbot to interact with the user, each of the conversational tiers having a set of production rules that are independent of production rules for other ones of the tiers. The production rules indicate a flow of conversation between the user and the chatbot. The chatbot selects one of the conversational tiers based on previous conversational tiers used by the chatbot in connection with conversing with the user and based on content of conversations between the user and the chatbot. The chatbot responds to statements of the user according to a specific production rule that is chosen by the chatbot based on a particular one of the conversational tiers that has been selected and based on other factors. A scripting engine may match statements of the user with specific production rules.
